2014 Audi Q5 TDI

I've struggled with diesel technology. It's not that I have a problem with it or dislike it, but rather that I don't particularly understand what stops its wider-spread adoption. Sure, memories of rust-prone, smoky, sluggish and uneconomical Oldsmobile diesels aren't exactly easy to erase from the collective memory of the North American motoring public, but I'd think that a few years into the latest crop of clean diesels, there'd be wider adoption - or at least consumer consideration - by now.
Part of the issue is the still limited number of segments that diesels are available in. The Volkswagen Golf/Jetta TDI is finally getting a challenger in the form of the Chevrolet Cruze Diesel, and the BMW 328d is bringing something new to the entry-level sports sedan, but there are still a huge group of segments where diesel-power has no representation.
The small, luxury crossover realm is not one of those. It has the Mercedes-Benz GLK250 Bluetec, a stylish crossover with a silky-smooth 2.1-liter, turbodiesel four-cylinder that can return the kind of fuel economy that makes people take notice. And while the GLK250 is quite good, economy will only spread the diesel's appeal so far. People need to experience the seat-flattening torque that these mills can produce, and for that, we most humbly recommend the new 2014 Audi Q5 TDI.

Translogic 164: Driving the fuel cell vehicles of the 2014 LA Auto Show

The LA Auto Show is known for its environmentally friendly vehicle debuts. At last year's show, hydrogen fuel cell concepts from Honda and Toyota joined a lease-ready Hyundai Tucson FCEV to cast a green hue over the convention center. This year, automakers took us a step closer to a fuel cell future by offering drives of their hydrogen-electric hybrids. Translogic host Jonathon Buckley takes a ride in the Toyota Mirai, which is headed for production in 2016. He follows that with a spin in the Volkswagen Passat HyMotion and the Audi A7 Sportback h-tron quattro concept. Which of these fuel cell vehicles holds the most promise? Tune in to find out.

Audi builds 5-millionth vehicle with Quattro

Quattro, the trademark name Audi has put on its all-wheel-drive system engineered for passenger vehicles, recently celebrated its five-millionth installation. The driveline has been offered in more than 140 different vehicles since its introduction more than three decades ago.
The all-wheel-drive technology made its world debut at the 1980 International Geneva Motor Show, beneath the floorpan of the Quattro Coupé, a low-volume two-door. It didn't take consumers long to embrace Audi's innovative approach. While most four-wheel-drive systems at that time utilized heavy transfer cases or second cardan shafts, Quattro was virtually tension-free, light, compact and efficient. Most importantly, enthusiasts found it was especially suitable for sports cars.
Today, the automaker offers Quattro on its full line of passenger vehicles and it is unquestionably successful (the technology enjoyed a 43 percent take rate in 2012). On models with transverse-mounted engines (A3 and TT), Audi uses an electronically controlled multi-plate clutch with hydraulic actuator. Under normal conditions, the clutch sends power almost exclusively to the front wheels (if wheel slippage occurs, up to 100 percent of the torque may be sent to the rear). Vehicles with transverse-mounted engines (A4, A5, Q5, etc...) use a self-locking center differential sending 40 percent of the engine torque to the front axle and 60 percent to the rear under normal conditions (it is able to send the majority of the power to the axle with better traction when needed). The highest-performing Quattro systems use torque vectoring to further improve cornering grip and speeds.
