BMW Introduces New 1 Series Coupé; Twin-Turbo 4-Cylinder Diesel Model
3 July 2007
|The 1 Series Coupé.|
BMW has expanded its 1 Series with a new Coupé model that offers a choice of three versions: the 120d, 123d and 135i.
Both the 123d and the 135i are weighted toward power and performance; the 123d marks the production application of the world’s most powerful four-cylinder diesel engine, and the 135i marks the first time a twin-turbo gasoline engine has powered a 1 Series car. The 123d diesel delivers fuel consumption of 5.2 l/100km (45 mpg US) and CO2 emissions of 138 g/km.
The 204 hp (153 kW) 2.0-liter diesel in the 123 is the world’s first all-aluminium diesel to have an output per liter figure in excess of 100 hp. It is also the first four-cylinder production diesel to come with twin-turbo technology.
Peak torque is 400 Nm (295 lb-ft) from 2,000 rpm, while the engine revs to in excess of 4,400 rpm where peak power is attained. This performance equates to a zero to 62 mph time of 7.0 seconds and a top speed of 148 mph—previously unheard of figures in such small capacity production diesels.
The 2.0-liter engine in the 120d produces 177 hp (132 kW) of power; 350 Nm (258 lb-ft) of torque; and a zero to 62 mph time of 7.6 seconds with fuel consumption of 4.8 l/100km (49 mpg US) and CO2 emissions of 128 g/km.
Both the 123d and 120d come with Auto Start-Stop technology, Brake Energy Regeneration, third-generation common-rail fuel injection, a diesel particulate filter, active aerodynamics, Electric Power Steering and low rolling resistance tires to aid in fuel efficiency.
The high-end 135i uses a six-cylinder 3.0-liter twin-turbocharged gasoline engine that produces 306 hp (228 kW). The 135i is capable of accelerating from zero to 62 mph in 5.3 seconds before going on to an electronically-limited top speed of 155 mph. The engine develops peak torque of 400 Nm (295 lb-ft) from just 1,300 rpm.
The 135i has a fuel consumption rating of 9.2 l/100km and CO2 emissions of 220 g/km.
