Electric turbos promise big performance and efficiency gains in the near future

An electric turbo system boosts efficiency between 15 and 20 percent, according to Audi.
Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.

2017 Audi S5 First Drive

Let's start with the obvious elephant in the room: The new 2017 Audi S5 looks mostly like the model it replaces. Is that a bad thing? We headed to Portugal to test out the S5 on that country's serpentine back roads, and to see if there's something more substantive behind its evolved exterior. Only compared to the decidedly more evocative Mercedes-AMG C43 Coupe does the svelte S5 come across as a little frumpy. It takes parking the new S5 next to the old one to spot the details. A tweaked profile. A more pronounced belt line. A power-dome hood. Narrower A-pillars. The new S5 is different, but the same, in that grand Audi tradition. Underhood, the differences are again evolutionary. The original S5 featured a 4.2-liter, naturally aspirated V8. A few years back, that was replaced by a supercharged 3.0-liter V6, which in turn has been supplanted in the 2017 S5 by a turbocharged 3.0-liter V6. The turbo, a twin-scroll unit nestled between the cylinder banks, helps the direct-injection engine make a healthy 354 horsepower and 369 pound-feet of torque. That power, 21 hp and 44 lb-ft more than its predecessor, is channelled through Quattro all-wheel drive. The newly developed V6 mates exclusively to a conventional eight-speed automatic, which seems like a step backward. Last year's S5 offered either a six-speed manual or a seven-speed dual-clutch gearbox. We pressed Audi and got the answer we expected: Demand for the stick was nonexistent outside the United States (go America!) and the dual-clutch couldn't handle the 44 pound-foot increase in torque. Curiously, the A5 on which the S5 is based trades last year's eight-speed autobox for a seven-speed dual-clutch. It sounds like someone at Audi put the wrong transmission in each car, but in reality the S5's torquey engine is well-suited to the refined eight-speed. Kick the throttle, get into boost, and all four drive wheels scrabble for traction, especially on the wet pavement we encountered outside of Porto, Portugal. Punch the S5 to pass on a tight two-lane road and the sport exhaust roars with the kind of guttural growl we want to hear in a sporty coupe. It positively scoots. Though its Volkswagen MLB 2 platform is new, the S5 rides and handles like a more refined version of its predecessor. Considerably less road rumble penetrates the cabin, and the S5 strikes a pleasant balance between grand-touring plush and sports-car firm.

Audi joins the car-sharing party with Shared Fleet

Seeing the success Zipcar and Daimler's Car2Go, more auto manufacturers are cutting out the middleman and jumping into the car sharing business. General Motors, Ford, and BMW have all introduced or announced their own programs. And now Audi has now thrown their hat into the ring with its Shared Fleet program. Like its competitors, Shared Fleet will be accessed through an app. The fleet consists of a mere three all-new and fully loaded 2017 Audi A4s and will be rolled out in a small pilot program in Durham, North Carolina. Audi plans a nationwide fleet for sometime in 2017. Through the app, customers will be able to locate and unlock vehicles. Pricing is currently unknown, but it is likely to be based off the time used, not the distance driven. The pilot program will be based at American Underground, a technology incubator in North Carolina. This will give Audi the chance to get the program into the hands of tech savvy users who have likely used competing programs. More than 700 employees at 200 companies are based at the facility. This isn't Audi's first foray into the car rental business. They previously invested a large amount into Silvercar. They also operate Audi on Demand in San Francisco, a similar program to Shared Fleet. With Audi on Demand, users can drop cars off at their destinations. Related Video:
