Next Audi RS4 to get an electric turbo?

We don't yet know if the next Audi RS4 will come to the US, but whoever gets it could find an electric turbocharger under the hood according to a report in Auto Express. The 4.2-liter V8 that has served for two RS4 generations is retiring from the line, replaced by a twin-turbocharged version of the supercharged 3.0-liter V6 used in the S4. But instead of using two sequential turbochargers - a smaller one to eliminate lag while a larger, more powerful turbo spools up - batteries charged by brake regeneration could power a first-stage electric turbo. The idea hasn't been publicly appointed for a particular model, as Audi's technical chief Ulrich Hackerberg has said that due to expense, that kind of setup "would only be used be used on the very top end models." Since the technology cuts down on the use of exhaust gases, it would also also help in markets like Europe where CO2 emissions are a factor. No matter whether it benefits from all conventional or some electric boost, the horsepower number for the twin-turbo V6 will be more than 420 hp but less than 503 hp, the rating of the V8-powered Mercedes-Benz C63 AMG. Auto Express believes Audi will want to maintain the power gap between the 333-hp S4 and previous, 444-hp RS4. With Hackenberg saying the new S4 will make more than 350 hp, that gets the coming RS4 up to at least 461, but AE figures it "could deliver as much as 480 hp." We'll find out sometime after the S4 launches next year.

KTM X-Bow to get Audi TT-RS five-cylinder turbo

The Audi TT-RS continues to occupy a warm spot in my personal top five list of cars thanks in no small part to the lusty turbocharged 2.5-liter five cylinder under the hood. With 360 horsepower and 343 pound-feet of torque in stock configuration, the engine is a shining star of internal combustion. And now it's headed to one of our favorite vehicles. EVO reports KTM is planning to plop the turbo 2.5 from the TT-RS into the upcoming X-Bow. That ruckus you hear? It's a choir of angels singing "Halleluiah." While speaking at the Geneva Motor Show, KTM CEO Stefan Pierer said the engine is good for up to 480 horsepower.
Pierer went on to say that the company is already testing prototypes and that we may very well see the engine show up in some races next year. What's more, the company's engineers are playing with dual-clutch transmissions, too. Since KTM is already testing the turbo 2.5 on the track, it's only a matter of time before customers will be able to get their grubby mitts on a street-legal version.

2015 Audi R8 Competition ready to rock LA

The heyday of the first-generation Audi R8 is winding down, and the Four Rings already has a bespoke factory to start building the next model soon. In the meantime, the German brand is sending its supercar off with a bang at the 2014 Los Angeles Auto Show in the form of this limited-edition 2015 R8 Competition - the most powerful production vehicle ever made by the company.
Audi is earmarking just 60 examples of the Competition for the US, and this is more than just a trim package to say farewell. Power for the supercar comes from the usual 5.2-liter V10 that's massaged to develop 570 horsepower, an extra 20 hp over the already quite potent V10 Plus, and the only available transmission is the seven-speed, dual clutch S Tronic gearbox. The tweaks let this limited R8 rocket to 60 miles per hour in 3.2 seconds and achieve a maximum velocity of 199 mph. To haul that speed to a stop, it also gets ceramic brake disks with red calipers.
Of course, having such a rare supercar means showing off a little. Audi takes inspiration from the R8 LMS Ultra racecar for the Competition and tries to bring some of its details to the street. The model wears matte carbon fiber pieces replacing the rear spoiler, mirror housings, side blades, front spoiler and rear diffuser. For an extra mean-looking touch, it also has high-gloss black paint covering the wheels and exhaust pipes.
