Daehler Design & Technik GmbH are proud to introduce an upgraded BMW M4 Convertible packing significantly more power.
The open-top M4 is not exactly down on power, but this isn’t stopping tuners from working on the biturbo 3.0-liter inline-six engine. When it leaves the Regensburg assembly line, the car puts out a more than decent 425 horsepower and 406 pound-feet of torque. This ensures a sprint to 60 miles per hour (96 kilometers per hour) in 4.2 seconds with the optional automatic.
If you are thirsty for more power, Daehler Design & Technik GmbH will take the motor to 503 hp (375 kW) and 517 lb-ft (700 Nm). This will slash 0.2 seconds from the sprint and will also raise the top speed from an electronically-capped 155 mph (250 kph) to 196 mph (315 kph).
Go for the stage 2 kit and the output grows even further to 532 hp (397 kW) and 539 lb-ft (730 Nm). There’s no word about the 0-60 mph performance, but it’s probably around 3.9 seconds. We do know the maximum velocity in this case stands at a respectable 203 mph (327 kph).
Besides power packages, the open-top BMW can also gain 18-stage adjustable coilovers, high-performance brakes, stainless steel exhaust, and some very subtle aerodynamic tweaks.
Needless to say, the same updates are also available for the M3 Sedan and M4 Coupe.
