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.

Audi reveals S3 Cabriolet ahead of Geneva debut

It used to be if you wanted an Audi S3, your choices in bodystyle came down to hatchback or... hatchback. That is, in markets where the model was offered at all. But Audi has been expanding the A3 global family upon which the S3 is based, and it intends to offer the performance-minded derivative as a three-door hatch, five-door hatch, four-door sedan and - with the introduction of the version you see here - a two-door convertible.
Set to be presented in public for the first time at the Geneva Motor Show early next month, the new Audi S3 Cabriolet packs the same 2.0-liter turbo four as its fixed-roof counterparts - all 290 horsepower and 280 pound-feet of it - but ditches the extra doors and the tin top in favor of the two-door cabriolet bodystyle of the A3 Cabriolet.
The added weight of the folding fabric roof mechanism and the extra body reinforcement required means that the S3 cabrio takes half a second more to reach 62 miles per hour from a standstill than it would take the sedan version, clocking the run at 5.4 seconds instead of 4.9. This, despite more generous use of magnesium, aluminum and high-strength steel in its construction. Top speed, as is the German custom, remains pinned at 155 mph.

The 2018 Audi RS3 sedan priced above the BMW M2 and Mercedes CLA45 AMG

Today, Audi finally released pricing for the 2018 RS3 sedan and it's not quite the performance bargain you may have been hoping for. The RS3 sedan, available for the first time in the US, will start at $55,875 when it hits dealer lots later this year. That's thousands more than the competition from BMW and Mercedes-Benz, though it's not quite a straight one-to-one comparison. View 23 Photos For reference, a BMW M2 starts at $53,495 while a Mercedes-Benz CLA45 AMG will set you back at least $50,875. With an all-new 400 horsepower inline-5 under the hood, the RS3 is packing more punch than its German rivals, and, unlike the M2, sends power to all four wheels. Standard features include LED lighting, Audi pre sense basic, and blind-spot monitoring. Other standard equipment hasn't been announced yet, so it's difficult to make a straight comparison to the M2 and CLA45 AMG. The RS3 sedan will make its North American debut next week in New York. While the car will hit full production for the 2018 model year, there will be a limited number of 2017 RS3s produced. At $55,450, the 2017 model is slightly less expensive than the 2018 RS3. That small batch will be preconfigured with carbon trim, Audi virtual cockpit with MMI Navigation plus, a Bang & Olufsen sound system, 19-inch, five-arm-blade design wheels, red brake calipers, and the RS sport exhaust system with black tips. Sounds like a good deal if you've already got your heart set on the latest from Audi Sport. Related Video:
