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..

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.

Car Club USA: CleanMPG Northwest Rally

Car Club USA heads to Los Angeles for the CleanMPG Northwest Rally, where a group of like-minded hypermiling enthusiasts led by Wayne Gerdes attempts to drive from Los Angeles, CA, to Bend, OR, on one tank of fuel. For this challenge, Wayne tapped some of the most accomplished hypermilers in the world, including Guinness World Record holder Bob Winger and Mike Sefton, "the most fuel efficient driver in all of Canada." It doesn't take long for the competition to get heated. "They're not aggressive enough, and it's not going to save them anything by being soft right now," says Gerdes as the group attempts to navigate the Interstate traffic. "Driving in Los Angeles is a hyper miler's nightmare," says Winger. The trip will challenge both car and driver, while putting the latest fuel-efficient tech to the test. Wayne is piloting the Volkswagen Golf Sportwagen TDI, Sefton drives the Audi A3 TDI, and Winger attempts the trek in a Honda Accord Hybrid. It's diesel versus hybrid tech on this fuel-efficient trip of a lifetime. Each Car Club USA episode features a different car club or event from across the US, where passionate owner communities gather to share automotive experiences and embark on incredible adventures.
