C400 with Kleemann Kbox. Running sick 0-60 times.
Just got new Gtech pro SS 50 Hz GPS (uses 1 ft rollout standard), and have been messing around with it. Did 7 runs so far have and been getting low 4s.
Today after cleaning my dirty air filters ran 3.84s 0-60. Have otherwise stock c400 with k&n filters and kbox piggy back. 93 octane, 47F outside, brake torque to 2.5K rpm.
Posted some photos of the best run.

Haven't weighed the car yet but my understanding is the acceleration runs only rely on GPS signal. I will weigh it in the near future to do some hp/tq runs, although I'm not sure what the accuracy is. Most magazines are getting 4.6-4.8s 0-60 times, but its not clear whether they use rollout (zero-60times.com does NOT and their best run was 4.7). I wouldn't be surprised if this is what you see stock (depending on conditions and launch technique). Tuned, Im getting 4.0-4.2 very consistently with a very mild launch technique (2000-2500 rpm), so if you account for rollout (on average add 0.3 seconds because the 4MATIC hooks up instantly) Im probably running 4.3-4.5s from a standstill (0.4-0.5 seconds better than stock). The run I posted felt amazing and I don't anticipate consistently running this fast, especially when the temps outside get to 80-90F and the turbos start struggling to build up boost.
