General Motors wants better performance from its boosted engines, so it headed to the patent office with a design for a new two-stage turbocharger — one that eliminates the drawbacks of the existing setup.
According to a document published by GM Inside News, the General filed the patent on May 19. The design (mated to a four-cylinder engine) isolates the low-pressure and high-pressure turbines, calling on one or the other (but not both) at different engine speeds and loads. (Read More…)
Ford’s comparing itself to the Germans again, but this time the vehicle isn’t a Granada, and the disco era isn’t still raging.
The automaker just announced it boosted the output of the 2.7-liter EcoBoost V6 in the 2017 Fusion Sport, keeping horsepower levels the same while adding an extra shovelful of torque. (Read More…)
GMC’s got a secret, but it’s keeping it hidden under the hood of its 2017 Sierra Denali 2500HD for now.
The company released photos today of the their updated heavy-duty pickup, and made sure everyone noticed the functional hood scoop above its massive grille. (Read More…)
If you want to own one of the world’s best engines (as ranked by a panel of multi-national auto journos), you don’t necessarily have to find a higher paying job or buy a plane ticket to Europe.
Most categories at the recently announced 2016 International Engine of the Year Awards were won by high-end powerplants and European mills you won’t find in North America — except for one entry dominated by Ford. (Read More…)
The complaint most often tossed at Formula 1 is that despite being the (alleged) pinnacle of motorsports, its relevancy to road cars has disappeared.
That same feeling is what brought us to the current formula of tiny 1.6-liter turbocharged six-cylinder engines, all coupled to a complex hybrid system. Since that move, the racing series has focused more on engine development that in almost any era before, and with that comes a breakthrough in the way we look at thermal efficiency. (Read More…)
If you missed your chance getting into a limited edition Ford GT supercar last week, your EcoBoost-powered dreams might not be over.
Dave Pericak, director of Global Ford Performance, recently told Autocar that the 600-plus horsepower heart of the GT could beat on — in other low-volume specialty models. (Read More…)

I’ve been an enthusiast and part-time DIYer for years now. I love to learn about everything automotive.
My question for you: why are cars with small engines always inline-fours? Why do manufacturers not put 2.0-liter V6s into cars? I know they don’t usually use big displacement inline-fours because of NVH issues, but what about the other way around?
Thank you for your question, Brian. I’ve been wondering about this very aspect of engineering for a while and you just gave me enough push to go sniffing for answers.
Three hybrid powertrains and three performance powertrains bookended Wards Auto’s top 10 engines, which was released last week.
The list included repeat winners such as the Ram 1500 Ecodiesel 3-liter six, Subaru’s turbo flat-four and Nissan’s veteran VQ 3.5-liter V-6. Appearing for the first time was BMW’s replacement for its N55 turbocharged, 3-liter straight six as well as General Motor’s LGX V-6 — which appears in several Cadillac models and in the new Chevrolet Camaro — with cylinder deactivation.
Volvo’s twin-charged 2-liter four and Ford’s famous flat-plane crank V-8 from the Shelby GT350 made the list for the first time in 2016. Volkswagen’s engines were excluded from consideration this year because of the company’s admission that its diesel engine cheated through emissions tests.
According to Reuters, Volkswagen may have suspended engineers — including top engineers for Audi, Volkswagen and Porsche — without any evidence.
According to the report, more than 10 engineers were suspended in the fallout after it became clear the automaker cheated its way through emissions tests in the U.S. and Europe. It’s not clear if the suspended engineers would be reinstated at the company.
Reuters reported that VW’s internal investigation revealed that the illegal “defeat devices” began appearing in cars around 2008 after engineers discovered that their engine, which was costly to produce, wouldn’t pass emissions tests.
Used car dealerships have filed a proposed class action lawsuit against Volkswagen over cars they say they can’t sell and are seeking the same compensation the German automaker is offering its new car dealers, Reuters reported (via Automotive News).
According to the attorney representing the dealers, selling the cars could put the businesses at risk of lawsuits from their customers. If the used dealers can’t sell their in-stock Volkswagen diesels, the businesses would shoulder the losses, the lawsuit alleges. (Read More…)
