What's New for 2012:
- New entry-level trim model
- New base engine
The 2012 BMW Z4 is a 2-seat roadster with a power-retractable hardtop that tucks into the trunk. The Z4 is available in three trim levels: sDrive28i, sDrive35i, and sDrive35is. The base model comes standard with 17-inch alloy wheels.
The 2012 BMW Z4 roadster seats 2 passengers and provides 8 cubic feet of trunk space with the top up and less when the top is down. The base Z4 sDrive28i includes leatherette upholstery, air conditioning, an audio system with HD radio and CD player, and Bluetooth connectivity. The upgraded Z4 sDrive35i adds leather upholstery, power seats, and dual-zone automatic climate control. The top-of-the-line Z4 sDrive35is model includes upgrades to both the power seats and the interior trim.
BMW groups most of the Z4 roadster's options into packages, with the Cold Weather package adding heated seats and a heated steering wheel. The Premium Sound package includes a surround-sound audio system with satellite radio, while the Sport package includes sport seats, 18-inch wheels, and an adaptive suspension for the sDrive28i and sDrive35i models. Stand-alone options of note include wood interior trim, navigation system, and front and rear parking sensors.
