US diesel model count to double for 2014?

While diesel cars are popular on most other continents, these less-complex alternative to hybrid-electric vehicles have yet to gain major traction in the US. As an increasing number of light cars and trucks start to offer these fuel-efficient engines, though, sales are expected to climb as well. While BMW, Mercedes-Benz and the Volkswagen Group (Volkswagen, Audi and Porsche) continue to lead the way, more non-German automakers like Mazda, Nissan, Chrysler and General Motors are starting to get serious about diesel in America.
TheDetroitBureau.com reports that the 2014 model year will see the number of diesel vehicles offered in the US double to about 40 nameplates, but the news gets even better for fans of these torquey and efficient powerplants. LMC Automotive has released data about future expectations of diesel cars in the US, and it predicts that sales should be very close to one million units in 2015 (up from an expected 600,000 units this year). By 2018, LMC's calculations suggest that sales will more than double from this year's expected totals accounting for almost 8 percent of new light-vehicle sales.

Dieselgate defeats Audi's Le Mans racing dynasty

Referring to what the automotive press has dubbed "Dieselgate", Audi's Chairman of the Board of Management Rupert Stadler announced that Audi is pulling out of the FIA World Endurance Championship by the end of the 2016 season. This means Audi will no longer compete in the 24 Hours of Le Mans. However, that doesn't mean Audi is through with competing on the world stage. Instead of fossil-fuel-powered prototype racing, Audi will now "focus on the things that will keep (it) competitive in the years ahead", namely Formula E. Having worked together previously with Audi tuner ABT and component manufacturer Schaeffler in Formula E, the company is now turning Team ABT Schaeffler Audi Sport into a fully factory-backed outfit. Audi's DTM efforts with the RS 5 DTM will remain untouched for the time being, and the company hasn't made a decision yet as to whether its World Rallycross Championship with the Audi S1 EKS RX quattro will continue. Audi has competed in Le Mans prototype racing for 18 years, during which it secured 13 Le Mans wins. Out of 185 races contested by Audi's LMP cars, they racked up an impressive 106 wins. Audi's victory in 2006 was the first with a TDI engine, and the first hybrid-engine win was claimed in 2012. From 2000 to 2008, Audi won nine consecutive American Le Mans Series titles.

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.
