German based BMW Group tuning specialist Hartge first showed us off-the-shelf parts for the 1-Series coupe when it was first released, and then shortly followed with the aerodynamics kits. Now Hartge have developed an ECU upgrade for BMW’s already potent 3.0-liter bitrubo engine in the 135i coupe releasing an additional 44hp.
The result is a total of 350hp at 5660 rpm and 480 Nm (lb-ft 354) at 2950 rpm. The sprint from 0 to 100 km/h (62 mph) arrives in 4.8 seconds – a half second faster than its standard 5.3 seconds. Also, an unrestricted top speed allows 280 km/h (174mph).
Hartge states that a 135i fully equipped with the entire suite of components will cost in Germany € 48,162.14, excluding VAT. See press release below for more details.
