Audi unveils A3 Sportback G-Tron with bi-fuel power, 808-mile range

By this time next year, the Audi A3 Sportback will be offered with a variety fuel-efficient powertrains ranging from diesel to the all-electric E-Tron, but perhaps the most interesting is the all-new G-Tron model, which uses Audi's innovative carbon-natural compressed natural gas called e-gas. Previously called A3 TCNG, we first heard about this technology last year, but now Audi has confirmed that this low-emission, sustainable-fuel will debut by the end of this year on the A3 Sportback G-Tron.
To create this e-gas, a plant in Werlte, Germany uses electricity to split water into hydrogen and oxygen. As hydrogen fuel cell vehicles become more popular, Audi says that this process could also be used to produce hydrogen fuel, but to create CNG, it mixes the hydrogen with carbon dioxide to create "synthetic methane." Since it is identical to the CNG available today, Audi's e-gas can be shipped and stored using the existing CNG infrastructure. Making the whole process even greener, Audi obtains the CO2 for this process from a nearby biogas plant, which would otherwise be released into the atmosphere.
Differentiated from the regular versions of the A3, the G-Tron features a pair of tanks under the rear cargo floor holding 15.43 pounds of CNG, which can power the car for almost 250 miles. What's more, the A3's conventional gasoline tank is still in place, giving the car an addition 560 miles of range. In total, that means the A3 G-Tron has a driving range of more than 800 miles. To run on both CNG and gas, Audi made changes to the car's 1.4-liter four-cylinder engine (including the turbo, cylinder head and fuel injection system) and catalytic converter.

BMW can't build enough M3 wagons, but the U.S. won't see any

Why, oh why, won’t the automobile companies that supposedly cater to Americans give us a viable touring wagon? Seems that BMW is one manufacturer thatÂ’s aware of the question, but skirts the answer. WhatÂ’s more frustrating is that the German company, and others, have for years been off-handedly tossing out the same refrain: “Maybe weÂ’ll bring a wagon back to the U.S.” Not. All the more irritating then is the news that the Bavarians have increased production in Munich of its M3 Touring longroof version to keep up with demand. The information comes via Bimmer Today, which spoke with BMW M CEO Frank van Meel. He said that the company was surprised by the amount of interest in the M3 Touring since its debut during last year's Goodwood Festival of Speed. In fact, he said, the company had to facilitate a production ramp-up within its Munich facility. Despite that increased production, the backlog of orders means that customers are still on wait lists, he said. Last year, van Peel admitted that demand for M-wagons in the U.S. has been steadily increasing, and exporting a touring example was a concept BMW was "taking into consideration.” Crossovers certainly are this decadeÂ’s version of the wagon, which leaves American enthusiasts will few choices: only expensive versions from Audi, Volvo and Mercedes-Benz and a couple of others. Details that were announced last year — a few months before the wagon went into production for sale in Europe, the U.K. and elsewhere — noted that the M3 Touring was only available in Competition spec with xDrive all-wheel drive and a 3.0-liter twin-turbo inline-six with 503 horsepower and 479 pound-feet of torque. Pricing started at GBP80,550 ($105,000 U.S.) More data on the M3Â’s intro here. Related video:

Sunday Drive: From a mid-engine 'Vette to a restomod RV

Automotive enthusiasts are a diverse bunch. As proof, we present last week's top posts on Autoblog, starting with some really good spy photos of the upcoming mid-engine Chevrolet Corvette. Will it be sold alongside a classic front-engine 'Vette? We have no idea, but we can't wait to find out. Up next is a pickup truck. Can't get much further from a supercar, right? At least both the Corvette and the 2019 Ram 1500 – which will debut a radical new design that appears to eschew the mini big-rig look of past Rams in favor of something more refined – are both American. Decidedly not American? The Mercedes-Benz G-Class SUV. The boxy off-road 'ute looks a heck of a lot like the old one, which is probably a good thing, but we know it'll be fancier and more luxurious than ever before. Check out the leaked images below. Also hailing from Germany, but sharing absolutely nothing else in common at all, is the Audi A4 Allroad. We've been driving this all-wheel-drive wagon for a while now, and we like it quite a bit. And, last but not least, is a 1959 bus that's been converted into an RV. Like we said, y'all certainly are a diverse bunch.
