Audi to abandon CVTs?

The continuously variable transmission is one of those technologies that seems to make a lot of sense on paper, but in reality, almost always numbs the driving experience. That's one reason why Audi, according to reports, is planning to phase them out.
One of the first automakers to implement use of the CVT, Audi mates CVTs to larger engines than many other manufacturers, which typically install them on scooters, hybrids and small-displacement hatchbacks. But the time of the Audi CVT (which it calls Multimatic) may be near its end as a report from Australia indicates that Ingolstadt is moving toward a two-gearbox lineup that does not include the rubber-band transmission.
Instead, Audi is said to be focusing its attention on the S-tronic dual-clutch transmission and on conventional torque-converter automatics - although the development of beefier DCTs could spell the end of the Audi slushbox, as well. We've reached out to Audi for comment, so watch this space for confirmation.

Audi A7 Sportback H-Tron Quattro packs plug-in hydrogen powertrain

If you think a plug-in diesel hybrid is an expensive proposition, just wait until you hear details about the just-revealed Audi A7 Sportback H-Tron Quattro. The "H" in H-Tron, as you might guess, stands for hydrogen, so say hello to a new concept that combines a plug-in battery system with a hydrogen fuel cell. Yeah, exactly. Let's start with the numbers. On the plug-in side, the new H-Tron has an 8.8-kWh lithium-ion battery that can power the car for up to 31 miles on battery power. With electric motors on both axles – it's a Quattro, after all, but a through-the-road hybrid with electronic torque distribution management – the A7 H-Tron uses a hydrogen fuel cell and four (!) H2 tanks to offer about 62 miles per gallon equivalent. Audi says the overall fuel cell stack efficiency is "as high as 60 percent" while the electric motors operate at 95 percent efficiency. Efficiently turning all of that electricity into movement means the A7 Sportback H-Tron Quattro has a total power output of 398.3 pound-feet of torque. The 4,299-pound concept can allegedly go from 0-62 miles per hour in 7.9 seconds and has a top speed of 112 mph. The car's total range is 311 miles. The A7 H-Tron is not the first plug-in hydrogen vehicle concept. That title goes to the Ford HySeries Edge. Mazda also considered putting a hydrogen range extender in the Mazda5 plug-in van. The Audi A7 Sportback h-tron quattro It sprints from 0 to 100 km/h (62.1 mi) in 7.9 seconds and on to a top speed of 180 km/h (111.8 mph). It covers over 500 kilometers (310.7 mi) on one tank of fuel – and its exhaust emits nothing more than a few drops of water: The A7 Sportback h-tron quattro, which Audi is unveiling at the Los Angeles Auto Show 2014, uses a powerful, sporty electric drive with a fuel cell as its energy source that operates in combination with a hybrid battery and an additional electric motor in the rear. The overall electrical system power of 170 kW is transferred to both the front and the rear wheels. This drive configuration makes the emission-free Audi A7 Sportback* a quattro through and through – a new departure in fuel cell cars. "The A7 Sportback h-tron quattro is a genuine Audi – at once sporty and efficient. Conceived as an e-quattro, its two electric motors drive all four wheels," explained Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at Audi. "The h-tron concept car shows that we have mastered fuel cell technology.

New Audi R8 Spyder V10 Plus is a topless brute

If the "normal" 540-horsepower R8 Spyder isn't doing it for you, the wait is over. Audi has upped its convertible, mid-engined Huracan sibling to Plus spec, which means the FSI V10 gets a whopping 70-horsepower bump, all the way up to 610. Plus, like its lowlier sibling, you get a power folding soft top that goes up or down at up to 31 mph. But wait, there's more! The normal R8 Spyder can hit 60 miles per hour in just 3.5 seconds, according to the manufacturer, while the new one will hit 62 mph in 3.3 seconds. (Since the first specs we have are for the European version, we get 0-100 km times rather than 0-60 mph times. It's clear the V10 Plus is notably quicker.) No matter where you buy one, each V10 Plus will rev out to 8,700 rpm. Top speed increases slightly, to 203.8 mph – much faster than you'd want to go with the top down, surely. The rest of the powertrain is standard R8. There's a seven-speed S-tronic dual-clutch gearbox, the only transmission available, and Quattro all-wheel drive standard. Like the standard R8, it can send up to 100 percent of its power to either axle in extreme situations, and there's a rear differential locker for added traction. While a variable-assist steering rack is an option, the standard steering box is an electromechanical unit. Inside and out, there's a lot of exotic stuff. Optional Audi laser headlights and standard Audi virtual cockpit tick the box for Euro technophiles, while diehard Audi Sport enthusiasts will appreciate the carbon fiber diffuser that adds up to 220 pounds of downforce to the package. Speaking of pounds, that top weighs 97 pounds, but the total package weighs 55 less than the regular R8 Spyder. That weight savings is due to lightweight bucket seats, carbon ceramic brakes (15 inches up front, 14 in the back), and lighter alloy wheels. The cars will be delivered in Europe in late summer. We'll know more about US-market cars soon, surely.
