S they are already icons of BMW M history. The M3 CLS (E46), M3 GTS (E92) and M4 GTS (F82) models. The tuning company G-Power has now taken on them and seasoned them powerfully. The naturally aspirated engines of the two M3 models each have their own compressor system. The increase in performance on the BMW M4 GTS was achieved with the help of a combination of chip tuning - i.e. the reprogramming of the engine control unit - and an optimization of the exhaust system including the turbocharger with more capacity.
The results are very sporty. The BMW M3 CSL (E46) with a 3.2 liter in-line six-cylinder and supercharger system now has 475 hp and 470 Newton meters. The M3 GTS (E92), which is powered by a 4.0-liter V8 high-speed engine (also with a supercharger system), now puts 650 hp and 630 Newton meters on the road. The 3.0-liter in-line six-cylinder of the BMW M4 GTS (F82) delivers 30 more PS, i.e. 680 PS and 860 Newton meters, thanks to Performance Software V4, a new exhaust system and new turbos.
