This Kia can calculate your body fat

At the 2014 CES, Kia binged on three-letter acronyms with a slew of connectivity technology that culminated in the first U.S. debut of its KND-7 concept. For a company whose name is composed of three letters, it's not entirely unexpected.

Future Audis may time traffic lights for you

Here's a trick efficiency-chasing hypermilers have been using for years: spotting the cycles of stoplights from 100 to 200 yards out and letting the car coast up to the light just before it turns green, then carrying on without ever letting the car come to a complete stop. These hypermilers, along with professional truck drivers, do this because they know that accelerating from a standstill burns the greatest amount of fuel, and because letting a car coast up to the light with the automatic transmission downshifting by itself is easier on the transmission than stomping on the brakes right beneath the stoplight. Oh, and it's easier on the brake pads as well.

Tesla Model S outsells luxury competition

As if Tesla needed any more good news this month, first-quarter sales are in and the electric Model S outsold the Mercedes S-class, Audi A8 and BMW 7-series, according to “CNN Money.” In the first three months of 2013, Tesla sold 4,750 sedans while Mercedes sold 3,077 of the S-class, BMW sold 2,338 of the 7-series and Audi sent 1,462 A8s out of the dealership. The Model S does have its sticker price going for it. The base model can be had for $69,900 -- possibly less with tax incentives -- while the cheapest S-class goes for $93,255, the 7-series for $74,525 and the A8 for $73,095.
