It looks like Land Rover has finally waked up from its slumber and started to care about fuel economy. Its new Freelander 2 TD4_e compact SUV is equipped with engine start-stop technology, getting quite popular these days.

The times have certainly changed for the sport utility market. While SUVs enjoyed tremendous sales success in recent years, the rising price of gasoline coupled with a weakened economy has driven down SUV sales more recently. As a result, dealers are struggling to move SUV inventory these days, even with attractive incentives. The hardest hit by this trend may be domestic automakers as they have relied on the sales successes of gas guzzling midsize and large SUVs.

Employing a number of advanced techniques, Toyota's engineers have managed to make the third-generation Lexus RX450h hybrid SUV even more efficient and powerful.

Official images demonstrate that the upcoming Porsche Panamera four-dour luxury coupe doesn't look that bad. Well, it even looks good, I dare say.

We've all seen the miniature Ferrari engine before, but here are some good details on a guy that has put together a working V8 engine that can sit on a kitchen table. The quality of the work is amazing.

The new Performance Studio special edition model successfully eliminates 2009 ML 63 AMG's one and only weak point: lack of luxury touches in its otherwise gorgeous interior.

Oddly enough, the first image that came to mind when I witnessed the Urban Whip was the Power Wheels Barbie Cadillac Escalade®, which is strange considering I've never seen nor heard of a Power Wheels Barbie Cadillac Escalade®. I just figured if there was one, this is probably what it would look like. For curiosity's sake, I then went to the Toys "R" Us website, and lo-and-behold...

We still love the big guy, even if the smaller GLK has garnered the bulk of our attention the past couple months. But we're not the only ones still fond of the GL. ART Tuning – purveyor of a wide assortment of aftermarket Mercedes modifications – has just announced announced a new tuning program for the SUV, and they're calling it the "GL MAMMUT."

The 2009 Porsche Cayenne Diesel will be motivated by an engine outsourced from the VW Touareg 3.0 TDI. The V6 oil-burner will be retuned to produce extra 15hp and +50Nm of torque, but it still doesn't seem to be adequate for the job. It's the Cayenne it has to power, after all.

Just as usual, the program includes a body kit, an interior enhancement kit, and a comprehensive engine upgrade program.
