BMW isn’t known for revolutionary design changes, so it likely won’t be hard to pick the upcoming 3 Series and X3 crossover out of a crowd of domestic and Japanese competitors. Nor will the models’ powerplants see a complete overhaul.

One somewhat surprising claim, given recent events, is that both next-generation models will retain a diesel option in the United States — and a new one, at that. Read More >

Volkswagen Group is about to drop gas and diesel engines like names at a swank party.

The automaker’s CEO has announced a multi-billion push to prepare the company for a much more stringent marketplace, part of which includes giving its internal combustion engine lineup a haircut.

Speaking at an auto industry conference in Vienna, Matthias Müller said the company needs to boost the efficiency of its engines by 10 to 15 percent to stay ahead of picky European and American regulators, Reuters reports. Reaching that goal carries a price tag of $11 billion, spread out over the next five years.

Up to 40 percent of the company’s engines won’t survive the operation, Müller claims. Read More >

General Motors will happily let you configure a newly downsized 2018 Chevrolet Equinox, but moving up a step in power means cooling your heels for a few more months.

The third-generation crossover bowed this spring with a turbocharged 1.5-liter four-cylinder as its base powerplant, mated to a six-speed automatic transmission and front- or all-wheel-drive traction. While that mill generates 170 horsepower and 203 lb-ft of torque, more power is on the way. Read More >

Just in time for spring and dry pavement, FCA heeds the internet credo to Hellcat All the Things by dropping that model’s supercharged 6.2-liter mill in its Jeep Grand Cherokee.

This completes the trifecta of gonzo SUVs, with the Tesla Model X and fish-faced Bentley Bentayga already scorching the pavement. Think a Jeep won’t play in the same league as those rarified SUVs? Both of those vehicles lay claim to 0-60 times in the three-and-a-half second range; with 707 hp on tap, all-wheel drive, and an estimated weight of around 900 lbs more than a Charger Hellcat, the Grand Cherokee Trackhawk should do the same.

2018 Audi TT RS

Math was never this writer’s strong suit, but it’s easy to work out what the looming Audi TT RS means for its occupants: 100 horsepower per passenger. (Does anyone ever venture to that abbreviated backseat?)

That’s right, Audi’s smallest offering will gain an impressive amount of brawn when the new-for-2018 RS variant bows at the New York International Auto Show. It also grows an extra cylinder. Read More >

If you’ve felt left out of the Volkswagen diesel affair until now, chin up. You’ll soon be able to purchase your very own piece of automotive scandal history.

The Environmental Protection Agency has approved the sale of 2015 Volkswagen Group vehicles equipped with Generation 3 2.0-liter diesel engines, making this the first time any of the half-million-plus sidelined vehicles have been legally available to customers since the scandal began.

The contrarian’s list of unlikely daily drivers just grew a bit longer. Read More >

In a developing story, the Stuttgart prosecutors’ office has launched an investigation into employees of Daimler, parent company and manufacturer of Mercedes-Benz BlueTEC engines. At issue is the (lately) very common Germanic malady of diesel infidelity.

There’s no end to the layers of intrigue swirling around the upper echelons of Audi.

Last week saw four engineers who worked on the company’s emissions-rigged diesel engines fired, with one of them, former engine development chief Ulrich Weiss, claiming in court that CEO Rupert Stadler was privy to the deception.

Audi fired back with a lawsuit threat against one or more individuals for “baseless accusations” and the revealing of internal documents. Now, the German publication Bild has released information on a potentially damning document that was reportedly locked away in Weiss’s safe since 2015 for exactly this purpose.

Weiss pulled out the document in a German labor court Tuesday to prove he’s the “pawn” his lawyer claims. Read More >

xvi-v16

The Bugatti Veyron Grand Sport Vitesse produces 1,200 horsepower from its tightly packed quad-turbocharged W16 engine. It is a modern marvel that takes four camshafts and 64 valves to move all the air needed to make this power, and it sure doesn’t come cheap.

An oil change for the Veyron costs slightly more than a new Fiesta ST and requires an engine disassembly due to the extremely tight tolerances. We aren’t likely to find a W16 for sale anytime soon and, even if one does pop up, it won’t go for less than six figures. Not to worry, as a company out of Michigan may have a much better solution — one that makes just as much power with half as many valves and no forced induction. Read More >

Jaguar XE

Another relic of Jaguar’s ill-fated relationship with Ford has been kicked to the curb.

For 2018, Jaguar ditches its old 2.0-liter turbo and adds a new base four-cylinder engine to its lineup, bringing more power and efficiency to the XE sedan and a new starting point for its XF and F-Pace. Read More >

Dodge Challenger SRT Demon

Man, they really make you suffer for it.

In this instance, “they” refers to the Fiat Chrysler Automobiles team that inserted a line from Metallica in the ongoing peep show that is the Dodge Challenger SRT Demon’s teaser campaign. Sigh…

Besides a quote from the most cheesily overused song in the automotive playlist, there’s a technical tidbit to be found in the latest release that sheds a whole lot of light on how the Demon will top its Hellcat sibling in terms of power output.

This antisocial, one-seater Challenger variant sucks a whole lot of air. Read More >

Contrary to the popular mantra, there is a replacement for displacement. The problem is tiny engines that harness technology to boost power output aren’t the greenest things on the road. In fact, the emissions created by small two, three and four-cylinder engines are often out of all proportion to the mills’ Lilliputian displacement.

Volkswagen, realizing it’s staring down the barrel of regulatory non-compliance, has vowed to stop searching for the latest gas- and diesel-powered micro-wonder. Small is out. Normal-sized is in. Read More >

2017 Ram 1500 Laramie Limited Crew Cab 4x4

Spy shots are circulating that show a current-generation Ram 1500 pickup with something missing under the hood.

The picture on the side of the milk carton contains at least two cylinders, as this unusual Ram variant has dispensed with Fiat Chrysler Automobiles’ familiar V6 and V8 engines. Yup, this Ram packs an inline-four. Read More >

2018 Ford Mustang

After luring journalists away from last week’s Detroit auto show for a sneak peak, Ford is ready to show the world its new 2018 Mustang.

That face. Online backlash was moderate to severe when leaked b-roll footage of the new ‘Stang appeared online last night, with some wags claiming the updated model must be unhappy. Beneath the downturned face, however, there’s a host of upgrades designed to satisfy performance-minded enthusiasts.

On that front, ‘Stang purists can breathe a sigh of relief. The 5.0-liter Coyote V8, rumored to be replaced by a 4.8-liter unit, won’t disappear after all. But one long-running engine choice had to skip this party to attend its own funeral. Read More >

mazda skyactiv

While it wasn’t the only car company to make use of a rotary engine, it was certainly the only one to be competitive with them when pistons and pushrods would easily have sufficed. However, those days are gone. Mazda’s SkyActiv technology is well suited for squeezing out an engine’s true potential, but it doesn’t feel particularly quirky or unique.

That could change with the company’s second generation of SkyActiv engines. Mazda is one of only two automakers planning to introduce a motor with homogenous charge compression ignition (HCCI) sometime next year. If you’re unfamiliar, that’s a direct-injection gasoline-powered motor that uses compression, not spark, to ignite fuel — something typically reserved for diesel powerplants. Read More >
