Video: Michael Mauer on the 991-series Porsche 911

Porsche has released a video featuring its Design Director, Michael Mauer, explaining how he and his team went about redesigning the 911, an ‘automotive, engineering icon' as he describes it. "What we as designers are striving to above all is to optimize the width to height ratio with the result that although the 911's width has not increased, the front axle area has become wider, and we've managed to make the roof a bit lower," Mauer explains via a rather dramatic-sounding voiceover.

A look at Toyota future products

Toyota has slipped behind competitors in drivetrain technology and now must play catch-up against the likes of Ford, Hyundai and Mazda. Much of Toyota's lag stems from engineering resources being diverted by the unintended acceleration crisis and other quality miscues in the past two years. Now expect Toyota to focus more on turbocharging and direct injection, and it may even bring a couple of diesels to the United States as part of midcycle changes.

Lexus LFA, from design to dealership in six minutes: Video

Seeing the Lexus LFA in person makes it easy to forget that the supercar has been in development for more than 10 years. But you do get a wondrous amount of technology for $375,000, the carbon-fiber body, a retractable rear wing and a compact V10 so fast that analog gauges couldn’t keep up with it. Add to that 553 hp, 354 lb-ft of torque and a 202-mph top speed, and we just had to put the LFA to the test at our favorite local racetrack.
