Jay Leno brings a rotary-powered VW Beetle to the garage

It takes something really unique or inventive to pique Jay Leno's interest. His show, Jay Leno's Garage, has featured everything from concours-worthy classics to completely custom, home-built machinery. How do you get Leno to feature one of more than 20 million Beetles on his program? Stick a turbocharged rotary engine under the hood. The Beetle's owner, Mario Markakis, swapped the car's stock flat four-cylinder for the Wankel engine from a 1990 Mazda RX-7 Series 5 Turbo. The engine's 250 horsepower are fed through a reinforced version of the Beetle's stock four-speed transmission. That's about five times the original engine's output. It works well, with the car putting down some impressive times at the drag strip. Markakis did most of the work to the Beetle in his garage. In addition to the engine swap, he's modified the car's brakes, suspension, and interior. Check out the video to hear all the details of this custom Wankel-powered Volkswagen.

Meet ZelectricBug, the amazing '63 VW Bug converted to EV power

No word a lie, we here at AutoblogGreen are fans of classic cars. What we are not fond of, however, is the pollution that their inefficient engines create, and so it's great to see our old favorites lovingly up-cycled with electric drivetrains. The ZelectricBug is a beautiful example of how new, cleaner life can be breathed into an old Volkswagen Beetle. Now, we first came across this particular automobile during the Refuel event last summer and we were struck by its cleanly done conversion then. Aside from a few snaps in our gallery, though, we didn't give it the kind of attention it deserves. Fortunately, the good folks over at Roads and Rides have rectified this by turning their pro video camera skills onto the 1963 V-Dub and producing a nice little segment to accompany their write up. Scroll below to see the finished footage and head over to their website for some stills. If all this gives you a hankering for your own Zelectric, the company does have plans to sell to the public starting this summer. If you don't want to wait, EV West, the guys who did the drivetrain work on this car, have conversion kits available for Beetles, as well as a number of other vehicles.

Cruze Diesel Road Trip reveals the good and bad, but no ugly

Most of us have strong opinions on diesel-powered cars based on our perceptions of and experience with them. I used to thoroughly dislike oil burners for their noise, smoke and lackluster performance, and the fact that they ran on greasy, smelly stuff that was more expensive than gasoline, could be hard to find and was nasty to get on your hands when refueling. Those negatives, for me, trumped diesel's major positives of big torque for strong acceleration and better fuel economy. Are any of those knocks on diesel still valid today? I'm not talking semis, which continue to annoy me when their operators for some reason almost never shut them down. At any busy truck stop, the air seems always filled with the sound – and sometimes smell – of dozens of big-rig diesels idling endlessly and mindlessly. Or diesel heavy-duty pickups. Those muscular workhorses are far more refined than they once were and burn much less fuel than their gasoline counterparts. But good luck arriving home late at night, or departing early morning, without waking your housemates and neighbors with their clattery racket. No, I'm talking diesel-powered passenger cars, which account for more than half the market in Europe (diesel fuel is cheaper there) yet still barely bump the sales charts in North America. Diesel fuel remains more expensive here, too few stations carry it, and too many Americans remember when diesel cars were noisy, smelly slugs. Also, US emissions requirements make them substantially more expensive to certify, and therefore to buy. But put aside (if you can) higher vehicle purchase and fuel prices, and today's diesel cars can be delightful to drive while delivering much better fuel efficiency than gas-powered versions. So far in the US, all except Chevrolet's compact Cruze Diesel come from German brands, and all are amazingly quiet, visually clean (no smoke) and can be torquey-fun to drive. When a GM Powertrain engineering team set out to modify a tried-and-true GM of Europe turbodiesel four for North American Chevy Cruze compacts, says assistant chief engineer Mike Siegrist, it had a clear target in mind: the Volkswagen Jetta TDI 2.0-liter diesel. And they'll tell you that they beat it in nearly every way. "I believe we have a superior product," he says. "It's powerful, efficient and clean, and it will change perceptions of what a diesel car can be." The 2.0L Cruze turbodiesel pumps out 151 SAE certified horses and 264 pound-feet of torque (at just 2,000 rpm) vs.
