Bmw is introducing a mild facelift for the current generation Z4 roadster. The two-seater will be ready to reach showrooms as early as spring, after an official debut during 2013 Detroit Motor Show. 
 
The distinctive four round headlights team up with the broad BMW kidney grille to form a roadster-specific interpretation of the brand’s signature face. 
 
The headlights feature LED light rings which emit daytime driving light in the brand’s hallmark style. The integrated turn signal indicators have chrome-coloured surrounds.
 
A total of 11 external paint finishes are available for the new BMW Z4, including the new Mineral Grey metallic, Glacier Silver metallic and Valencia Orange metallic, which can only be ordered together with the Hyper Orange package.
 
On the inside, the bespoke Alcantara door panel trim, like the lower section of the instrument panel, comes in orange. The black leather seats have contrast stitching in Valencia Orange and an accent stripe running down the central section of the backrests and seat cushions. This stripe is likewise orange and is flanked by two thin white lines. The door panel trim and lower section of the instrument panel can also be specified in black as an option.
 
Along with the facelift, the Z4 Roadster also comes with a new petrol version, sDrive118i. The 4-cylinder, 2.0-liter turbocharged gasoline engine produces 156 hp and 177 lb-ft (240 Nm) of torque. As standard, the engine is connected to a 6-speed manual, but you can also opt for an 8-speed automatic transmission. The sDrive18i is able to return 34.6 mpg US (41.5 mpg UK or 6.8 liters / 100 km) in the combined cycle.
