|The WTCC Ultra diesel concept|
Chevrolet Europe is introducing a diesel racecar study—the WTCC (World Touring Car Competition) Ultra—at the Paris Motor Show this fall. The ready-to-drive concept car, developed by a GM team around the globe, is the optical vision of a new touring car generation, and features a 190 hp (142 kW) diesel engine.
Chevrolet Europe is also unveiling its second production diesel vehicle—the new Chevrolet Epica Diesel, which will be launched in spring 2007. The mid-class sedan is powered by a 2.0-liter common rail diesel, also used in the earlier announced Captiva Diesel compact SUV. (Earlier post.) The Captiva Diesel goes on sale this fall.
The 2.0-liter diesel in the Epica delivers 110 kW (150 hp) of power and 320 Nm (236 lb-ft) of torque at 2,000 rpm. Mated with a manual five-speed gearbox, it can optionally also be paired with a five-speed automatic transmission. The Epica Diesel accelerates from 0-100 kph in 9.7 sec (manual) and has a top speed of 201 kph (125 mph).
Fuel consumption for the Epica Diesel is an estimated 6.1 liters/100km (39 mpg US) for the manual, and 7.7 l/100km (31 mpg US) for the automatic.
The engine features a 1,600-bar common rail injection system from Bosch. Among the other technical characteristics of the SOHC unit are the aluminium cylinder head, a balance shaft and a variable geometry turbocharger (VGT).
The 2.0-liter diesel engine was developed jointly by GM Korea and GM Powertrain, and is produced in Gunsan/South Korea. The diesel engine plant was built in the immediate vicinity of one of GM Korea's three Korean vehicle factories, and production began in March 2006. Up to 250,000 engines a year can be produced at the 19,200 sq.m. facility.
