2014 Nissan GT-R first drive review

Subtle changes make standard GT-R more appealing to drive, but by creating the GT-R Nismo, Nissan has left us with the job of choosing between the two...

What is it?

MY 14 to replace MY 13. Or that's what Nissan dubs its conveyor belt of model year changes; to everyone else it'll simply be the GT-R they receive if they order after December.

In previous years the difference between model years was fairly inconsequential, but this time round there are some genuine differences - in the most part because 2014 marks the point at which Nissan has opted to split the range in two.

Reviewed elsewhere, the more expensive Nismo will now be the performance pinnacle of the GT-R experience. Its placement means that the engineers have finally been freed to relax their grip on the Race part of the badge, and get to grips with the GT bit.

Thus, ride and refinement have become bigger issues than they have ever been before. The front spring rates and electronic control of the dampers has been revised “to reduce load fluctuations between the four wheels” ie to keep them all in contact with the ground rather than skipping around like frogs in a pond of trampolines.

Dunlop SP Sport Maxx GTs now come as standard, and the steering has been retuned to offer drivers a bit more assistance at lower speeds (where the GT-R was previously as cantankerous as Godzilla in a tea shop). The brakes have also been recalibrated for a more linear response when not on the limit.

Nissan has even set out to improve the car's insulation from the whine of the drivetrain, reassessing the placement of noise-cancelling material and indulging in Active Noise Control from the Bose sound system.

Finally (or possibly firstly, depending on how you look at it) there has been the usual deck-shuffling of light clusters, with the front getting rather dashing LED lamp signatures to the front and a more distinctive 'four ring' arrangement at the back.

What is it like?

Really rather convincing. Previous trips out in the GT-R would not last five minutes before the suspension was frantically thumbed into its 'Comf' mode. Here, on admittedly smooth Japanese roads, the softest setting was not required to reasonably satisfy one's aching spine.

Its engineers bridle at the suggestion of softness; what they've strived for, they say, is improved compliance for better traction, and there is that sensation - not plush or tremendously isolating, but sufficient to make the GT-R a better everyday prospect (obviously the point).

Similarly, the new steering does make junction navigation a little less bothersome, and work at the opposite end to make its responses more linear (and less in need of minor corrections) has also paid off.

A modest route hardly permitted a decent work out of the GT-R's formidable dynamic, but it's fair to say that when prodded, the car still responds with huge conviction. Revised throttle response, beyond a moment's pause for thought, is aggressive and then relentless. Nissan doesn't quote a 0-60mph time for the new Nismo, but the standard car is still below 3, and that'll be plenty good enough for most.

Suzuki SX4 S-Cross review

Second-generation soft-roader enters the family crossover fray

The Suzuki's low price tag will make it appealing to many

Where the crossover begins and the SUV ends are muddy waters, but there's absolutely no doubt that the Suzuki SX4 S-Cross – and the SX4 line – owes its existence to the range of small off-road vehicles that Suzuki has been building since 1968.

The latter-day variant, mostly forgotten, is known as the Jimny and has been with us since 1998. That's a rather staggering display of longevity in itself, but only an equal to the previous SJ-series, and still a junior compared with the original LJ ('light jeep') design, which soldiered on from 1969 to 1981.

But Suzuki’s offering was too small, too feebly marketed and probably still too quirky for it to reach the tipping point that would be Nissan’s decade-defining automotive achievement.The previous SX4, a five-door, Giugiaro-penned hatchback, predated the original Qashqai, already traded under the correct name and sported that oh-so familiar 4x4 look now seemingly craved by an ever-growing number of buyers.

Second time around, Suzuki now insists it has got the new model right. Dubbed the SX4 S-Cross, this second-generation incarnation shares nothing with its predecessor. It is now a proper C-segment contender, with one of the biggest boots in the class and offered with a choice of two highly economical four-cylinder engines

Better still, Suzuki boasts that it has been engineered by the same team responsible for the Swift – our preferred cut-price supermini. So in the S-Cross’s case, is bigger better?

Peugeot 308 1.6 HDi first drive review

Classy, high-quality cabin and good motorway manners heralds Peugeot’s return to form in the hatchback segment

What is it?

