2007–2014 BMW 1 Series 123d Coupé Specs & Performance

The 2007–2014 BMW 123d Coupé is a compact diesel performance coupe 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 diesel fuel delivery, with peak power arriving at 4,400 rpm and peak torque at 2,000 rpm. Its rear-wheel-drive layout is paired with a 6-speed manual transmission, allowing the 123d Coupé to accelerate from 0 to 60 mph in 6.8 seconds and reach a top speed of 148 mph. With a 3,296-pound curb weight and a 16.4 lb/hp power-to-weight ratio, it combines strong low-end torque with the efficiency expected from a diesel-powered BMW coupe.

The BMW 123d Coupé also offers a compact four-seat cabin and 13.1 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 complemented by vented disc brakes and 205/50R17 V tires. AutoSpecsHub lists combined fuel economy at 45.2 mpg, a total range of 609 miles, and 198 g/mile of tailpipe CO2. With its bi-turbo diesel engine, rear-wheel drive, and strong 295 lb-ft torque output, the 123d Coupé stands apart from the gasoline-powered 1 Series Coupé models in the same lineup.
