2014 Chevrolet Corvette Stingray




The new 2014 Chevrolet Corvette Stingray will be powered by the previously reported LT1 V8 engine. It is still 6.2-liters, like the outgoing V8 small-block and its estimated to produce 450 horsepower and 450 pound feet of torque. The engine features direct injection and cylinder deactivation to achieve better fuel economy. Power is sent to the rear wheels through either a seven-speed manual transmission or an available six-speed automatic, operated by steering-wheel mounted paddle shifters.






The car was originally rumored to weigh less than 3,000 pounds. Though we do not have the specific weight, but we know it will weigh more than that previous estimate, though probably not much more. As such, it will get from zero to 60 MPH in under four seconds. When equipped with the Z51 performance package, it will achieve over 1-g of lateral cornering force.







Visually, the C7 is a major design overhaul and looks like no Corvette before it. Inside, the cabin is attractive. Previously, to call the Corvette’s interior “spartan” would be a grave understatement. The interior was the major shortcoming of the C6 Corvette. Everything gets soft-touch materials, while the choice of either comfort-oriented GT seats or race-ready Competition sport seats tailors to multiple driving styles.
                                         
 

Press Release:

Chevrolet is redefining modern performance with its debut of the all-new Corvette Stingray. And only a Corvette with the perfect balance of technology, design and performance can wear the iconic Stingray designation.






The 2014 Corvette Stingray is the most powerful standard model ever, with an estimated 450 horsepower (335 kW) and 450 lb.-ft. of torque (610 Nm). It is also the most capable standard model ever, able to accelerate from 0-60 in less than four seconds and achieve more than 1g in cornering grip. It is expected to be the most fuel-efficient Corvette, exceeding the EPA-estimated 26 mpg of the current model.

“Like the ’63 Sting Ray, the best Corvettes embodied performance leadership, delivering cutting-edge technologies, breathtaking design and awe-inspiring driving experiences,” said General Motors North America President Mark Reuss. “The all-new Corvette goes farther than ever, thanks to today’s advancements in design, technology and engineering.”
The all-new Corvette Stingray shares only two parts with the previous generation Corvette. It incorporates an all-new frame structure and chassis, a new powertrain and supporting technologies, as well as completely new exterior and interior designs.





“Stingray is one of the hallowed names in automotive history,” said Ed Welburn, GM vice president of global design. “We knew we couldn’t use the Stingray name unless the new car truly lived up to the legacy. The result is a new Corvette Stingray that breaks from tradition, while remaining instantly recognizable as a Corvette the world over.”




The new Corvette Stingray will be built at GM’s Bowling Green, Ky., assembly plant, which underwent a $131-million upgrade, including approximately $52 million for a new body shop to manufacture the aluminum frame in-house for the first time.


“We believe the Corvette represents the future of modern performance cars because it delivers more power, more driving excitement and better fuel efficiency,” said Tadge Juechter, Corvette chief engineer. “The result is better performance by every measure. The 2014 Corvette delivers the fastest acceleration, the most cornering grip, the most track capability, the best braking performance and what we expect to be the best fuel economy ever for a standard Corvette.”

The 2014 Corvette Stingray coupe goes on sale in the third quarter of 2013.

Ferrari F12 Berlinetta






What is it?

The Ferrari F12 Berlinetta is the fastest, most powerful product ever offered by the world’s most fabled supercar constructor for use on the public road. The 119bhp increase in engine power over the 599GTB is the largest hike in output of any Ferrari over its immediate predecessor and, with that, comes a 60kg reduction in weight.






But for all its new found urge, the F12 is a traditionalist Ferrari at heart. It places its normally aspirated V12 engine in the nose, its gearbox between the rear wheels, leaving space for just two occupants inside. And you could have said as much about the 275GTB, almost half a century ago.

And just like that old Berlinetta, with this new one it is the engine that dominates the headlines. You can pore over its active brake cooling ducts and its downforce-enhancing aerodynamics all you like, but they won’t divert your attention from that motor for long. From less than 6.3-litres it generates no fewer than 730bhp at 8250rpm. That’s 70bhp more than a 599GTO and 39bhp more than its closest rival, the Lamborghini Aventador. Even comparison to the million pound Bugatti Veyron is not as irrelevant as you might expect: sure the Ferrari can’t compete with its 987bhp output but factor in weight and you’ll see the Ferrari’s 448bhp per tonne is not that far from the two tonne Bugatti’s at all.

