2008–2014 BMW 1 Series 123d Cabrio Specs & Performance

The 2008–2014 BMW 123d Cabrio is a compact diesel convertible powered by a 2.0-liter bi-turbo inline-four engine producing 201 hp and 295 lb-ft of torque. The N47D20 engine uses DOHC, 16 valves, and common-rail fuel delivery, with peak power arriving at 4,400 rpm and peak torque at 2,000 rpm. Its rear-wheel-drive layout is available with either a 6-speed manual or 6-speed automatic transmission. With a 17.7 lb/hp power-to-weight ratio, the 123d Cabrio accelerates from 0 to 60 mph in 7.3 seconds and reaches a top speed of 143 mph.

The BMW 123d Cabrio combines its efficient bi-turbo diesel drivetrain 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 13.5-gallon fuel tank. MacPherson struts at the front and multi-link suspension at the rear are paired with vented disc brakes and 205/50R17 V tires. AutoSpecsHub lists combined fuel economy at 43.5 mpg, a total range of 586 miles, and tailpipe CO2 emissions of 232 g/mile. Compared with the 123d Coupé, the Cabrio retains the same 201-hp, 295-lb-ft N47D20 engine and rear-wheel-drive layout, but its convertible body brings a 10.8 ft³ luggage capacity and a lower 43.5 mpg combined economy.
