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.

NHTSA expands new Takata probe to 4 more automakers

DETROIT — The U.S. government's highway safety agency has launched an investigation into four additional automakers that have a potentially deadly type of Takata air bag inflator in their vehicles but have yet to recall them. The National Highway Traffic Safety Administration said in documents posted Thursday that it is investigating Audi, Toyota, Honda and Mitsubishi in connection with a Takata recall involving 1.4 million inflators. This brings the total number of manufacturers potentially impacted to five, as BMW was connected to the issue when it was brought to light earlier in December. The inflators made by the now-bankrupt Takata have a distinct and separate problem that can cause them to blow apart a metal canister and spew shrapnel into people's faces and bodies. The problem killed a driver in Australia who was in an older 3-Series BMW, which has already recalled more than 116,000 vehicles. The problem is so dangerous that in some cases BMW has told drivers to park their vehicles until repairs can be made. The safety agency says in documents that Takata didn't provide details on the affected makes, models or model years of vehicles with the defective inflators. So it is telling the companies to recall them promptly. The agency says that based on when the faulty inflators were produced, it's likely that the vehicles to be recalled came from the 1995 through 2000 model years. In letters to all four automakers, NHTSA says they have five business days to notify the agency after finding out about a safety defect. “If your company has not yet gathered enough evidence to make a determination that the subject air bag inflators present an unreasonable risk to motor vehicle safety, reply with a detailed work plan including the benchmark dates required to make the determination,” the agency wrote in letters to all four automakers dated Wednesday. A Honda spokesman said Thursday it hasn't determined yet whether its vehicles are affected, but a decision should be made soon. Audi, Mitsubishi and Toyota said they are still investigating. NHTSA has told the companies to respond by Jan. 17. On Dec. 4, NHTSA posted documents from Takata and BMW detailing the problems. The documents said the Australian driver was killed, while another Australian driver and a driver in Cyprus were injured. Unlike previous recalls, the Takata non-azide inflators do not use volatile ammonium nitrate to fill the air bags in a crash.

Audi buys Ballard fuel cell patents for $80 million

While some auto companies (e.g., Toyota and Hyundai) are giving away some hydrogen fuel cell patents, others are paying a pretty penny to gain access to the H2 tech. Audi announced today that it has purchased a suite of fuel-cell patent from Ballard Power Systems. The deal between Volkswagen Group and the Canadian fuel cell pioneer is worth over $80 million US. Unsurprisingly, the value of Ballard's stock shot up about a dollar (to $2.61 as of this writing) on the announcement. VW and Ballard will also extend their development agreement, originally scheduled to end in 2017, to March 2019, and possibly another two years after that. Thus far, the deal – which revolves around the "design and manufacture of next-generation fuel cell stacks" for VW's H2 demonstration program – and Ballard says it is a leader in "critical areas of fuel cell product design – including the membrane electrode assembly (MEA), plate and stack components – along with certain testing and integration work." At the LA Auto Show last fall, VW showed off a Golf SportWagen and a Passat with a hydrogen hybrid HyMotion powertrain as well as a Audi A7 Sportback H-Tron Quattro. Audi buys fuel-cell patents from Ballard Power Systems Development agreement with Ballard extended until 2019 Audi's Head of Development Prof. Hackenberg: "The entire VW Group will use these patents." Ingolstadt/Burnaby, February 11, 2015 – AUDI AG has acquired a package of patents relating to fuel-cell technology from Ballard Power Systems Inc. In addition, the Volkswagen Group has extended its cooperation with the Canadian clean energy company until 2019. The purchase of these patents will provide new impetus for the development of fuel-cell drive systems at Audi, VW and the Volkswagen Group. As explained by Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at AUDI AG and responsible for the steering of the development departments of all brands in the VW Group: "Audi is acquiring these strategically important patents for the entire group and will make them available to all the brands. In this way, we are securing crucial expertise that will provide new impetus for the further development of this technology." Ballard Power Systems Inc. is based in Burnaby, Canada, and is one of the world's leading companies in the technology of proton exchange membrane fuel cells.