The F12 costs £239,736, an increase of £27,640 over the 599GTB or, put another way, a smidge less than a BMW 320d SE. Then again that’s also the amount of money the typical customer is likely to spend just on options, which means that for almost all owners, the F12 is a quarter million pound motor car.


What is it like?


Engine aside, the F12’s greatest strength is its least obvious. It’s not just lighter than a 599, it’s smaller too: however you measure it – length, width, wheelbase or height, there’s just less of it, making it feel a substantially more compact car. This is just as well because when that V12 lets rip, you won’t need the car’s size adding to the intimidation.

For this is a car that will beat a McLaren F1 to both 60mph and 125mph. And it will do it in one, seamless, its double-clutch gearbox ensuring literally no pause between shifts. And when you hear how it works above 8000rpm, you’ll wonder not how the 8700rpm limit got to be so high, but why it seems so low: this engine feels like it could go on forever.




How do you harness that? How do you transmit 730bhp to the public road through the the rear wheels of a front engined sports car? Ferrari has done astonishing work here. Thanks in varying degrees to an even more rear-biased weight distribution (46/54 per cent front to rear), new suspension, Ferrari’s E-diff and specially developed Michelin, Pirelli or Bridgestone tyres, the F12 puts its power down better than you could imagine. Of course you can leave the electronics to identify the adhesion limit but the F12 is so clean in its power transmission, at times the black lines in the mirror are the clearest indication that you’ve broken traction.

In corners it is, of course, a very different matter. It should be said that the F12 is not a particularly easy car to drive very fast on road or track, and not just because the scenery is so accelerated by that engine. Then again if you leave the manettino control in ‘Sport’ or even ‘Race’ it looks after you so well, it’s perhaps too easy to forget the exact nature of the beast with which you’re dealing. Turn off the electronics, let the car be itself and you’ll soon find out.





This is a car that understeers a little and then oversteers a lot and, at first acquaintance, it’s quite disconcerting. Your disquiet comes not from the power but the steering. Ferrari has not only shortened the car’s wheelbase, it has also substantially increased the speed of the rack which, in my view, is a mistake.

The big reaction you get to any given input might give the car some superficial sportiness, but it also makes the car more difficult to drive, requiring more precision from the driver in general and in particular when the back gets loose. You don’t want a rack so slow you can’t get the lock off in time but within reason, the slower the steering the wider the ‘catch’ window is opened. The good news is that, steering aside, the chassis is faithful and the engine which you might think could be the architect of your downfall, is more likely to be your saviour: so precise is its throttle response, you’re extremely unlikely ever to mistakenly call for more power than intended.







We should not forget this is a dual purpose car. Unlike the purely sporting 458 or the dedicated GT that is the FF, the F12 has to place a wheel in both camps and while it rightly errs more to the sporting side, it has not forgotten its other role in life. Ride quality on rough roads is adequate thanks to a specific ‘bumpy road’ setting for its suspension available regardless of manettino position, while refinement is extremely good. You might think a 730bhp V12 might never know when to shut up, but at a steady 80mph on the autostrada, this is a commendably civilised conveyance.





It’s spacious too with head and legroom aplenty despite its shrunken dimensions. Oddment stowage space on board is poor, but the boot is an excellent size and if you remove the shelf between it and the cockpit, utilising the space behind the seats, implausibly it’ll hold the same amount of clobber as a BMW 7-series. The interior design is less impressive, with too much plastic and a style too derivative of lesser Ferraris for this kind of money.



Should I buy one?




Have you got £239,736 to spare? If so and if you like the idea of traditional V12 Ferrari sports car turned up to about 27 then, yes, wake your dealer in the middle of the night and bag your space before that list gets any longer. Just remember this car is not a paragon of virtue, its steering alone sees to that. And while it is undoubtedly Ferrari's fastest to date, it’s still not its most exciting. Ferrari will be sick of hearing it, but Ferrari’s most thrilling driving weapon remains the F40.

