Vauxhall launches new common rail diesels

Vauxhall is launching a new 1.9 CDTi ECOTEC diesel engine in two power outputs – 120 and 150 hp for the Vectra and Signum models, and later this year, the new Astra. The new engines will be mated to a new six-speed gearbox, and bring Vauxhall's diesel range up to speed with the improved units on offer from rivals.

Both engines develop maximum torque between 2,000 and 2,750 rpm. The 120 hp engine produces up to 280 Nm while the 150 hp version develops 315 Nm of torque.

The two versions of the 1.9 CDTi are largely similar – with four cylinders, a turbocharger with variable turbine geometry and intercooler, but the 150 hp version has 16 valves.

The Vectra Estate and Signum will also feature a maintenance-free diesel particulate filter, for which Vauxhall will charge a £300 price premium. The 150hp version will cost £500 more than the 120 hp unit. Both engines are Euro 4-compliant, so will relieve company car drivers of the 3% BiK surcharge levied on the old DTi engines.
