2013 facelift for BMW Z4 & new Z4 M35i

BMW are planning to facelift the Z4 for 2013 and add a new M Performance model – the BMW Z4 M35i – to replace the Z4 sDrive35iS. Four years since the current BMW Z4 was launched at the Detroit Motor Show in January 2009, it looks like BMW’s roadster is getting a facelift to keep it fresh, and a new M Performance model – the BMW Z4 M35iS. Changes to the 2013 Z4 are likely to be modest, with the usual facelift fare of new bumpers, new lights, new alloys, titivated ‘more upmarket’ interior and tweaks to the engines to offer more power with better economy and lower emissions.
