The new Mercedes GLE Coupe

When BMW launched its X6, the world's motoring press wondered if the Bavarian giant had finally gone insane. After all, who would want a coupe combined with an SUV? As it turns out, the X6 was popular enough to warrant a second generation, and the concept has also been applied to create the smaller X4. Mercedes is also keen to get in on the coupe/SUV combo action with its new GLE Coupe.  Read More

Audi has sold over half a million of its A1 hatchbacks since the model's launch in 2010, so when it came to updating the small hatch, the German manufacturer hasn't messed with its winning formula.

Proportionally the car is similarly sized to the Mini

Prof. Rolf Reitz (center) and members of his student team with the RCCI-powered Saturn

Five years ago we first heard about a Caterpillar diesel engine located at the University of Wisconsin-Madison, that had been modified to run on an unlikely-sounding mixture of diesel and gasoline. Not only did the one-cylinder engine work, but it was more efficient than pure-diesel or pure-gas engines at converting the chemical energy of fuel into motion. Sitting in a basement lab, however, isn't the same as experiencing use in the real world. That's why students at UW-Madison, led by Prof. Rolf Reitz, have now put another diesel/gas engine into a 2009 Saturn.  Read More

Now, Mazda has joined the global trend for downsizing engines with its new turbocharged 1.5-liter SKYACTIV diesel. After teasing us at the Geneva Motor Show, the Japanese car company has finally released details of its new motor.  Read More

The all-new T4 is ready for rough rides

In 2012, Brazilian 4x4 manufacturer Troller, which was purchased by Ford Brazil in 2007, provided a sneak preview of what its next T4 utility vehicle would look like with its TR-X concept. It has now folded the look and feel of that concept into the new production T4, a 4x4 that is making other parts of the world beg Ford for a rebadged export.  Read More
