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 >

2015 Ram 1500 EcoDiesel HFE

The Environmental Protection Agency calls the emissions control devices found on diesel Jeep and Ram vehicles a “clear and serious violation of the Clean Air Act” — something the CEO of Fiat Chrysler Automobiles isn’t very happy about.

In their morning announcement, EPA officials claimed the automaker hasn’t done anything to prove the devices found on 2014-2016 EcoDiesel models aren’t regulator-tricking “defeat devices.” According to Brent Snavely of the Detroit Free Press, Sergio Marchionne is mighty steamed, calling the insinuation of cheating “unadulterated hogwash.”

So, what are these eight auxiliary devices, and what penalty could the automaker face if found in violation of the law? Read More >

2018 ford f-150

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. Read More >

Infiniti has had enough of the QX50’s voluptuous curves.

An edgier future awaits the brand’s midsize crossover, as shown by photos of the QX50 “Concept” released ahead of the North American International Auto Show. If this concept looks almost production-ready, that’s because it is.

Borrowing heavily from the earlier QX Sport Inspiration concept, the QX50 Concept’s updated design language isn’t the only way Infiniti plans to lure prospective buyers. Underneath the newly creased sheetmetal beats a very different kind of heart — one two decades in the making. Read More >

It appears the Chevrolet Corvette is in line to receive a new dual-overhead cam V8.

An internal GM document detailing 2018 model year VIN codes was posted to the GM Inside News forum, and down on page five is buried treasure: “Passenger Car Engines for GMNA.”

The very last entry is a unicorn — the long rumored LT5 small block. General Motors lists the engine as “GAS 8 CYL, 6.2L, SIDI, DOHC, VVT, ALUM, GM” under code “Y”, which denotes the Corvette family. Read More >

2016 Ford Mustang GT

Prepare to kiss a famous displacement goodbye.

Ford’s 5.0-liter “Coyote” V8 has dutifully powered variants of the automaker’s Mustang and F-150 since 2011, instilling the brand’s pony car with the kind of heritage that can only be squeezed from 302 cubic inches.

Well, time (and technology) marches on, and Ford’s lower-shelf V8 is due for a replacement. According to a recent report, the Blue Oval folks aren’t choosing sides when it comes to the best way to squirt gas into the new mill. Read More >

2015 Volkswagen Golf TDI

Volkswagen and Audi have begun buying back the thousands of 2.0-liter diesel cars sold involved in its emissions cheating scandal. The deal requires the company to offer buybacks to the 475,000 affected owners. However, the settlement does not carefully outline what condition those returned vehicles have to be in.

Some owners are taking that inch for the full mile and stripping their VWs down before returning them to the company to get their big fat check.
