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.

Editors' Picks January 2022 | Ford Maverick, Jeep Grand Cherokee and more

This month, we awarded Editors' Pick awards to a number of totally redesigned, new models. Most notable of the bunch is the 2022 Ford Maverick. Ford took a chance on a new segment, and its execution is as close to perfect as we could hope for. The Hyundai Santa Cruz is a worthy competitor, though, and was also named an Editors' Pick. Also in this list, we have the redesigned Jeep Grand Cherokee. It's an excellent SUV, and it's only going to get better when the plug-in hybrid 4xe model hits the roads. In case you missed our previous Editors' Picks posts, here’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in January that earned an EditorsÂ’ Pick. 2022 Jeep Grand Cherokee Quick take: Jeep's midsize SUV hits it out of the park with the latest generation. We could stand to see some powertrain innovation, but the Grand Cherokee's premium proposition is sound. Score: 8.0 What it competes with: Honda Passport, Hyundai Santa Fe, Ford Edge, Chevrolet Blazer, Nissan Murano Pros: Highly capable, luxurious interior, choices aplenty Cons: Pricey, fuel economy From the editors Associate Editor, Byron Hurd — "Jeep did almost everything right with the redesigned Grand Cherokee. Its powertrain offerings are fairly unremarkable, but the new two-row 4xe will go a long way toward addressing that. It's an otherwise fantastic, modern, luxurious Jeep SUV." In-depth analysis: 2022 Jeep Grand Cherokee First Drive Review | 1 fewer row, 1 more touchscreen   2022 Ford Maverick Quick take: The Ford Maverick offers tremendous value, efficiency, incredibly well-thought-out packaging, plenty of storage, a fairly engaging drive and ease of use, all with the utility of a pickup bed. We like the hybrid, but the EcoBoost engine and FX4 package offer more capability. Score: 8 What it competes with: Hyundai Santa Cruz Pros: Very affordable, Hybrid fuel economy, compact size Cons: Tight backseat, FWD only Hybrid, no cruise control in base trim From the editors: Green, Senior Editor John Beltz Snyder — "The Maverick is simply a dynamite package. It's smart, useful, drivable, efficient, providing affordable utility in the underserved compact pickup segment.

Next Audi RS4 to get an electric turbo?

We don't yet know if the next Audi RS4 will come to the US, but whoever gets it could find an electric turbocharger under the hood according to a report in Auto Express. The 4.2-liter V8 that has served for two RS4 generations is retiring from the line, replaced by a twin-turbocharged version of the supercharged 3.0-liter V6 used in the S4. But instead of using two sequential turbochargers - a smaller one to eliminate lag while a larger, more powerful turbo spools up - batteries charged by brake regeneration could power a first-stage electric turbo. The idea hasn't been publicly appointed for a particular model, as Audi's technical chief Ulrich Hackerberg has said that due to expense, that kind of setup "would only be used be used on the very top end models." Since the technology cuts down on the use of exhaust gases, it would also also help in markets like Europe where CO2 emissions are a factor. No matter whether it benefits from all conventional or some electric boost, the horsepower number for the twin-turbo V6 will be more than 420 hp but less than 503 hp, the rating of the V8-powered Mercedes-Benz C63 AMG. Auto Express believes Audi will want to maintain the power gap between the 333-hp S4 and previous, 444-hp RS4. With Hackenberg saying the new S4 will make more than 350 hp, that gets the coming RS4 up to at least 461, but AE figures it "could deliver as much as 480 hp." We'll find out sometime after the S4 launches next year.
