The BMW 1 Series was introduced for 2008. Though it’s the company’s least expensive model, it’s hardly an underperforming stripper. The base-model 128i comes with a naturally aspirated 3.0-liter inline-6 producing 228 horsepower. The performance-oriented 135i comes equipped with BMW’s impressive turbocharged 3.0-liter inline-6. It produces 300 hp and 300 pound-feet of torque. Both engines come with a six-speed manual as standard equipment; a six-speed automatic transmission is available as an option. In the convertible, a fully automatic cloth top stores underneath a hard tonneau cover.
Although no official word has been given regarding blessing the BMW 1 Series with an “M” model to call its own, the 135i does get plenty of M-like tweaks to sweeten the deal: an exterior aero kit, special sport seats and pedals, and a sport suspension including 18-inch wheels and performance run-flat tires. Rumors of a limited “tii” edition intended to pay homage to the original BMW 2002tii model persist.
Measuring 171.7 inches in length and 76.1 inches in width, the 1 Series checks in about 8 inches shorter and 2 inches narrower than the 3 Series coupe. The rear seat is strictly for two, and how often it gets used depends on how large and how forgiving potential rear passengers are. There’s not a lot of space in back, so it’s almost better to consider the 1 as having a 2+2 seating arrangement — especially the convertible.
In our initial reviews, our editors have offered nothing but praise for the 135i’s engine, citing powerful acceleration from just off idle all the way to redline. The steering is responsive in typical BMW fashion. And thanks to idealized weight distribution, the 1 Series handles admirably, though drivers expecting the car to act like a mini M3 will likely be disappointed, as the suspension is tuned to prioritize comfort and ride quality.