The new Peugeot 308, fresh on the scene in the UK. It’s a car with a very fulsome engine range, largely because PSA is right in the middle of the switchover from ‘Euro-V’ to ‘Euro-VI’ emissions-compliant motors, but clarity will come in time. 

We’ve had test experience of the mid-range 114bhp e-HDi turbodiesel, and will wait until thespring 2014 to try the full-house 148bhp 2.0-litre BlueHDi and the remarkable forthcoming 118bhp, 1.6-litre, 82g/km oil-burner – the latter a car with the potential to show a VW Golf BlueMotiona thing or two on fuel-sipping.

For now, we’re sampling the 91bhp 1.6-litre turbodiesel – the car that, in ‘Access’ trim, provides a sub-100g/km, £16.5k oil-burning entry point to the 308 range. Our test car is in slightly richer ‘Active’ spec, but still looks good value at under £18k.

What is it like?

Classy, upmarket and very pleasant indeed to spend time in. If habitual critics of French cars spent two minutes in this cabin, the greatly improved material quality will certainly make a good proportion of them think again. 

The 308’s is a sculptural, substantial and swish interior with a central colour touchscreen interface that has permitted a major decluttering of the centre stack. Even lower-middle spec versions get expensive-looking trims and generous equipment levels (sat-nav as standard on a sub-£18k car, anyone?). Rear cabin space isn’t quite as generous and the seats could be more comfortable, but you get a big boot for your money, too.

Mechanical refinement is the 308’s next most convincing attribute - even this 91bhp turbodiesel is hushed and smooth compared to most like-for-like powerplants – and after that, the car’s quiet and pliant motorway ride distinguishes it best. 

It’s a compliance, like so many, that is best delivered at the cheaper end of the model spectrum. Peugeot’s modus operandi on chassis tuning automatically gives cars with heavier and more powerful engines, bigger wheels and more fitted equipment slightly firmer suspension, and so full-house versions of the 308 not only produce more road noise, but ride less calmly, too.

But our Active-spec test car had an absorbent primary ride over low-frequency bumps, and while it lacked the fluency, wheel travel and subtle damper response of Peugeots of old when dealing with smaller and sharper intrusions, it still merits a rank among the most comfortable hatchbacks in the current class.

Performance suffers with poor turbo response at times, but feels entirely adequate otherwise, and the car’s handling is more than decent too, but the latter is the dynamic facet most likely to divide opinion. Through a downsized steering wheel, the car feels direct and wieldy at low speeds just as a 208 does, but has inconsistent levels of steering assistance and only sporadic feedback. It’s also easy to overwork the front contact patches in greasy conditions at fairly high speeds, and to bring about understeer sooner than you might have otherwise.

McLaren F1 1992-1998 review

In 1994 Autocar road tested the fastest and most extreme road car ever built. Here is the definitive verdict of the McLaren F1

The F1 is untouchable in a straight line: 0-100mph in 6.3sec

"What you are about to read is not simply the fastest road test in history. It is, in all likelihood, the fastest road test there will ever be.

"Until we strapped our equipment to the McLaren F1 no one knew how fast it would go. Now we know it all, because we have driven it beyond 210mph, timed it to the last hundredth of a second. And here it stops.

Those were the words that introduced Autocar's review of the McLaren F1 in 1994. To this day, it remains the definitive road test of the most iconic British supercar of all time. "McLaren will never release another of its amazing £540,000 supercars for road testing to anyone, anywhere in the world."

It was such a hammer blow that it took McLaren 21 years to produce a supercar capable of coming close to the F1.

In May 1994 we took the fifth McLaren prototype, codenamed XP5, to two proving grounds – Millbrook and Bruntingthorpe – to attempt to generate a full set of performance figures. That same car was driven, four years later, by Andy Wallace at Ehra-Lessien in Germany to record a world record-breaking 243mph.

Here, as McLaren launches the P1, we republish that original Autocar road test from May 1994.

Mazda 3 hybrid first drive review

Although it's not destined for the UK market any time soon, this Mazda hybrid offers a more stylish alternative to established players like the Toyota Prius

What is it?

Mazda’s first-ever hybrid, a version of the all-new 3 saloon just launched at the Tokyo motor show.

