    That's why I've had a hard time with 3,400...
    Eliminating traditional assembly materials like molded plastic door panels, steel motor mounts and carefully selecting items like type of insulation, seat motors, batteries, etc.

    Mazda has done something similar with the Miata since its inception, fussing over the weight of everything from the muffler to the shift knob (which went through over 100 variations to find the lightest one possible that still gave good shift feel)

    “Low weight gives the ATS a more nimble and controllable feel, while also optimizing the performance and efficiency of the powertrains,” said David Masch, ATS chief engineer. “But we were careful to manage the weight while maintaining Cadillac’s signature levels of refinement.”

    Optimizing the ATS’s mass was the result of a four-pronged philosophy that included strict adherence to original architectural goals, measured load management throughout the vehicle, benchmarking components to see if lighter solutions were available and an overall culture that “weighed” the mass of every component in the car against all aspects of its development.

    An aluminum hood, magnesium engine mount brackets and even lightweight, natural-fiber door trim panels contribute to the ATS’s low overall mass – and reflect the systematic approach of evaluating every gram that went into the car. But some weight was deemed not only beneficial, but essential to the ATS’s driving experience. An example is the cast iron differential: Engineers found they could improve fuel economy with a cast iron differential rather than a lighter aluminum version.

    And while the rear suspension is mostly steel, the focus on load management and straight links enabled significant weight savings without using alternate materials. This helps offset the weight of the engine and transmission at the front of the vehicle, helping the ATS deliver its 50/50 weight balance, while also contributing to lower noise and vibration. A similar approach was taken on the wheels, where extra structural aluminum was strategically added to further reduce vibration.

    “We approached development by counting all the grams in the ATS,” said Masch. “We minimized them where we could and put them to the best use where they were needed.”

    I'm pretty confident the ATS will be very competitive in it's class. I do think they've got the weight right where it needs to be.

    Re: [Deliberate Misinformation] The Cadillac ATS is probably going to weigh about...

    Well, early returns and some car mag articles look good for the ATS. There are also some "analyses" out on the new 3 which have some bimmerphiles wringing their hands (plastic oil pan to save on weight, but what about heat, etc). I have been impressed that Cadillac did so well with the Alpha platform ATS coming in at 3400 lbs, even if this is some stripper model. Figure 3600 on most of those actually delivered and that is still not too bad. Looks like the ATS loses already to the 3 on interior room and trunk space, but we will have to see if that is much of a factor. My one significant dissapointment is that Caddy has opted to go to runflats for any model above the non-turbo 4. Go to any BMW message board and read all the wailing and moaning about runflats. On the new 3 the single biggest request for change was to get rid of the runflats (ride, noise, cost, handling, availability, etc, etc). Let's hope that Cadillac at least has them as a "delete" option. Can't wait for some actual car mag evaluations and some comparos with the 3, A4, etc.

    Thats what I suspected. A TTV6 should weight awfully close to the LS V8's...

    I would say a TTV6 would be heavier...

    Looking at the first gen CTS vs the V, the V was a couple hundred pounds heavier and had more front weight bias.

    I know that was part of it, but I don't think even that was enough.

    Well, since an LS6 and T56 weigh about 450lbs, I think you need to look elsewhere for the additonal weight.

    Again, a V6, with DOHC running gear AND 2 turbos hanging off of it, with the additional coolers and accessories, will be heavier than an LS engine...
