The 360 hp drawn from the M133, two-liter four cylinder were apparently not enough for some of its customers, so the tuning specialists from Carlsson decided to comfort them by creating the Carlsson CCA 45 RSR.
From what we can tell from the official press release, Carlsson simply installed a version of the Carlsson C-Tronic CB Plug & Drive module instead of the original ECU, making the all-wheel drive AMG version of the baby-CLS to develop no less than 450 hp.
If you're not very good with arithmetics but still want to know why that figure is more than impressive, you should learn that it translates into 225 hp per liter.
The “regular” Mercedes-Benz CLA hasn't been left aside though, with a comprehensive array of aerodynamic components, sports exhaust, upgraded suspension, new light-alloy wheels and interior trim upgrades being available for the “four-door coupe.”
Similar C-Tronic CB performance kits are also available for the other gasoline engines in the range, as follows: the CLA 200 can deliver 187 hp and 300 Nm (221 lb ft) instead of the standard 156 hp and 250 Nm (184 lb ft) while the CLA 250's output is boosted from 211 hp and 350 Nm (258 lb ft) to a quite respectable 253 hp and 420 Nm (310 lb ft).