Built around a 2.0-litre petrol engine, the main electrical componentry has been bought in from Toyota and integrated with Mazda’s four-cylinder petrol.

These aren’t Toyota’s latest hybrid parts, however, they were developed for the first-generation Prius in the late 1990s.

Nevertheless, this is a sophisticated hybrid with a complex epicyclic transfer box and CVT to juggle power between the petrol engine, electric motor and front-wheels.

It also benefits from the latest knowledge in tuning and setting-up hybrid systems, so Mazda says it has extracted the maximum from the hardware.

The battery pack is nickel metal hydride, fairly compact and packaged next to the rear bulkhead, where it makes a limited impact on luggage space – which numbers 312 litres, a reduction of 107 litres.

What is it like?

Progress is smooth and efficient, Mazda clearly having successfully integrated the petrol engine and electric motor.

This makes the Mazda 3 a competitive hybrid against the latest rivals, which is particularly noticeable compared to the original Prius, a relatively crude device at its introduction.

It also shows how detailed engineering and greater knowledge can squeeze improved performance from older tech electrical componentry.

However, we’d still like more refinement from the CVT gearbox and engine. They operate smoothly enough, but as the CVT feeds in the power, the engine noise is too obtrusive as the revs constantly rise and fall.

Tyre noise was surprisingly vocal too. That could have been a coarse road surface, but our experience of Japanese tarmac is that it is smoother than UK roads by a fair margin.

Also, like most hybrids the fuel economy indicated in-car fell below the quoted figure. However, this was a short urban drive and the figure of 52mpg is comparative with what a Toyota Prius might typically deliver in give-and-take driving.

Other aspects of the new Mazda 3 are impressive, too. The cabin quality is high, the instrument pack is attractive and the driving position gives good visibility.

There wasn’t a chance to evaluate handling to a significant degree, but the 3 hybrid turned in faithfully, roll was resisted reasonably well and the chassis felt like it will deliver a fair balance between ride and handling.

Should I buy one?

Britons are unlikely to ever get the chance, hybrids not featuring in Mazda’s European plans. But we can see the Mazda 3 garnering a strong following in the home market, where hybrids dominate the small hatch market segment. As a stylish alternative to the ubiquitous Toyota Prius, the Mazda 3 hybrid looks to have a strong future.

Ferrari F12 Berlinetta review

Can Maranello evoke past greats with its latest front-engined V12?

The F12's styling owes more than a little to the 275 GTB

When Maranello announced the Ferrari F12 Berlinetta on the eve of 2012's Geneva show, its billing as the fastest road-going Ferrari ever made, either in terms of bald acceleration or around the firm’s Fiorano handling circuit, or indeed anywhere, was formidable.

The supercar cognoscenti would probably still be in awe of all that now, if it weren’t for the models that Ferrari has unveiled since: specifically, one headline-stealing 950bhp hybrid.

Although Ferrari has been making front-engined V12 grand touring sports cars for the road for almost six decades, the car to which the new F12 owes its biggest debt is probably the 275 GTB of 1964 Overshadowed or not, though, the Ferrari F12 Berliner is a landmark in its own right, and having been to Italy to sample it, witnessed it disdainfully dismiss the equivalent Lamborghini in a comparison test and seen it come painfully close to scooping our 2013 Best Driver’s Car title, it’s time to get well and truly under this car’s ingeniously sculpted aluminium skin.

Since the 275, Maranello has made equivalent front-engined V12 models in the form of the 365 GTB/4 (Daytona), 550 Maranello, 575M and 599. But during a 23-year gap between the Daytona and 550, it abandoned the front-engined V12 concept to experiment with mid-engined flat 12 models like the Testarossa.

It’s not just those with a cool quarter of a million pounds of vested interest in this car who will be interested to discover the full breadth and scope of the Ferrari F12’s talent and stature however, and nowhere will you get a fuller picture.

Toyota i-Road first drive review

What is it?

In the words of its creator Akihiro Yanaka, the Toyota i-Road combines “the manoeuvrability of a motorbike, with the economy and stability of a small family car.”

