BMW Z4 2011 News

BMW has given the Z4 Roadster a modest external freshen up, and added an eight speed auto transmission as standard to four-cylinder variants. In what is the latest in a string of pricing and specification updates for various BMW models, the Z4 refresh doesn’t extend to engine tweaks, but the two turbo-charged four-cylinder variants – the Z4 sDrive20i and Z4 sDrive28i, pick up that eight speed auto as standard. If you prefer to opt for a manual transmission, you will be pleased to hear that BMW won’t charge you any extra for a six-speed manual gearbox. On close inspection you may, or may not, notice the external changes, but they include; LED light rings around the now standard Bi-xenon headlights, new accent lights with metal inserts over the headlights, Chrome coloured surrounds on the turn signal indicators and a newly designed side indicator surround. Inside the cabin BMW has added high-gloss black surrounds around the central air vents and folding control display of the Z4 Roadsters iDrive system. Equipment upgrades include the addition of ‘Professional’ grade navigation system as standard. This system includes a high-resolution 8.8-inch colour display, DVD drive, functional bookmarks, 3D map and arrow display and bird’s-eye view. The Z4 sDrive28i picks up new 18-inch wheels, sports seats, internet functionality and a music interface for smart phones. And the top of the range Z4 sDrive35is receives new 19-inch wheels (up from 18-inch), wind deflector, internet functionality and a music interface for smartphones.

BMW in the US yesterday unveiled its new turbocharged 2-litre petrol engine that is claimed to have the performance of a six with the economy of a ... well, four.Proposed initially for the X1 - and to be badged xDrive28i - in Europe later this year, the turbo is also bound for the entry-level Z4 and selected 1-Series and 3-Series vehicles.BMW Australia spokesman Piers Scott says it's coming, but it is still being determined when it arrives and in what model."It may not be the X1 that's first in Australia with this engine," he says. "Production scheduling could see the four-cylinder Z4 getting here first."The twin-scroll turbo four pumps 180kW and 353Nm of torque - more torque than the company's 3-litre atmo six that has 190kW/310Nm.It is the first time that BMW has launched a production turbo-four since the 2002 of 1974.The engine delivers its power at 5000rpm, 1500rpm lower than the peak power of the six, and the 353Nm of torque hits at 1250rpm - again, 1500rpm earlier than the six.BMW says the four-cylinder engine has an aluminum crankcase so is lighter and smaller than the 3-litre six. Its compact size will allow it to be placed at the back of the engine bay to improve chassis balance.The result of increased performance also comes with lower fuel consumption and emissions, though BMW is yet to release details.
