Opel Astra 1.3 CDTI features a BV turbocharger from BorgWarner Turbo Systems.
The start of production of the new 1.3-litre CDTI common-rail turbodiesel engine also sees the launch of the smallest version of the new BV generation of VTG (variable turbine geometry) turbochargers from BorgWarner Turbo Systems. With this new system, the turbocharger specialist from Kirchheimbolanden is expanding its product range of VTG turbochargers for especially small and powerful diesel engines, thus once again underlining its technological lead in this field.
Powerful yet refined and economical is how the modern 1.3-litre CDTI common-rail turbodiesel engine presents itself in the new Opel Astra. The compact diesel power unit with variable turbine geometry from BorgWarner Turbo Systems is celebrating its debut at this year’s RAI motor show in Amsterdam. With 200 Nm of torque and a fuel consumption of just 4.8 litres per 100 km, the 66 kW (90 bhp) version offers impressive performance, economy and environmental friendliness. GM Powertrain in cooperation with Fiat developed the 1,248 cc four-valve engine, which caused quite a stir two years ago in the Opel ECO-Speedster when Opel engineers set 17 sensational world records with the new engine on the test track.
The series launch of the 1.3-litre CDTI soon followed in the Opel Corsa, Tigra, and Combo models, as well as in several Fiat vehicles. In contrast to the 52 kW (70 bhp) basic version, the new engine in the Opel Astra has a BorgWarner turbocharger with variable turbine geometry. The Type BV35 turbocharger system raises torque from 170 to 200 Nm, with maximum torque already available from 1,750 to 2,500 rpm.
The world’s smallest four-cylinder common-rail turbodiesel develops its maximum power output at 4,000 rpm, making the 90 bhp CDTI one of the most powerful engines in its class.