A tandem two seat three-wheeler, it tilts into bends while being steered from the rear by a tiny single wheel. Propulsion comes from a pair of electric motors located within the front wheels. In the UK it would be classified as a scooter, allowing it has a slightly disappointing 28mph top speed – for Japan this climbs to a more exciting 37mph - and has a range of just over 30 miles when driven with a bit of restraint, and 25 miles if you can’t resist extracting the most of its darting charms. It takes three hours to recharge.

The i-Road is intended purely as a set of urban wheels and promisingly,Toyota plans to trial it in both Toyota City, near Nagoya, and Grenoble in southern France as part of a 70-strong fleet of tiny electric tandem two-seaters entering service in autumn next year.

The other vehicle, known as the COM, is a four-wheeler similar in concept to Renault’s Twizy, if less sexy looking. The i-Road, by contrast, looks very sexy indeed. Styled by Koji Fujita, this is the concept as it appeared at last year’s Geneva motor show, from its ‘50s locomotive style Cyclops headlight to the slender casings that cap its tilting front wheels and the horizontal strip of its tail-lights. It’s less than 2.5m long and rides on a 1700mm wheelbase, but the critical statistic is its 850mm width.

That’s about the same as a motorbike, making the i-Road very easy to thread through city streets, while allowing no less than four of them to occupy the parking space of a single car. 

Its mechanicals are no less interesting than its looks. The slender front wheels are jointed to a yoke system that allows them to tilt – imagine a see-saw with a pair of vertical struts descending to the wheel hubs from either end – while the rear wheel steers at a variable rate depending on your speed, turning more tightly for a given lock at lower speeds. Manoeuvrability is the key.

With two motors up front the i-Road needs quite a complex control system in order that they don’t fight each other in a straight line, besides enabling one to spin more slowly than the other in a turn. With only two kilowatts apiece to dispense – that’s a little over 5bhp – minimising the i-Road’s weight has been critical, the three-wheeler weighing around 300kg in concept form. However, this example uses an aluminium chassis that would be too expensive for a production version, which would probably resort to steel.

Nissan Note review

The new Nissan Note occupies a segment that's tough to love: that of the supermini-size MPV.

As packed with cost-effective worthiness as they may be, most inflated superminis inspire a level of must-have desire roughly equivalent to that of a built-up shoe.

By seeking to do an unglamorous job in the most inoffensive way possible, most disappear under the car-fancier radar and get hoovered up by mature buyers who sensibly value decent ingress and egress more than a raked B-pillar.

This self-limiting fact has clearly not passed Nissan by. The previous Note was typical of the breed, and although it found a grateful audience (not to mention a four-star road test grade), it was too tall and boxy to effectively battle the cutely turned – and massive-selling – Ford Fiesta and Renault Clio.

The new model, underpinned by an entirely new platform and cleverer engines, seeks to redress that balance. As before, the Note is built in Britain at Nissan's Sunderland factory. Its 'V' (for 'versatile') platform is shared not with the new Renault Clio, despite the Nissan/Renault alliance, but with the current Micra, albeit suitably enlarged in this instance.

It still claims highly competitive practicality but has adopted a much more typical supermini body that, Nissan hopes, will prove more palatable to a much wider pool of potential customers.

Mercedes-Benz E-Class review

The E-class is a refined and relaxing return to old Mercedes qualities

Has there ever been a car offered for sale with a broader remit than the Mercedes-Benz E-class?

We’re not just saying this because the car is offered for sale as a saloon, estate, coupe and cabriolet, for there are many others you can buy in just as wide a number of configurations.

But we know of no other car that can claim on the one hand to be a supercar with more power than astandard SLS, on another the most capacious estate money can currently buy and, on a third, far and away Germany’s most popular taxi. If versatility alone decided such things, the E-class would be the class leader at a canter.

Its competition, however, is stronger than ever: the BMW 5-series is an ever-present threat while the Jaguar XF is always going to attract the eye of aesthetes and enthusiasts alike. Even the Audi A6, the one car in the class you could once always have counted upon to fail to beat the best is now a formidably able contender.

Now comfortably past its mid-life facelift, the current generation of E-class comes with a rationalised range, though to see how much choice remains available it may be hard to believe it.

