2018 Audi SQ5 will use 48-volt electric supercharger

It seems like 48-volt electric systems and electric compressors are becoming relatively mainstream, and Audi will be adding another vehicle powered by this emerging technology in 2017, according to comments Audi powertrain chief Oliver Hoffman made to Autocar. Hoffman said the upcoming SQ5, probably a 2018-model-year vehicle, will use a version of the electric compressor technology that debuted on the SQ7. While the SQ7 uses two gas-driven turbochargers and one electric compressor, the SQ5 will likely only use one conventional turbo and one e-compressor. That should allow it to make 365 hp, but 390 hp is possible from the system and may hint at room for a more powerful SQ5 Plus down the road. Remember, the European SQ5 uses a 3.0-liter TDI engine, and that's the same basic engine that will power the new SQ5 with the addition of the new forced induction system and 48-volt electrics. And also remember that the US-market SQ5 uses a supercharged 3.0-liter gasoline engine, not the TDI unit, which is one of the reasons it's still on sale in the wake of the TDI scandal. Torque is the real differentiator: the current US-market SQ5 makes 354 hp and 347 lb-ft of torque, while the current Euro-market SQ5 Plus makes a massive 516 lb-ft. No word yet on how the dual-compressor system on the upcoming SQ5 will affect torque numbers, but expect the new engine to again have considerably more twist than its gas-powered US-market counterpart.

Audi TT Quattro Sport Concept takes the next-gen to the extreme

There's little doubt that the new Audi TTS and its 310-horsepower, 2.0-liter, turbocharged four-cylinder will be very quick when released to the general public. As a means of reminding us that Audi can do much more with the little TT, though, the German manufacturer has presented this, the TT Quattro Sport Concept, alongside its litter of new sports cars.
Complete with a 420-horsepower, 2.0-liter, turbocharged engine - yes, it really puts out 210 horsepower per liter - the TT Quattro Sport can snap to 62 miles per hour in just 3.7 seconds. 331 pound-feet of torque is also on offer, meaning this one-off TT outguns the TTS by 110 horsepower and 51 pound-feet of torque.
An S-Tronic transmission shuffles the power about, while the car itself rides on a lowered and stiffened suspension. 20-inch alloys are featured with centrally locking, racing-style hubs. Those racy wheels are housed in wells that have had their arches stretched an additional 1.18 inches, which, along with the lowered suspension, contribute to the TT's aggressive looks.

Audi may add plug-in hybrid A6, A8 and Q7 to range [w/poll]

Audi could be getting even more diverse with its powertrains for the A6, A8 and Q7, moving beyond offering just gas- and diesel-powered models and adding plug-in hybrid variants of the three luxury vehicles. The report comes from Indian Autos Blog, which spoke to Dr. Ulrich Hackenberg, Audi's research and design chief, who confirmed the PHVs.
The next-generation Q7, due in 2015, will be the pioneer for the full-size PHV movement from Audi, although the A3 Sportback E-Tron (shown above) will precede it. The move toward plug-ins by Audi is a big step, as the German marque has stayed quite firmly in the diesel camp, outside of its racing efforts. It's developed a few E-Tron cars over the years, including a version based on the R8, although it wasn't until recently that production of the electric sports car became serious again.
It's believed that this hesitance to really dive into the PHV market is why Audi sacked former research and design boss Wolfgan Dürheimer, with IAB speculating that his approach was too conservative.
