GM Alpha 5-link rear suspension



Saw this at PRI last week but this picture is better than mine.

Looks an awful lot like e90/f30 suspension.

Except that looks like an LSD, something BMW cheaped out on long ago.

Are you suggesting that there are people that think the new GM cars are still being made with leaf springs?

True, like to believe the best in folks though. That's just funny. Leaf springs.

Wait, you mean the C7 too; it really does have leaf springs. I read GM is coming out with a El Camino C7 next year in celebration of the 50th anniversary of the El Camino.

LOL

Thank God they still use wheel studs. Had GM switched to wheel bolts, it would be am EXACT copy of the E90 suspension.

I had read when GM was developing this chassis they were using the e46 and e90 as a basis (in terms of handling and light weight). You can see how the arms are lightened.

What production car has BMW ever sold that could get around a race track faster than a C7 Z06 with its "antiquated" leaf springs and pushrod motor?

Yes, now M's have them, nothing else does. Been that way since the E46 left. Cheaping out, at the same time as giving cars more low end torque, just a bad approach.

I bought a year old ATS V-6 a year and a half ago. It is definitely not perfect but I was impressed by what I could get a year old one for and I got it with RWD, LSD, Magnetic Ride shocks, forged, staggered wheels, Brembo brakes. Ride/handling/braking is very good.

I don't care if a company takes an existing design and incorporates it on their car and also don't believe BMW was the first to develop a 5 link rear suspension. Believe front strut design is also very close to many other cars.

This,...

Quote:
To establish parameters around which they would design the ATS, GM engineers benchmarked the 1999-2006 BMW E46 3 Series, which ATS chief engineer Dave Masch and his team regarded as the most dynamic and driver-focused iteration of the 3 Series.[5] The engineers emphasized low weight when developing the ATS and their efforts resulted in a finished vehicle that weighs less than the BMW E46 benchmark.[4] To achieve this result, Masch suggested that the engineering team disregarded certain GM product development rules that, had they been followed, would have resulted in a heavier vehicle.[6]
