Hi - for a bit of Xmas holiday fun, took my 2013 507 Coupe to a Pistonheads rolling road day - pistonheads is a large UK based car website (www.pistonheads.com) and the day was a complete mixture of all different cars - the rolling road/dyno is dyno dynamics and the operator is a very well respected outfit in the UK (http://www.surreyrollingroad.co.uk) - they are not affiliated to any tuners and don't offer their own remaps - they are purely a dyno outfit.

Car did two runs, 504 and 507 bhp were the outputs (at the flywheel) and another print out shows 412.6 bhp (the same run but bhp shown 'at the wheel') - there was a P31 pre facelift saloon that put out 489 bhp (at the flywheel). A CLS63 produce 567bhp (atfw). Torque on my 507 was a little down with the max around 430 lb.ft but on the last run just around 425 (atfw).

I also put the car into dyno mode before the run.

Just thought I would post as a FYI since it was a 507 car.

I believe the new wet clutch gearbox transfers the power with less bhp loss.

Hence the better fuel economy...
