He lost his job for it, but Kim Gwang-ho, a 25-year Hyundai veteran at the automaker’s Seoul, South Korea facility, knew he needed to speak out.

The engineer blew the whistle on his employer, reporting the automaker to both South Korean and American officials after uncovering evidence Hyundai was covering up a defect in several of its models. Kim even published internal documents to back up his claim.

Kim, 55, was fired from his job, but authorities took note. As a result, a further 240,000 vehicles — totaling 12 models — have been added to a recall already 1.4 million strong.

Ralf Speth isn’t having it. Across Europe governments are cracking down on the use of diesel vehicles in a bid to lower air pollution, especially in the Jaguar Land Rover CEO’s own country. London has announced plans to levy stiff charges on anyone driving a diesel-powered vehicle through central areas of the capital starting in early 2019, adding fuel to the anti-diesel fire. Paris, Berlin and Athens also plan to ban the technology.

With compression ignition still a significant part of the automaker’s engine lineup — both in Europe and North America — Speth recently defended the technology’s importance in a finger-pointing spiel. The world needs diesel, he claimed, and the media (and Volkswagen) haven’t done anything to help the situation.

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.

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.

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.

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.

Honda isn’t one to dish details on a new product miles ahead of a debut, but information has a way of springing leaks.

An email sent to Honda aficionados from the automaker has ended up on the CivicX forum, and its description of the upcoming Civic Si’s torque rating is apparently legit. However, those fans wish it wasn’t, as the number isn’t exactly that of a performance monster.

If you’re worried the 2018 Chevrolet Camaro ZL1 1LE unveiled this week will be the hottest round fired from the Chevrolet Camaro magazine, fear not. The famed Z/28 will reportedly live on, and not just in memories.

While the upcoming ZL1 1LE utilizes the scorching LT4 drivetrain of its brother — and adds enough downforce-generating attachments to punch through the asphalt — it doesn’t offer Camaro buyers more of what they really want. That being moar powah, obviously.

More power is, apparently, on the way.

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.

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.

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.

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.

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.

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.

Being on top doesn’t mean a company can take its customer base for granted. Not satisfied with basking in the goodwill generated by the F-150’s best-selling status, Ford Motor Company has unveiled a refreshed 2018 model and a host of new hardware upgrades.

While the upcoming F-150 sports an evolutionary facelift, it’s what’s under the hood that stands to tempt a new range of buyers.