However ninety per cent of E-classes sold in Britain are powered by diesel and here the choice is between two standard 2.2-litre four cylinder engines producing 168 and 201bhp respectively, a diesel hybrid based on the same unit with 228bhp or a V6 3-litre diesel offering 249bhp and only a fraction less torque than that aforementioned SLS.

For those not yet persuaded by the black pump you can either have a 2-litre petrol engine with either 181bhp or 208bhp or a 5.5-litre twin turbo V8 in the AMG developing 549bhp in standard trim and that SLS-busting 577bhp for the ‘S’ model. Between these poles there is no middle ground.

Range Rover LWB first drive review

At £105,840 though, it's a very expensive optionYes, there really are people out there for whom the Range Rover’s sky-high levels of refinement, the silky smooth powertrain, the commanding driving position and sheer breadth of dynamic ability are not the main attractions. They like to sit back, relax and enjoy the ride in the sumptuous interior from one of the seats without a steering wheel in front of it.

And those types of Range Rover customers now have their very own model. The long-wheelbase Range Rover grows 200mm in length over the standard model on which it is based to 5199mm, the bulk of this increase going to rear passengers, who can enjoy an extra 186mm of legroom.

That growth comes by extending the bodyshell in front of the rear wheels, but some subtle styling tricks mean that at first glance you don’t see the extra bulk the extra length brings. The Range Rover’s classic proportions remain intact, in other words.

The car will be coming to the UK in March next year offered with the 4.4-litre SDV8 diesel engine (£102,120) and the potent 5.0-litre V8 Supercharged (£105,840) range-topper we’re testing here. Autobiography trim is the sole offering from launch. 

What is it like?

Before we play chauffeur, it’s only right to be chauffeured first, given that’s where most of the long-wheelbase Range Rovers owners will be spending their journeys. They won’t be disappointed. 

A standard bench or optional individual chairs feature, either of which can be reclined up to 17 degrees, up from the eight degrees of the standard wheelbase model. There’s all sorts of toys and tricks that can be specced, to, from large TV screens to a front passenger seat that slides all the way forward into the footwell to create a long space you could host an Ashes test match on. 

On the move, the ride quality is fantastic, isolating you from broken and rutted town surfaces, and remaining composed and stable on high-speed roads. It’s smooth and comfortable enough in the back to do work, have a snooze, make some important decisions, or whatever folk who like to be driven around do.

Should the owner want to give their chauffeur the night off and drive to, erm, Waitrose, Carluccio’s or the BAFTAs themselves, they’ll enjoy life from the driver’s seat just as much.

The biggest compliment to pay to the car in the way it drives is to say it feels like a Range Rover Supercharged with a standard wheelbase, despite its extra size and weight over an already big, heavy car. The straight-line performance is prodigious, visibility is of course excellent, the handling sure-footed and confidence-inspiring, the car being easily placed in a corner.

Should I buy one?

This is a car that pushes Range Rover fully into Bentley levels of opulence, and a worthy rival to a Mercedes S-class in terms of a car you’d like to be driven in as well as drive.

Porsche 918 Spyder first drive review

Our first drive in the new Porsche supercar reveals a model with amazing potential. McLaren and Ferrari should be nervous

The 918 feels natural on the road, and that's how it should be

What is it?

The 918 Spyder is, according to Porsche, the future of the sports car. It's also the spiritual successor to a whole host of Porsche's most classic hypercars from the past - from the 959 to the Carrera GT - and is a technological tour de force at the same time. 

In combining 4.6-litres worth of high revving, race-bred conventional V8 engine with electric motors that power both the front and rear axles, it is, for the time being, the fastest road car on the planet, with a combined power output of 875bhp at 8500rpm and a thumping 944lb ft of torque. 

And before you reply with a cynical "Yes, but its lithiom ion battery pack means it weighs far more than it should, so it's not as quick as it could be were it a pure sports car" consider this: the battery pack on its own does indeed add some 314kg to the car's kerb weight, but without its hybrid powertrain Porsche says the 918 would be more than five seconds slower around the Nürburgring.

In other words, the Spyder's combination of batteries, electric motors and conventional combustion engine power do not mean it is in anyway compromised as a design but, instead, optimised to deliver as much performance but also as much economy at the same time.

