Corvette gets slidey with Britain's best performance cars

Autocar wants to find Britain's best driver's car, and it's challenging a murderers' row of some of the world's best performance vehicles to find out, including the latest Chevrolet Corvette Stingray. All of them were therefore assembled at the Castle Combe Circuit to find a winner.
If it wants to take the crown from this pack of mostly European competitors, the 'Vette has to beat some steep competition. Its challengers include monsters like the Ferrari 458 Speciale, Ariel Atom 3.5R and Jaguar F-Type Coupe. As a further hurdle for the winner to clear, Autocar also has last year's champ among the fighters - the Porsche 911 GT3.
Even if you're not at all interested in the C7, there's still something here for practically any fan of fast cars. The competitors include relative oddities among the pack like the Renault Mégane RS Trophy and Alfa Romeo 4C. Plus, Autocar has some well-positioned microphones that let you hear the Atom wailing like a banshee and the roar of the 458 Speciale. Check out the video to see which one of these all-stars takes home the award this year.

BMW details cheaper, sub-M performance cars for young 'brand ambassadors'

BMW's M cars are undoubtedly some of the best sport sedans in the world. Unfortunately, their prices put them out of the reach of a huge segment of buyers, many of them young. However, that might change in the near future as BMW launches its M Performance Automobiles performance sub-brand, positioned between its standard cars and the full M models.
Traditionally, M car buyers have been male and in their early-40s, according to Oliver Ganser, product strategy manager for BMW North America, speaking to Automotive News. However with MPA, BMW hopes to find even younger buyers "who will be brand ambassadors and appeal to the real enthusiasts that we have," he said. These new MPA models will see a mild boost in power and handling from off-the-shelf parts, instead of the unique engines and cutting-edge tech from their bigger M brothers.
The M Performance Automobiles line was launched last March at the Geneva Motor Show with high-performance diesel models of the 5 Series, X5 and X6. The first of the MPA models coming Stateside, the M235i, launches in March. We liked it when we drove it in January, but the $44,000 base price is still a bit steep. If it proves to be a success, we will see more of them, and if not, then it'll go down as another failed experiment, like the 318ti hatchback.

BMW replaces tri-turbo diesel with a quad turbo

Quad turbos have until now been the stuff of Bugattis. BMW is introducing a quad turbo diesel for the 7 Series, with nearly one hundred horsepower per turbo. It's all about making the six-cylinder 3.0-liter turbodiesel all as enticing a proposition as possible, and it faces strong competition from Audi's new twin-turbo V8 diesel available in the SQ7 TDI. The earlier, N57S engine (pictured above) utilized a triple-turbo setup good for 381 horsepower and 546 lb-ft. The new B57 version, confirmed by BMW at the 37th International Vienna Motor Symposium, adds yet another turbo for 394 hp and 561 lb-ft, and that massive torque is available from 2,000 to 3,000 rpm. It means the 7 Series gets from 0-60 mph in a snappy 4.5 seconds. The engine could produce even more torque, but 561 lb-ft is all the ZF 8HP 8-speed automatic transmission can handle. The N57S engine's dual-stage turbocharging setup consisted of one low-pressure turbocharger to take care of low-end torque, and two high-pressure turbos for the higher rev range. In the new B57 engine, the big turbo is now replaced with two smaller units on a common exhaust, to benefit from lower costs and smaller unit weight. In addition to the gains in power and torque, fuel economy has reportedly been improved by 5 percent. There are no reports yet whether the B57 TOP quad-turbo will make it to the US market, but customers in the European high end diesel saloon market will probably be very excited. Initially it will be available in the 750d xDrive version, and other top-end models like the 5 Series and the X5 will follow later on.
