The 2008–2014 BMW 118i Cabrio is a compact convertible powered by a naturally aspirated 2.0-liter inline-four gasoline engine producing 141 hp and 140 lb-ft of torque. The N43B20 engine uses DOHC, 16 valves, and direct injection, with peak power arriving at 6,000 rpm and peak torque at 4,250 rpm. Its rear-wheel-drive layout can be paired with either a 6-speed manual or 6-speed automatic transmission.

The BMW 118i Cabrio combines its naturally aspirated gasoline engine with a four-seat open-top cabin and 10.8 ft³ of luggage space. It measures 171.7 inches long, 68.8 inches wide, and 55.6 inches high, with a 104.7-inch wheelbase and a 14-gallon fuel tank. MacPherson struts at the front and multi-link suspension at the rear are paired with vented disc brakes and 195/55R16 V tires. AutoSpecsHub lists combined fuel economy at 37.3 mpg, a total range of 522 miles, and tailpipe CO2 emissions of 240 g/mile. Compared with the 120i Cabrio, the 118i uses the same 2.0-liter N43B20 engine family but produces less power and torque, while its lighter 3,263-pound curb weight contributes to its efficiency-focused character.
