M4 versus ATS-V Coupe
Having a new ATS model line introduced in the small luxury sedan/coupe segment, Cadillac steps up competition with BMW in the top level of the segment.
V for Cadillac is what M is for BMW, which means both are pumped up with power and sports tuned. Both coupes are powered by 6-cylinder twin-turbocharged engines, and have rear wheel drive systems. But unlinke the M4, ATS-V Coupe is offered with an optional manual transmission.
On the paper, Cadillac's 445 lb-ft of torque and 455 hp accelerate the coupe from zero to 60 mph in 3.8 seconds, which is .03 seconds faster than M4's 0-60 time.
On the exterior both have about the same length and height, but the ATS-V Coupe is significantly narrower than the M4, which expresses more in the interior where passengers and the driver get less room compared to M4.
For the 2016 model year both coupes are priced in the same range; BMW starts from $65,700, while the Cadillac starts from $62,665.
