Both the 135i and 135is are available in coupe and convertible format and they share two optional packages – the Premium Package and the Technology Package. The Premium Package adds in auto-dimming mirrors, Comfort Access keyless entry, rearview-mirror-mounted compass, SiriusXM radio, ambient lighting and garage door opener. The Technology Package includes voice control, navigation with real-time traffic, BMW Assist with Bluetooth, smartphone integration and BMW apps.
The 135i has two exclusive optional packages – the Cold Weather Package and M Sport Package. The Cold Weather Package includes a heated steering wheel and front seats. The M Sport Package adds in an M Sport leather steering wheel with paddle shifters, 18-inch light-alloy wheels in a double-spoke style, 150 mph top speed, anthracite headliner, Shadowline exterior trim, sport seats and four interior trim options – Glacier Silver, Alpine White, Anthracite Wood and Light Burl Walnut.
In terms of competition, there are really not too many direct competitors for the 135i and 135is, but there are a few vehicles that can be considered alternatives. The first alternative would be the 2013 Audi A5, which comes standard with a 2.0-liter engine with 211 horsepower, a six-speed manual transmission and a 10-speaker premium sound system. Next up is the 2013 INFINITI G Coupe, which comes standard with a 3.7-liter V-6 engine that produces 330 horsepower, a seven-speed automatic transmission with manual mode, and a 5.7-second 0-to-60 sprint. Last on the list is the 2013 Mercedes-Benz C350 Coupe, which features a 3.5-liter V-6 engine with 302 horsepower, a 5.6-second sprint to 60 mph and a sport-tuned suspension.
The competition for the BMW 135 is pretty spread out, but the alternatives are available and very closely matched to this relative newcomer.
