Fuel-economy ratings for cars sold in Europe have long been wildly unrealistic, sometimes more than 30 percent more optimistic than real-world consumption figures. Today, that will change. As of September 1, two new and more stringent testing regimes are to be used for certifying new vehicles going...

Diesel-powered cars, long a staple on European roads, are starting to lose favor as million of dollars of inventory begins to pile up in used diesel models.

The United Kingdom will follow in the footsteps of some European countries as it announced plans to ban the sale of gasoline- and diesel-powered cars by the year 2040. The initiative closely follows a similar announcement from France, which also declared 2040 as the year it will phase out...

The fallout from the Volkswagen diesel scandal has cost the fuel plenty of not-so-great headlines, but the idea that diesel will soon die off entirely for passenger vehicles simply isn't true. A report in The Car Connection compiled the proof to show diesel is far from its deathbed. There remain...

Volkswagen has underscored that its diesel cars affected by its TDI emissions scandal are safe to drive. It highlights that on a special consumer site dedicated to information about these models, which include the 2009-2015 Jetta TDI, 2009-2014 Jetta SportWagen TDI, 2010-2015 Golf TDI, 2015 Golf...

Time was, the Toyota Prius hybrid was the unquestioned technology champion and king of the fuel-efficiency battles. No longer, though.

Jeep will use the Geneva Motor Show in March to launch the latest addition to its Cherokee range--the Cherokee Diesel. Hurrah! The bad news is that there are no intentions to bring this model to the U.S, where the most efficient Cherokee currently utilizes a 2.4-liter, four-cylinder gasoline...

Look out, owners of 200-mph testosterone-supplement poster cars. If there ever was a real hypercar, it's the Volkswagen XL1. Although in recent years the term hypercar has been distorted—to include cars that are faster (and often even thirstier) than those supercars from Lamborghini, Ferrari...

Audi has continued its dominant run at the world's most famous endurance race, winning the Le Mans 24 Hours on Sunday. The team's twelfth Le Mans victory is also the second for its hybrid race car, the R18 e-tron quattro. France's Loic Duval, Scotland's Allan McNish and Dane Tom Kristensen took the...

We're often asked why more automakers don't sell diesel-electric hybrid vehicles. There are plenty of good reasons why, but that doesn't stop people wanting the twin-pronged benefits of highway and city economy. SUV buyers could get their wish if Land Rover brings diesel-electric hybrids to the...

While the assembled hoardes drooled over Ferraris, Porsches and McLarens at March's Geneva Motor Show, those of a greener disposition were more interested in another vehicle. Launched alongside the hybrid hypercars was a true hybrid supercar in its own right--the plug-in diesel hybrid Volkswagen...

There is, at the moment, only one production diesel plug-in hybrid car on sale, and it's currently only sold in Europe. That car is the Volvo V60 Plug-In Hybrid, combining the long-distance touring ability and economy of a diesel powertrain with the short-distance cleanliness and inexpense of...

We’ve already told you the BMW 3-Series would be getting a new four-cylinder diesel engine in the U.S., and that the engine, a 2.0-liter four-cylinder turbodiesel, would appear in a new 328d sedan later this year. Now we can finally reveal the car, as it has made its debut this week at the...

The Volkswagen Audi Group is a master at filling niches, and another one is heading our way from early 2014. For the customer who wants the VW Jetta's sedan bodystyle and 2.0-liter diesel engine--but prefers the Audi A3's more upmarket image--Audi presents the 2015 A3 TDI Sedan. Unveiled at the...

The New York Auto Show is almost upon us, and rather than the usual raft of green concept cars, it's the production vehicles we're most looking forward to this year. Several green models are set for unveiling, with everything from budget subcompacts, through diesel sedans, to more economical trucks...

Consider this: The average semi truck is actually quite economical. No, really. A typical long-haul truck averages between 5.5 and 6.5 mpg. But it's also really, really heavy--up to 80,000 pounds, for a fully-loaded trailer. That's around 36 tons, which puts some perspective on how hard each of...

Diesel cars are at their most economical on long, steady journeys, and plug-in hybrids are at their best for shorter trips. So why haven't the two been combined yet? Actually, they have--and you're looking at the very first one. The Volvo V60 Plug-In Hybrid is the first diesel plug-in hybrid...
