    Audi TT-RS, BMW F87 M2, and Porsche 718 Cayman S dyno, curb weight, track, and drag race shootout

    This is almost a fantastic comparison by Drivetribe. Why almost? Well, because the TT-RS is a dual clutch car and the BMW and Porsche are manual examples. That does not make this worthless by any means but the TT-RS has a major advantage and it certainly shows in the numbers.

    As the M2 and Cayman both have dual clutch options available this comparison would be much better served if the cars all had the same type of transmission. Why attempt to get these cars together only for there to be a gaping hole in the test?

    Let's start with what the cars weigh and their weight distribution:

    TT-RS: 3306 lbs 60f/40r
    M2: 3432 lbs 50f/50/r
    Cayman S: 3130 lbs 48f/52r

    Each car is heavier than its manufacturer claim. No surprise there. The M2 manages 50/50 weight distribution which is exactly what an M car is supposed to be. Keep in mind European figures are lighter than US figures due to crash test standards.

    The dyno testing is on a MAHA dyno which converts to estimated crank output. Each car is measured as underrated:

    The TT-RS is the most powerful and by a considerable amount although the M2 with its larger I6 engine offers the most torque. With all wheel drive and a dual clutch gearbox the TT-RS is going to decimate the other two in a drag race. That is exactly what happens:

    The M2 is the slowest of the trio. The Cayman does an impressive job with its four-cylinder 9A2B4 powerplant. Even if the M2 and Cayman S were dual clutch examples they still would lose although it would be closer. The M2 trailing the TT-RS by 3.6 seconds to 130 is an eternity.

    What happens on the track? The TT-RS is said to be a bit disappointing and that it does not quite offer the traction one would expect. The Cayman S has the most impressive chassis although the engine and brakes are discounted.

    The M2 is well balanced but the brakes are the weakest of the bunch. When will BMW get the brakes right? How many decades will it take? The M2 brings up the rear although it is said to feel better on the track than the TT-RS:

    The Cayman wins. The lightest car with the least amount of power rules on the track. A well balanced mid-engine layout certainly does not hurt. Was there really any doubt that it is the best sports car of the bunch?

    Has anyone had luck tuning the Cayman S yet? Really curious what they'll put down with some basic mods.

    Nice data point from a Cayman S owner: 3,060lb with a nearly full tank!

    Haven't even seen a dyno from one yet. They are going to be a nice tuning value though.

    Man, the latest tt-rs will prolly be the cheapest German speed daemon in straight line. With a minor tune and nothing else it already does 10.xx 1/4 mile on 93 octane Click here to enlarge.
