BMW UNLEASHES Z4 SDRIVE35IS WITH M UNDERTONES

BMW keeps saying they are not going to produce a Z4 M based on the new roadster, but we keep hearing whispers that something is quite possible depending on market demand. For now though fanatics can take solace in this brand new Z4 sDrive35is which comes standard with the M Sports Package.

Visual differences from the standard cars include a new front bumper that looks straight out of M Division, silver side mirrors, matt aluminium outer air intakes, 18-inch light alloy wheels (there are optional 19s available), new rear bumper, two-piece rear diffuser and a sportier exhaust note. The suspension has been lowered by 10mm so as to improve handling and balance.

Engine-wise BMW stayed with the 3.0-litre twin turbo motor already doing duty in the Z4 sDrive35i but made a few changes. The two turbos are made from special steel and each one pumps compressed air into three cylinders.

Basically those changes have resulted in power hikes that put the car on par with the previous-generation Z4 M but give it much more torque. It produces a hefty 250kW at 5800rpm (just 2kW less than the old 3.2-litre powered Z4 M) and a massive 450Nm of torque between 1400rpm and 4500rpm. Wait, there’s more. During short bursts of time an overboost function kicks into place and kicks out 500Nm! They say the Z4 sDrive35is will run from 0 – 100km/h in just 4.8 seconds (as quick as the M3) and stop running at 250km/h. Putting all power and torque on the rear axle is the trusted 7-speed double clutch gearbox.

Apart from the M exterior the interior is also M-style with an M-badged steering wheel, entry strips, gearlever knob and aluminium carbon on the dash. Other lesser Z4s will also have access to the M Sport Package (but without the special engine of course).

BMW will present the new car at the 2010 North American International Auto Show (NAIAS) in Detroit in just over a month’s time. It may be at least six months before Mzansi people get their hands on it. Prices should start at around R800 000.
