Optional on the 328i but standard on the 335i are the Logic 7 Sound System, adding a speaker (for a total of 11 including the subwoofers), DSP and simulated surround sound ($1200); Dakota leather upholstery with a sun-reflective, surface heat-reducing treatment ($1550).
The Cold Weather Package ($750) is the same for both and comprises heated front seats, retractable headlight washers and pass-through trunk storage with cargo bag. The 328i Premium Package ($2650) includes a universal, remote, programmable garage/gate opener; auto-dimming interior and outside, power-folding mirrors; four-way, front-seat power lumbar; four-year, BMW Assist subscription; and the Dakota leather upholstery. The 335i Premium Package ($1550) matches the 328i's save the Dakota leather, which is standard on the 335i. Sport Packages (328i: $1200; 335i: $1300) add sport seats with adjustable side bolsters, a specially tuned sport suspension, increased top speed limiter (150 miles per hour vs. the standard, electronically limited 130 mph) and high-performance, run-flat, 225/40R18 front tires and 255/35R18 rear tires on 18x8.0 front and 18x8.5 rear alloy wheels with styles unique to each model.
Safety features include the usual array of front and side airbags, plus lower dash-mounted, anti-submarine knee airbags. Front seat belts have automatic pretensioners and force limiters, all four seating positions have three-point belts and adjustable head restraints, and rear seats are equipped with child safety seat footings and tether anchors (LATCH). Rear seats are also fitted with pop-up roll bars behind the head restraints that deploy in a fraction of a second when sensors detect signs of an impending rollover. The driver's feet get added protection from pedals that retract during a frontal crash and a dead pedal constructed to collapse under crash-force pressures. A tire-pressure monitoring system comes standard. Active safety features: ABS, Dynamic Stability Control, electronic brake-force distribution, DCS, brake drying, brake standby, start-off assist, and traction control. Optional is BMW Assist ($750), which automatically notifies a 24/7 communication center in the event of a serious collision and includes an SOS button. BMW Assist also incorporates Bluetooth technology, roadside assistance and telephone service reminders. Next Page
