Five cylinders, no waiting | 2018 Audi TT RS First Drive

A five-cylinder engine is an odd duck in the modern automotive world, so why put it under the hood of a sophisticated sports car like the 2018 Audi TT RS? We're posing this question to an engineer when a loud, guttural sound interrupts the conversation. A TT RS blasts by, growling and percolating as it shoots down the front straight of the historic Circuito del Jarama in Spain. Oh, that's why. The RS treatment brings the sound and the fury to the TT, transforming a cute, sporty little car into a sports car with mettle. With 400 horsepower channeled to all four wheels, a stiffer suspension, and styling flourishes like organic LED taillights, the RS makes for a big-time upgrade over the 292-hp TT S and the mild-mannered 220-hp TT. Who wants a four-cylinder, anyway? We're considering the five-pot's potential as we mash the throttle and explode onto Jarama, an old Formula 1 course that still looks ready to host top-level racing. There's a couple of long straights and lots of curves and elevation changes. Sure, it's a bit trite to praise a sports car after a few laps in a controlled setting, but the TT RS has legit performance chops. The engine sounds just as good inside the car as it does to spectators, and it's more satisfying since we're the ones provoking the five cylinders to anger as we approach triple-digit speed. It's all real, too. There's no pumped-in sound or fake flatulent exhaust. "It's the unadulterated sound of the engine – we didn't change it," says Philipp Ade, Audi technical project manager for powertrain. Speaking trackside through an interpreter, he admits the exhaust system adds resonance but also filters out other noises to produce a clean engine note. Trust us, you'll want to tune in. The five-cylinder is not a glorified sound check. It's a new engine developed for Audi's smaller performance cars, though the TT RS is the only one confirmed for the United States. The 2.5-liter mill uses aluminum for its block and crankcase and magnesium for the oil sump. This all results in a 57-pound weight loss compared with the old five-cylinder, which was last sold in the US market in the previous-generation TT RS for the 2012-13 model years. That car was brought to the states after a Facebook campaign. This time there was no doubt Americans have an appetite for the hottest TT. A non-enthusiast will wonder: why the fuss over a five-cylinder engine? To Audi and its band of loyal followers, it's a defining element of performance.

Porsche takes 2016 Le Mans win on last lap, Ford grabs class victory

So far, only one Japanese manufacturer has won the 24 Hours of Le Mans endurance race. That carmaker was Mazda exactly 25 years ago with the legendary, rotary-engined 787B. This year, Toyota was amazingly close to winning with their TS 050 car, piloted by Kazuki Nakajima, and it all ended in tears on the last lap. The Toyota ran smoothly for almost 24 hours, but to lose power and stall on the pit straight with five minutes to go is nothing short of catastrophic. Still, the #5 car was able to be restarted and limped across the finish line for 45th place. Toyota's #6 car had its own set of issues, as the car gained bodywork damage and also veered off track in the hands of Kamui Kobayashi. Driven to second place, the Toyota #6 passed the finish line driven by Stephane Sarrazin. For Porsche, the win with the #2 919 Hybrid was the 18th constructor title at Le Mans 24 Hours. The car was driven by Romain Dumas, Neel Jani and Marc Lieb, and it proved to be more reliable than the #1 919 with Timo Bernhard, Mark Webber and Brendon Hartley behind the wheel. The #2 Porsche and the #5 Toyota battled for the lead throughout the day. Had the Toyota not broken down, Audi would have missed a podium finish for the first time in 18 years - a great run was ruined this year by turbo trouble in the #7 R18 e-tron Quattro driven by Lotterer-Treluyer-Fassler, and the third place was taken by the #8 Audi with Lucas Di Grassi driving.

Audi moves to patent electric Quattro and active-shutter wheels

Audi might have a few tricks up its sleeve for the coming years, with the Brits at Autocar uncovering a pair of patent filings made by the German luxury brand. The first is something we've seen before - wheel flaps - while the second is an evolution of one of Audi's trademark technologies.
We last saw wheel flaps on the Ford Atlas Concept in 2013, but the futuristic fuel-saving tech has so far failed to arrive on a production car. Audi may be seeking to change that, patenting the flaps that open and close automagically based on airflow. They can also open if the brakes get too hot.
The second patent is an evolution of Audi's Quattro all-wheel drive. The new AWD system uses an electrically driven rear axle and wheel sensors to figure out when and at which corner the car might lose traction, and is targeted largely at hybrid offerings, which is a field Audi has only recently dipped its toe into.
