Closer Than Anticipated
Just a few hours ago, we made known BMW’s ambition to produce the upcoming line of combustion engines, including fresh diesel motors for its European SUVs. Though diesels are not frequently sought in the U.S., specifically concerning anything else than commercial vehicles, on the European continent numerous BMWsports coupes have diesel engines too.
The 4 Series range is no exception. Previous models and the current version include a 3.0-liter, turbocharged inline-six diesel engine which is highly fuel-efficient and robust. Moreover, it has tremendous tuning capability, even with minimal hardware alteration. The motor on the classic motor car featured in this Carwow video, however, had additions such as new cams, intercoolers, turbo, exhaust system, and retuned software.
The outcome of all the alterations leads to 462 horsepower, representing a considerable increment from the origin 260 hp. The peak torque is remarkable – comprising 750 pound-feet (1,017 Newton-meters), nearly two times the manufacturing count. In comparison, the M4 maintains no adjustments to its engine, implying it possesses a 3.0-liter inline-six gasoline turbo with 510 hp and 479 lb-ft (650 Nm) of torque.
The current installation of the M4 features an eight-speed automatic gearbox with launch control, distinctly departing from its predecessor which lacked this support. Similarly, both vehicles run on rear-wheel drive, though that’s where the similarities end. Turning to affordability and lightweight components, the 4 Series is much more economically pleasing and effective while it can’t go toe-to-toe with the top tier Bavarian coupe. This lack of correlation is to be expected though.
Given the intense force transferred solely to the back tire – and a slippery race track – it can be quite challenging for the 4 Series to acquire adequate traction over the initial ordeal. Nonetheless, the electronic stability system parameters are altered for the succeeding completion, providing a more reliable gripping structure across the competition. Might such shifts be sufficient to outperform the M4 in its purest form? Let’s determine this by viewing the video above!