And the numbers it produces are truly extraordinary. As in sub seven minutes around the Nürburgring, 0-60mph in 2.5sec (in Weissach specification), 0-186mph in 19.9sec (again in Weissach spec) and between 25-30mpg when tootling about in the real world. Genuinely.

Forget for a moment the headline-grabbing 94.1mpg claims, they are generated with the car driving only in Hybrid mode; the reality is that the 918 will burn about the same amount of fuel as a high-ish powered saloon car during regular on-road driving.

Which is nothing short of incredible, you'll agree, but is also the 918's reason to be - because job one when the project started was to build a super-sports car that could return 3.0-litres per 100km (94.1mpg), which could also lap the Nürburgring in 7min 15sec. Which also means the car has massively over delivered on the performance front in its final showroom specification.

And the cost for all this magic? 781,155 euros (£652,849) in standard specification, or 853,155 euros (£712,088) in 41kg lighter Weissach Pack spec.

Lamborghini Aventador roadster review

The Lamborghini Aventador LP 700-4v roadster is the most extraordinary car in the company’s illustrious 50-year history, or so said the firm's charismatic chairman, Stephan Winkelmann, at the car’s launch in Miami.

Don’t for one moment think of the roadster as some kind of folly, however, or as a car that hasn’t somehow been engineered thoroughly for the job. Unlike the Murciélago roadster, which was something of an afterthought to be honest, the open-top Aventador is a standalone model in its own right.Then again, one look at the mightyAventador roadster in the flesh tells you that it is indeed right up there with Lamborghini’s most outrageous creations. It looks like the sort of car Batman might drive on his day off, maybe when he’s on holiday in Miami Beach.

Its styling is unique, considerable care and attention having been employed to ensure it of a separate, more extrovert personality compared with the coupé. And beneath its reptilian-like skin, while it shares its basic carbonfibre tub platform, 6.5-litre V12 engine and seven-speed single-clutch gearbox with the coupé, dynamically it is perhaps more impressive than the fixed head, for reasons we’ll come to in a moment.

Despite weighing some 50kg more than the coupé, Lamborghini claims the Roadster can set exactly the same time around the number one handling circuit at the Nardo test facility in the hands of all its test drivers.

Had the roof simply been removed and various areas of the car not been redesigned to accommodate the one quarter decrease in stiffness, there is no way the Roadster could achieve such basic speed across the ground.

On the road that’s exactly how it feels: pure, fast and sharp, and perhaps even a touch more precise than the coupé at the front end thanks to the fitment of bigger diameter tyres (optional 21-inch 355/25s at the back with 20-inch 255/35s at the front on the one we tested). These, say Lambo’s testers, make a small but key difference to front-end bite during the turn-in phase.

The result is a car that's less prone to understeer in slow corners (which is welcome) without there being any extra nervousness at the back in fast corners (ditto). Overall the Roadster just feels like it has more grip than the coupé everywhere, basically, and at least as well balanced near its monumental limits.

So although it might weigh an extra 50kg, the roadster gives little if anything away to the coupé from behind the wheel. Other than the fact there’s no roof, it even feels the same when you’re in the driving seat, which is no surprise given that the dashboard, instruments, switchgear and seats are all identical to those of the fixed head.

The roof itself comes in two forged carbonfibre panels that are removed by unlocking a couple of latches and lifting them out manually. Each panel weighs just 3kg and stores neatly beneath the bonnet in the boot. Once in situ they render the luggage capacity all but useless, but then, asLamborghini says, “You don’t buy a car like this to go shopping with”. Which is fair enough, even if it would be handy to be able to put something slightly larger than a toothbrush in the boot when the sun comes out.

Rather more impressive (and entirely believable) is Lamborghini’s claim that the roadster can reach its astonishing 217mph top speed with or without the roof in place. The highest speed I reached was about 160mph along the main straight at the Homestead-Miami Speedway, at which point any noise being generated by the wind was drowned out completely by the machinations of that monster V12.

At lower speeds, however, it’s clear that Lamborghini's designers and aerodynamicists have done a fine job of managing the flow of air away from the cockpit: at 80mph with the windows up and the small rear bulkhead screen raised, conversation is remarkably easy to maintain.
