DETROIT – When engineers set out to make the all-new 2013 Cadillac ATS as light as possible they used advanced materials to minimize weight throughout the compact luxury sports sedan but never compromised performance capability.

Lightweight parts such as an aluminum hood and magnesium engine mounts help ATS achieve a curb weight less than 3,400 pounds, and highway fuel economy well over 30 mpg. Keeping weight down also enabled balanced distribution of vehicle weight that helps delivers a world-class driving experience.

“We designed and engineered ATS’s vehicle architecture to deliver quick, nimble and fun-to-drive dynamics,” said David Masch, ATS chief engineer. “We distributed mass to key areas, much like an athlete builds muscle where he needs it most. This enabled ATS to achieve the performance characteristics that luxury sport sedan buyers demand.”

One seemingly heavy way the ATS engineering team achieved its performance goals was using cast iron in the rear differential instead of aluminum, a learning taken from the performance-tuned CTS-V.

The differential provides torque and rotation to the wheels, and ATS’s cast iron design helped distribute weight equally between the front and rear wheels to provide agile handling while reducing noise and vibration. Cadillac benchmarked it against world-class competition to deliver a driving experience that is as well-tuned for sound as for ride and handling.

Unlike a differential made from aluminum, which expands and contracts twice as much in response to temperature change, a cast iron differential is stronger and retains its shape better under temperature extremes, which allows the ring and pinion gears to operate more quietly. As a result, a cast iron differential also requires less energy to operate, contributing to higher fuel efficiency. To the consumer, this means more miles between fill-ups.

My next car for sure. It looks great in black!

Nothing like a black car all shined up.

Having said that, make my white.

White looks good on the ATS. I saw a CTF ATS going the other way of me today, and it looked sharp. XTS looks great in white too.

Maybe I'll trade my V in for one. 2.0T, please...

How is the dash messed up?

It has angles and curves going every which way. Overall; sort of lumpy looking.
The center stack and the instrument hood stick out like an after thought.
The fake wood piece on the passenger side makes me queasy.
Also the door handles look like they will be awkward to the hand.

I think I'm getting queasy.

Don't try to judge the interior from this one photo. That is carbon fiber, not fake wood. The photo was obviously made with a wide angle or fish eye lens which could contribute to your assessment about the stack and instrument hood sticking out. Can't say about the door handles, but once again, better to judge in person than from such a distorted photo. ;)

The door handles look pretty damn close to the CTS ones, just a slightly different shape where it flares out at the end. Don't see that being much of an issue.

The stack in the CTS currently sticks out, it just doesn't dip down on the sides like the ATS. That seems to accentuate the stack but it's just a style thing. I'm not a huge fan of the upper area of the dash from that picture but it's better than being a flat board.

^ The doorhandles looks exactly like the ones on the SRX.

hates gonna hate.

but I don't like carbon fiber myself. I would much rather have fake wood. My preference would be piano black.

That is my favourite interior combo right there, Black/Cherry with either Carbon Fibre trim or Aluminum trim. Very nice!
