Adam Carolla is world's the least helpful test drive co-pilot

If you were going to test drive a new car, who would you want to take with you? Your spouse? A friend? Maybe an automotive journalist? Well take it from us: there's one of us riding shotgun just about every time we go to drive anything, and we're not all we're cracked up to be.
How about a celebrity comedian? Well, that largely depends on which comedian we're talking about here. Some - say, Jerry Seinfeld or Jay Leno, for example - might be more helpful than others, being more or less schooled in the finer points of the modern automobile. Adam Carolla might seem like he belongs on that list too, but in this latest video for a friends at Edmunds.com, the one-time host of The Car Show on Speed TV seems bent on being as comedically intrusive as possible. Which may be funny, but helpful? Not so much. See what we mean in the video below, and the next time you go to test drive a new car, you just might find the world's most popular podcast host climbing in with you.

Electric turbos promise big performance and efficiency gains in the near future

An electric turbo system boosts efficiency between 15 and 20 percent, according to Audi.
Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.

Audi RS3 spy shots foreshadow an ultra-hot hatch

Not all vehicle prototypes and mules require heavy camouflage - sometimes they can be hidden in plain sight. That's probably what Audi was hoping for while testing its new RS3 wearing S3 duds, but thanks to some visual and audible telltales, our spy photographers were able to recognize this as a precursor to the marque's ultra-hot hatch testing near the Nürburgring.
Our photographer noticed the signature exhaust note of a five-cylinder engine, which suggests the RS3 could borrow its motivation from the excellent TT RS. Producing at least 340 horsepower, this 2.5-liter turbo powerplant could be the perfect answer for the new A45 AMG from Mercedes-Benz. The big brakes on this RS3 mule give us our best idea about the car's high-performance intentions, with Audi RS wave brake rotors and six-piston calipers peering out from behind the oversized wheels.
In production form, the RS3 should have a much different appearance from what you see here, with sportier design cues including oval-shaped dual exhaust outlets and a more aggressive front fascia. While we're still waiting for our first taste of the S3 in the North America, we'll be holding our breath for the RS3 to make its way here, as well.
