German tuning specialist Daehler Design & Technik GmbH has officially introduced its own take on the set of upgrades that best fit the BMW M4 Convertible.
Roadsters will be back in fashion once the winter clears out – after all connoisseurs know convertibles are best used during the calm spring and autumn days – and Daehler Design & Technik GmbH has decided to treat us to their own interpretation of the M4 that can make do without its top on. The regular M4 Convertible is not your Average Joe when it comes to displaying performance capabilities but the German specialists nevertheless decided that more power is always a good idea. So they worked some engineering magic on the biturbo 3.0-liter inline-six engine and went on from the regular 425 horsepower and 406 pound-feet of torque (good for a 4.2 seconds sprint to 60 mph) to the first stage – 503 hp (375 kW) and 517 lb-ft (700 Nm). This mod is enough to shave off 0.2 seconds off the aforementioned sprint time and also enable an unrestricted top speed of 196 mph (315 kph).
If the owner is still dissatisfied with the figures he received there’s always the option to bump everything up with the second stage kit, ask which enables a total output of 532 hp (397 kW) and 539 lb-ft (730 Nm). This time around the run time to 60 mph is unspecified but we’re betting for a hair below those magic four seconds. The maximum speed is now also above the 200 mph threshold – at 203 mph (327 kph). Modifications also include some aerodynamic updates, site 18-stage adjustable coilovers, treatment better brakes or a stainless steel exhaust – and all the upgrades can also be had if you chose the M3 sedan or the regular M4 Coupe.
