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's new 1,000-hp hybrid pulls like a freight train

Audi's latest plug-in hybrid handles like it's on rails, and pulls like a freight train. That's because it's a train, and literally rides on rails. The vehicle in question is a locomotive which the German automaker developed for its main factory in Ingolstadt incorporates over 11 miles of railroad tracks, along which are transported parts and completed vehicles to be moved around the site. To carry out those duties, Audi teamed up with French manufacturer Alston to deploy a new hybrid locomotive on premises. The locomotive features a plug-in hybrid propulsion systems capable of running on electric power alone for two hours at a time, and can be plugged in to recharge during down-time. The upshot is that it not only pollutes less overall, but can be run inside warehouses more safely. When the power runs out, the electrical system is backed up by a diesel engine. Audi reports that 15 trains arrive at the factory every day. It employs 17 locomotive drivers on site. And each locomotive runs for 3,800 hours each year. Whether we can take Audi at its word when it comes to diesel emissions or not, the company claims that the new hybrid locomotive cuts its carbon emissions by half, taking 60 tons of CO2 out of the atmosphere each year. 10/30/15 Ingolstadt Hybrid locomotive at Audi plant in Ingolstadt This Audi drives on rails: A 1,000 horsepower plug in hybrid locomotive manufactured by Alstom replaces the plant locomotives previously used at the Audi plant in Ingolstadt as of today. This means that components and finished Audi models will now reach the plant's loading stations in a more climate friendly way. "Our goal is all-round sustainable logistics," stated Johann Schmid, head of the Audi plant railway in Ingolstadt. "The new railway technology allows more economical, energy-efficient and low-emission rail transport. In connection with the latest chassis technology, the plug-in-hybrid locomotive sets new standards in shunting and rail transport." The complete automobile plant in Ingolstadt includes 18 kilometers of railways. Every day, 15 goods trains arrive at Ingolstadt North railway station for Audi – loaded with pressed parts, engines and transmissions, as well as cars from other Audi sites that are ready for delivery to customers. And cars produced in Ingolstadt also start their journey to customers by rail. 17 Audi locomotive drivers work at the plant railway. One of their tasks is to allocate the wagons to the various plant buildings.
