Audi exec denies plans for turbo R8

Sometimes smoke doesn't lead to fire. Rumors indicated Audi might drop a turbocharged engine into the latest R8, but now a top executive is throwing a bucket of cold water onto the burning speculation. "The performance potential of this current engine means we don't need to even look at turbocharging at this point," Jurgen Konigstedt, Audi development boss for V6, V8, and V10 engines, said to CarAdvice. He also said sticking with natural aspiration offered a better sound and sharper throttle response than going with forced induction. "There is less emotion with a turbocharged engine," he said. Konigstedt admitted there was a serious discussion about turbocharging the R8. The argument just didn't win out. "If we feel that people absolutely want a turbocharged engine, then we will have to consider it," he said to CarAdvice. Audi just launched a new generation of the supercar. The 2017 R8's 5.2-liter V10 will be available in two tunes: with 540 horsepower in the standard coupe or 610 hp in the Plus. Rumors have persisted about a smaller, forced induction powerplant at the bottom of the range. Some reports suggested a twin-turbo V6 behind the driver, but others said the electrically supercharged 2.5-liter inline five was a candidate. The reason for the entry-level addition was tied to lowering the taxes on the R8 in markets like China. Related Video:

Audi says new 48 volt micro-hybrid system improves fuel economy, paves way for electrification

Most cars use a 12-volt system to power their electrical components. But, with more and more electric bits and bobs being added to new vehicles, a dozen volts is looking a bit weak these days. In fact, Audi says that standard 12-volt systems are being stretched "to their very limits." Enter 48 volts. If used in a car that gets 40 mpg, that would translate to around 43.5 mpg. Audi is testing a supplemental 48-volt electric system in two prototype vehicles – modified mild-hybrid versions of the A6 TDI and the RS 5 TDI – in order to add in more electric technology (an electric compressor, for example, to improve acceleration) and "convenience systems for dynamic chassis control." Audi says it has more applications in the pipeline, but the overall gist is that the German automaker sees 48 volts as an "important building block in electrification strategy." As you can see in the picture above (click to enlarge), the RS 5 TDI concept uses a li-ion battery installed in the back of the car and an alternator to provide 48 volts when the engine is off. Audi says that the 48-volt system can save up to 0.4 liters of fuel per 100 kilometers. To put that into US numbers, if used in a car that gets 40 miles per gallon today, that would translate into a bump up to around 43.5 mpg. The Advanced Lead Acid Battery Consortium (ALABC) is also working on a 48-volt system to improve fuel economy and we've got a deep dive of Audi's electric turbocharger here. Even more powerful and efficient – the new 48-volt technology from Audi Important building block in electrification strategy More voltage and more power for new technologies Scalable platform concept suitable for wide-ranging uses Ingolstadt, August 25, 2014 – Audi is to upgrade part of its vehicle electrical system from twelve to 48 volts. The move represents another technical building block for facilitating the integration of new automotive technologies while increasing the power and efficiency of its cars. "We are using the full bandwidth of electrification in our drive principles strategy. Running part of the vehicle electrical system at 48 volts plays a central role in this," commented Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at Audi. "It enables us to make more energy available.

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.
