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.

Alpina D3 Bi-Turbo torquing its way toward Frankfurt

Few tuners benefit from the kind of factory support that Alpina does, giving the pseudo-aftermarket firm nearly as much official status as BMW's own M division. And this is its latest product.
Set to debut, as expected, at the Frankfurt Motor Show this week is the new Alpina D3 Bi-Turbo, which you can consider, for all intents and purposes, the diesel M3 that BMW never built. While the outgoing D3 (which was Alpina's best-selling model) used a four-cylinder engine, Autocar reports that the new model packs a 3.0-liter, twin-turbo inline-six diesel to drive a respectable 345 horsepower but a mammoth 516 pound-feet of torque to either the rear wheels or all four through the optional availability of xDrive. (European buyers will also be able to choose between sedan and wagon bodystyles.)
The engine is the same as you'd find in the XD3 and D5 (Alpina's diesel performance versions of the X3 and 5 Series, respectively), but in the lighter 3 Series form can propel the D3 Bi-Turbo up to 62 miles per hour in 4.6 seconds and on to an Autobahn-crunching top speed of 173 mph. And as per Alpina tradition, visual cues are minimal, with a subtly optimized aero kit and 19- or available 20-inch alloy wheels. Unfortunately, the 7 Series-based B7 is the only Alpina we get on this side of the Atlantic, but an oil-drenched performance enthusiast can dream.

Evo pits BMW M3 against Porsche Macan in drag battle

If you want to move five passengers in very rapid fashion and you've got a $75,000 budget, two newly introduced four-door models immediately come to mind - both are the highest performing vehicles in their respective segments. But which is faster off the line, to the 60-mile-per-hour benchmark or flat-out over an even longer run? Evo took both to paved aircraft runway to find out.
In lane one we've got the all-new Porsche Macan Turbo, which boasts a twin-turbocharged, 3.6-liter V6 rated at 400 horsepower and 406 pound-feet of torque. The Porsche is fitted with a seven-speed, dual-clutch gearbox, and the 4,244-pound crossover has the traction advantage of standard all-wheel drive. In lane two is the all-new BMW M3, powered by a twin-turbo 3.0-liter inline-six rated at 425 horsepower and 406 pound-feet of torque. It is also equipped with a seven-speed, dual-clutch gearbox, but only the rear wheels of the 3,595-pound sedan are driven. Both the BMW and Porsche arrive with launch control, which helps to remove driver error off the line.
Which automaker's launch control system is better off the line? Does all-wheel-drive grip give the crossover the advantage it needs to overcome its adversary's power-to-weight advantage? Will aerodynamics factor into the results? Which would you put in your garage, and why? The video may surprise you.
