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.

Get lost in Evo's sublime 2013 Car of the Year testing

Every year Evo stages its Car of the Year test, bringing the best performance cars in the world to one location for an epic shootout. This year the magazine pitted eight CotY finalists against each other on Route Napoleon in Southern France - Evo claims it's the "best road in the world" - and then proceeded to nitpick the smallest of faults on each car until the winner could be named. You see, this year's lineup of machines was just so good that only one car obviously wasn't CotY material from the get-go. Can you guess which one judging from the list below?
- Aston Martin V12 Vantage S
- Audi R8 V10 Plus

Don't buy that crossover! Buy a cladded wagon instead!

If you're looking to buy a car soon, and you're like most Americans, there's a strong chance you're considering buying a crossover SUV. That's what people want nowadays. People like the tough, tall exterior that suggests adventure and preparedness, they like the high seating position, they like the all wheel drive many have and they like the practicality. Because of this, crossovers have rapidly supplanted typical cars such as sedans, wagons, and more as the most popular vehicles in the country. But they're compromised, too. They're often heavy, thirsty, and expensive compared with more conventional cars. The good news is, there's an alternative, a happy medium between the straight crossover and the traditional car. They're lifted wagons, and they're the best crossover SUVs around. And for those who may not know what we're talking about, we're talking about cars and wagons that have been given a suspension lift for more ground clearance and a higher ride height, and often have all wheel drive standard or optional. They also usually have chunky plastic body cladding to make them look tough and durable. Examples include the Subaru Crosstrek, Audi A4 Allroad, Buick Regal TourX, and Volkswagen Golf Alltrack, among others. Because of the suspension and body modifications, these vehicles fit the trendy crossover mold quite well. And in the case of long-running nameplates such as the Subaru Outback and Volvo Cross Country models, they even have some heritage as outdoorsy machines. They also provide the higher driving position that crossover buyers love. And in some cases, such as with the Golf Alltrack, we've learned they offer better ride quality than their road-oriented siblings. View 9 Photos So these tall wagons offer the key things crossover buyers want, but what makes them better than traditional crossovers is that they have the advantages of the cars they're based on. For instance, the aforementioned Golf Alltrack still drives mostly like a Golf, which is to say, it's nimble, feels peppy, and is easy to maneuver because of its relatively small size. We can't really say the same for the Tiguan, which feels generally more sluggish and uninteresting than the Alltrack. And we mention Volkswagen's compact crossover because it starts at nearly the same price as the Alltrack. Some of the difference in giddy-up can be explained by weight. Normal crossovers can be fairly portly, while these lifted wagons are notably lighter.
