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.

The 2018 Audi SQ5 looks mean and switches to turbo power

Audi's huge Q8 wasn't the only crossover introduced by the German automaker at this year's Detroit Auto Show. Right alongside it came the 2018 SQ5, the brand's high-performance midsize crossover. This newest version ditches the previous generation's supercharger in favor of a turbo for its 3.0-liter V6. The powertrain is similar to the one used in the latest S4 and S5. Horsepower remains unchanged compared to the last SQ5 at 354, but torque sees a healthy increase to 369 pound-feet, and it's available anywhere from 1,370 to 4,500 rpm. The car itself weighs about 77 pounds less, too. It's a combination that should make the SQ5 pretty entertaining off the line. Coupled to the turbo engine is an eight-speed automatic and standard all-wheel drive. Power delivery and handling can be enhanced with a Quattro sport rear differential that can shuffle power left and right to aid cornering. Audi says the torque vectoring system can send almost all rearward power to one wheel as necessary. The differential is available as part of the S sport package, which comes with other upgrades including air suspension. The suspension gives the crossover a lower ride height by default. Both height and firmness can be adjusted, and it offers an "offroad" position that raises the car for maximum ground clearance. Inside, the SQ5 comes with a sportier interior than its Q5 counterpart. It comes with prerequisites such as a flat-bottomed steering wheel and more-bolstered seats. Audi also provides a Bang & Olufsen sound system and standard Apple CarPlay and Android Auto. The cabin experience can be further augmented with Audi's Virtual Cockpit LCD instrument panel, as well as driving assists such as a variable-ratio steering rack and adaptive cruise control that can handle stop-and-go traffic from 0 to 40 mph. Audi will begin selling the new 2018 SQ5 here in spring of 2017. Pricing for it and the Q5 has not yet been released. Related Video:

Volkswagen finds CO2 'irregularities' for 800k vehicles

The latest issue for Volkswagen affects another 800,000 vehicles, and this time its for irregularities in CO2 emissions certifications. VW estimates this issue could cost the company $2.2 billion to fix. The company officially makes no specific mention of which engines are covered, the models they are in, or even where they are located. VW discovered the situation during its ongoing internal investigation, and, according to the automaker, "it was established that the CO2 levels and thus the fuel consumption figures for some models were set too low during the CO2 certification process." Most of the affected vehicles are diesels, and the company is now reaching out to "the responsible type approval agencies" to figure out the next step. While VW isn't officially confirming which models and engines are involved, Automotive News reports that it affects some 2012 and later VW, Audi, Seat, and Skoda models with the company's 1.4-, 1.6-, and 2.0-liter diesel engines, as well as the 1.4-liter ACT gasoline engine. The issue mainly affects vehicles sold in Europe. "The Board of Management of Volkswagen AG deeply regrets this situation and wishes to underscore its determination to systematically continue along the present path of clarification and transparency," CEO Matthias Muller said in the announcement. Volkswagen Group of America spokesperson Jeannine Ginivan was able to provide some further clarification to Autoblog. "This is not related to US-certified vehicles," she said. Clarification moving forward: internal investigations at Volkswagen identify irregularities in CO2 levels Matthias Muller: "Relentless and comprehensive clarification is our only alternative." Around 800,000 Group vehicles could be affected Initial estimate puts economic risks at approximately 2 billion euros The Volkswagen Group is moving forward with the clarification of the diesel issue: during the course of internal investigations irregularities were found when determining type approval CO2 levels. Based on present knowledge around 800,000 vehicles from the Volkswagen Group could be affected. An initial estimate puts the economic risks at approximately two billion euros. The Board of Management of Volkswagen AG will immediately start a dialog with the responsible type approval agencies regarding the consequences of these findings. This should lead to a reliable assessment of the legal, and the subsequent economic consequences of this not yet fully explained issue.
