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.

Mixed sales results, but automaker stocks rise on need for cars in Houston

DETROIT — The Big Three Detroit automakers on Friday reported better-than-expected August sales and issued optimistic outlooks for demand as residents of the Houston area replace flood-damaged cars and trucks after Hurricane Harvey, sending their stocks higher. General Motors, Ford and Fiat Chrysler posted mixed August U.S. sales, with GM up 7.5 percent and Ford and Fiat Chrysler down. Japanese automaker Toyota improved sales by nearly 7 percent, while Honda fell 2.4 percent. Still, analysts focused on the potential for Detroit automakers to cut inventories and stabilize used vehicle prices as residents of Houston, the fourth largest city in the United States, are forced to replace tens of thousands, perhaps hundreds of thousands, of vehicles after the devastation from Hurricane Harvey. Mark LaNeve, Ford's U.S. sales chief, told analysts on Friday that following Hurricane Katrina in 2005 "we saw a very dramatic snapback" in demand. That said, Ford sales fell 2.1 percent in August. It sold 209,897 vehicles in the United States, compared with 214,482 a year earlier. Sales were down 1.9 percent in the Ford division and off 5.8 percent at Lincoln. Demand was down for cars, crossovers and SUVs. It was not clear how many vehicles in the Houston area will be scrapped, LaNeve said, saying he had seen estimates ranging from 200,000 to 400,000 to 1 million. Ford's Houston dealers may have lost fewer than 5,000 vehicles in inventory, he said. Ford is the No. 1 automaker in the Houston market, with 18 percent share, according to IHS Markit. The company plans to ship used vehicles to Houston dealers and has "every indication we would have to add some production" of new vehicles to meet demand, LaNeve said. Investor concerns about inventories of unsold vehicles and falling used car prices have weighed on Detroit automakers' shares most of this year. Now, automakers can anticipate a jolt of demand from a big market that is a stronghold for Detroit brand trucks and SUVs. "It's got to be a positive for the industry," LaNeve said. Investors appeared to agree. GM shares rose as much as 3.3 percent to their highest since early March. Ford increased 2.8 percent at $11.34, and Fiat Chrysler's U.S.-traded shares were up 5.2 percent $15.91, hitting their highest in more than five years. GM reported a 7.5 percent increase in U.S. auto sales in August, helped by robust sales of crossovers across its four brands.

Comparison test: 2019 Acura RDX vs. compact luxury SUV competitors

Truth be told, if we were to compare the all-new 2019 Acura RDX with those compact luxury crossover SUVs it would most likely be cross-shopped against, you'd be looking at a different list. Even Acura admits that Lexus and Infiniti are the most likely bogies, but with the 2019 RDX, Honda's luxury brand is attempting to attract those customers who think as much with their hearts as with their heads. And for the most part, those folks have been buying from German brands: the Audi Q5, BMW X3 and Mercedes-Benz GLC-Class. So, to show how the new RDX compares to them, Acura actually provided examples of each during the recent press drive along with a Volvo XC60. All were determined to have greater emotional appeal than the last RDX, and we would certainly agree. For, as much as the previous-generation RDX made sense on paper, it was really hard to get excited about it. And when you're paying extra for a luxury vehicle, shouldn't you get a little excited? Well, as luck would have it, Consumer Editor Jeremy Korzeniewski and I were on hand in Whistler, British Columbia, for the press launch. We didn't have an abundance of time in each RDX competitor, but in conjunction with our usual comparison chart, our impressions should provide a good first taste of how the new RDX compares. Performance and fuel economy Contributing Editor James Riswick: On paper at least, the RDX is gutsier than its comparably powered European rivals. It also weighs the same or less, which logically should mean it'll be the quickest in a straight line. During my brief drives, though, I'm not sure it really stood taller than the three Germans. It at least matches them for smoothness, which is something that can't be said about the Volvo. Fuel economy is lower than them all when you consider all but the Mercedes come standard with all-wheel drive. It's also worth noting that all the competitors are available with engine upgrades, and unless Acura's forthcoming resurrection of Type S models includes the RDX, it should stay that way. Consumer Editor Jeremy Korzeniewski: Line 'em all up in a drag race, and I have a feeling the Acura would squirt away to victory. A good bit of that, though, would be due to its 10-speed automatic transmission, which offers a huge spread of ratios and fires off extremely quick shifts. In the real world, I'd guess fuel economy will be similar across the board, so I'm willing to call that category a draw.