But as a device that can be used everyday (as 20 per cent of owners will), for taking long journeys laden with luggage and then, when you arrive, leaving the other half in the hotel and heading for the hills, I’m not sure it has an equal. A Veyron is not just four times more expensive, it’s less practical and not as fun to drive. An Aventador offers a greater sense of occasion while subjectively its engine is actually at least a match for the Ferrari’s, but it’s let down by its handling, its gearbox and relative lack of carrying capacity.

Once you’ve vacated the car and let your pulse return to something approaching normal, it becomes clear that this car’s greatest strength and biggest surprise is not how unfathomably fast it is, but how usable the car remains. For all its McLaren-melting acceleration, the F12 is not a recreational plaything, but a deadly serious working tool. That is the key to this car’s extraordinary character and why it ranks as one of Ferrari’s finest achievements to date.

Mercedes-Benz Brabus SLS AMG 700 Biturbo









The Geneva Motor Show is now upon us, and just as the sun is bright and the wintertime is as cold as the other side of the clouds, German tuning firm, Brabus, has finally unveiled their tuned-up SLS AMG masterpiece.


Calling it the BiTurbo 700, which was taken after the performance upgrades done on the car,Brabus seems to have done its homework quite well with their work on the Mercedes supercar. Not only does the car generate more power than the stock SLS AMG, it also has plenty of aerodynamic upgrades that make the car look sportier and far more aggressive. Brabus also did well for themselves in giving the SLS a matte gray exterior finish, adding style and class to an already sporty and powerful machine.


We’ve seen a lot of works done by Brabus over the years, but we can honestly say that this particular program ranks right up there with the Rockets.


Exterior





Brabus had one thing on their mind with the SLS AMG: make it look sportier and more aggressive than it already is. So the German tuning firm outfitted it with their WIDESTAR wide-body kit made from strong and lightweight carbon fiber compounds, which inevitably add 20 millimeters on the SLS AMG’s overall width. From there, Brabus was able to put in a set of their own Monoblock F "PLATINUM EDITION" ultra-light forged wheels.


The front of the car was retrofitted with numerous items, all in the name of aerodynamic stability and the ability to be faster than standard SLS AMG units. Among the items added include a Brabus front spoiler that reduces the lift on the car’s front axle at high speeds. There are also two Brabus covers for the upper air inlets in the car’s apron, giving the SLS AMG an even more menacing scowl upfront. Over at the back, Brabus put in a spoiler on the trunk lid and a diffuser, while also installing side air outlets on the rear apron. As for the sides, Brabus added side skirts and gills for the front fenders. These gills have a unique characteristic in that they illuminate the Brabus lettering in a blue hue.

 Interior





As one of the best Mercedes tuners on the planet, Brabus is known for putting together quite an interior package with this particular project being no different. For this model, Brabus outfitted the car with a black and white leather upholstery with contrasting stitching and paired it with matte anodized aluminum pedals and foot rests. On top of that, the car also gets a new ergonomically-shaped sports steering wheel, a speedometer that has a dial that goes all the way up to 250 mph, and a choice of matte or shiny carbon fiber elements, which can be customized according to the preferred color of the customer.
Performance






The Mercedes SLS AMG already has a 6.3-liter V8 engine with 571 horsepower and 650 Nm of torque, mated to a seven-speed dual-clutch transmission so on its own, its already got enough power to match wits with any car that crosses its path. But as it turns out, the boys from Brabus aren’t as convinced. So they did what any self-respecting tuning shop would do when faced with such a quandry: add more power.




Thanks to a B63 bi-turbo system, Brabus was able to squeeze out more horsepower on the SLS AMG to the tune of 700 horsepower and 626 lb/ft of torque. As a result, Brabus’ SLS AMG can now hit 0-60 mph in just 3.7 seconds with a top speed of 213 mph.
Pricing





Brabus has no pricing figures for the 700 BiTurbo SLS AMG, but just like we did with the Hamann Hawk, we’re estimating the whole enchilada to cost somewhere to the stratosphere of $200,000. We’re even going out on a limb and saying that Brabus’ work could be a tad more expensive than Hamann’s ’Hawk’ SLS AMG.
