Audi debuts all-new R18 E-Tron Quattro with novel secondary hybrid system

This is the new Audi R18. It looks like the Bond villain of race cars (it has red running lamps), and if Audi's past is any indication, it'll prove difficult to beat in the LMP1 class of the 2014 World Endurance Championship.
The car's full name is the Audi R18 E-Tron Quattro, just like last year's car. Also like last year's car, the new R18 draws its power from a V6 turbodiesel, which powers its rear wheels, and Audi's E-Tron hybrid system, which runs its front axle. Unlike last year's car, though, this R18 has a secondary hybrid system. Audi has fitted the V6 with an electric turbocharger and figured out how to capture waste heat generated when the engine reaches its boost limit. That power can then be stored and fed back into either the turbo or the front axle's hybrid system under acceleration.
There are a number of changes to the body on the new car, forced in large part by series regulation changes. The car is narrower, particularly at the front, but it's also taller. The front end is set off by a new wing, as part of a new WEC regulation. Audi seems quite pleased about this, citing an improvement in front-end downforce and a reduction in cost. Like Formula One, the WEC contenders now have to contend with a ban on the so-called blown diffuser, which forced exhaust gases over the diffuser, creating downforce. That's necessitated some changes from Audi, although as we have no rear shots of the car, we can't tell you what it looks like.

2014 Audi RS7 is a 189-mph terror

If you have a burning desire to take yourself and four friends to 189 miles per hour, the 2014 Audi RS7 Sportback can help you out. The luxury hatchback bowed at the 2013 Detroit Auto Show today, complete with a 560-horsepower twin-turbocharged 4.0-liter V8 engine thrashing under the hood. Getting to 62 mph takes a shave under 3.9 seconds thanks in part to the 553 pound-feet of torque on hand from just 1,750 rpm. While the base car comes with an electronically limited top speed of 155 mph, customers can request the governor be removed by purchasing the dynamic package plus, upping the V-max to 189 mph.
Ludicrous? Sure, but Audi says the RS7 can also yield up to 25 mpg on the US scale. With a cylinder-on-demand system, the V8 can deactivate up to four cylinders by closing their valves. Once the driver gets frisky with the throttle, the engine automatically kicks from four-cylinder to eight-cylinder mode in a few hundredths of a second. The engine is bolted to an eight-speed automatic transmission, which pushes power to all four wheels. You can read the full press release below for more information, but we think you'll have a better time viewing our live shots from the show floor..

Next Audi R8 to eschew engine downsizing, go on diet instead

Looking across the Audi landscape, many models that used to get the company's high-revving, naturally aspirated 4.2-liter V8 are now powered by smaller, yet similarly powerful, forced-induction engines. From what Auto Express is reporting, though, the next-generation Audi R8 will not meet this same fate.
Rather than ditching its V8 and V10 powerplants, the next-gen R8 - expected to debut in 2015 - will shed pounds from its curb weight. The 2014 R8 currently weighs between 3,583 pounds and up to 3,957 pounds, but the report says that engineers are targeting a weight of less than 3,300 pounds. All models will get cylinder deactivation, which along with lower curb weights should help to improve fuel economy and emissions. Head on over to Auto Express for more reported information as well as a handful of renderings that take a stab at how the next R8 may look.
