As well as the 20i's extra features and new styling details, the 28i also moves up from 17-inch alloy wheels to 18-inch alloys in a new design. The price of the 28i mid-range variant has dropped $100 (from $90,000 to $89,900). In addition, the 20i is now also fitted with BMW's Navigation system Professional.īMW claims that the overall improvement in value for the facelifted 20i variant is roughly $6500. BMW argues the increase has been more than offset by the ZF eight-speed automatic transmission (formerly a $3500 option) now being standard equipment. Of the three, only the base-grade 20i has increased in price (from $75,500 to $77,900). Turbocharged four-cylinder engines power the first two variants and the sDrive35is has a twin-turbo inline six under its bonnet. The Z4 range comprises three distinct models, the sDrive20i, sDrive28i and sDrive35is. The upgrade is part of a program to promote value across the entire BMW product portfolio. Two years later, the best BMW can offer local buyers is a lightly facelifted car with the outstanding ZF eight-speed automatic transmission now standard with the four-cylinder models. But if the Z isn't an all-new model – and isn't even a significant upgrade – at least it benefits from the turbocharged four-cylinder engines introduced to the sports car in 2011.

While the first-generation Z4 (coded E85) ran for six years, the GFC ensured that more recent models have had to carry on through longer life cycles. Simply, BMW wasn't in a position to rectify a styling or engineering mistake – not at a time when automotive R&D projects were being put on hold all around the world. Introduced in the year following the GFC and being a niche-volume model, the second-generation Z4 had to be a strong concept. ✔ Instrument cluster warning light explanation.BMW Z4 sDrive20i, sDrive28i and sDrive35isīMW's Z4 has been on sale in its current (E89) form since 2009.Critical vehicle information listed in the BMW owner's manual: Listed below are some of the top reasons to keep a copy of your vehicle's owner's manual handy under your ownership.
