Got a lot of email from you about turbos and superchargers, the purposes and differences of each. Not surprising, since there are a lot of both showing up in all kinds of cars these days, not just in hot rides. So this week we lay out the difference by walking you through some cutaway engines.

We're pretty smart about the data on our computers and phones these days, but most people do not give enough thought to the fact that … Read more

CNET on Cars 12: BMW 750Li vs. Lexus LS 460

Subscribe:

An embarrassment of riches this time as the 2013 BMW 750Li and Lexus LS 460 hit our garage on the same day. Some assignments are just more comfortable than others! But while both cars are luxurious, one felt much readier to cut it up on the road to my hands, and you might be surprised which.

CNET on Cars: The Cadillac ATS shines

Rumor Has It: Signs point to PlayStation 4 at E3

We're back from CES, and getting right back into the swing of the rumor mill.

This week, rumors of a 4.8-inch iPhone "Math" (say, what?) have been swirling, but we're blaming it on a bad translation.

We bet you can guess what it is (hint: read the headline of this post).

Top car tech from CES and the Detroit auto show: CNET On Cars Episode 10

Subscribe:

We open the year with a double header from what I think are the two biggest car events in the U.S. each year: The Consumer Electronics Show and the North American International Auto Show in Detroit. The latter makes total sense in a show like this, but CES has also moved up the ranks as a major moment for car tech. I mean, Ford and GM climbed all over each other in a battle to be the first major automakers … Read more
