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 readying impressive track-focused M Power App

There are a lot of questionable automotive apps that people put on their smartphones these days, but BMW has created what could be one of the most useful and integrated car apps ever. The new M Power App, which will be available this summer only for Apple iPhones, allows BMW owners a whole new way to record their performance on the street or on a track. During the launch of the recent BMW M6 Gran Coupe, BimmerPost was able to get a full demonstration of how this new app works.
Far more involved than the current M Power Meter, the M Power App records data from in-car sensors and acts as a telemetry tool to allow drivers to see how they did on a particular track. Aside from an overlay on a track map showing acceleration and braking applications as well as head-to-head comparisons, the app also shows a line graph of everything from brake and throttle inputs to g-force, fuel mileage and engine speed. A small visual on the screen also shows steering angle, and lap times and speeds can all be stored as well. The data can even be shared with others, whether for bragging rights or instruction purposes.
This app works on any newer BMW equipped with the BMW Apps option, but the phone must be tethered to the car and the data understandably cannot be viewed while driving. Scroll down for the video demonstration recorded recently at Austin's Circuit of the Americas.

BMW to change model designations, further yet from actual displacement?

Once upon a time, you could look at the back of a trunk lid of a BMW and come up with a pretty fair idea of what sat under its hood. For example, a 320i was a 3 Series with a fuel-injected, 2.0-liter engine, a 328i was a 3 Series with a fuel-injected, 2.8-liter engine and a 328Ci was a two-door 3 Series with the same engine. Those were good days.
Today, though, that simplicity is dead and gone. A 328i now has a 2.0-liter engine, just like the 320i, while the simple "C" designation that was affixed to two-door models has been replaced with a "4," so we have a 428i and a 435i. It gets worse, though. A 550i uses a 4.4-liter, twin-turbocharged V8 (it should be a 544ti, although we'd be willing to hear an argument for "tti") and a 740i uses a 3.0-liter, turbocharged six-cylinder, which is the same engine found in a 535i. It's madness.
And, well, it's about to get madder, if a post on a BMW enthusiast forum is to be believed. According to f30post.com, we could see a shakeup in at least the 3 and 4 Series nomenclature, thanks to an impending refresh that will see the addition of new, turbocharged four- and six-cylinder engines, codenamed B48 and B58, respectively.
