Dream Team: New Top BiTurbo Diesel Engine for Opel Insignia Flagship

• Really strong: Sequential turbocharging for 154 kW/210 hp and high torque
• Ideal combination: Always with eight-speed automatic and all-wheel drive
• Very efficient: Combined NEDC fuel consumption 6.9 liters, equivalent to 183 g/km CO₂
• Made in Germany: Engine from the Kaiserslautern plant for all Insignia variants

Dream team: The new top-of-the-line 2.0-liter diesel engine for the Opel Insignia BiTurbo always comes with all-wheel drive and eight-speed automatic transmission.

Production-start for the new top-of-the-line engine and the Opel Insignia Country Tourer from Opel: With the summer slowly drawing to an end, the first 2.0 liter BiTurbo diesel engines will roll off the production line. They are tailored for the Country Tourer along with all other variants of Opel’s flagship. With the Grand Sport, Sports Tourer and Country Tourer the second generation Insignia can be ordered with the new top-of-the-range diesel this year. The Country Tourer appeals to all Insignia fans looking for stylish and practical station wagon with off-road looks. The newcomer will celebrate its world premiere at the Frankfurt International Motor Show (September 14-24).

The newly designed 2.0-liter diesel engine produces 154 kW/210 hp at 4,000 rpm and develops strong torque of 480 Nm from only 1,500 rpm thanks to sequential two-stage turbocharging (Official fuel consumption Grand Sport 2.0 BiTurbo in accordance with New European Driving Cycle: urban 8.7 l/100 km, extra-urban 5.7 l/100 km, combined 6.9 l/100 km, official specific combined CO₂ emissions 183 g/km). The new Insignia BiTurbo accelerates from 0 to 100 km/h in just 7.9 seconds with a maximum speed of 233 km/h.

Such strength must be transferred to the road intelligently, which is why the top-of-the-line engine always comes in combination with a smooth-shifting eight-speed automatic transmission and high-tech all-wheel drive with torque vectoring. In addition to the power output, the drivability (turbo power in every situation) and the refinement of the new common rail engine are also further improved compared with the existing extremely popular 2.0 liter unit with single turbocharger (125 kW/170 PS; official fuel consumption Grand Sport with front-wheel drive in accordance with NEDC urban 6.7 l/100 km, extra-urban 4.3 l/100 km, combined 5.2 l/100 km, official specific combined CO₂ emissions 136 g/km).

In addition to the legally required NEDC Data, Opel also determined values in accordance with the Worldwide Harmonized Light-Duty Vehicles Test Procedure (WLTP) which are officially required as of this autumn for the newly developed four-cylinder BiTurbo. The WLTP values (Insignia Grand Sport 2.0 BiTurbo WLTP fuel consumption range 12.2-6.2^[1] l/100 km, combined 8.0-7.5 l/100 km, 209-196 g/km CO₂) are much more realistic than the hitherto officially applicable NEDC figures (Official fuel consumption Grand Sport 2.0 BiTurbo in accordance with NEDC urban 8.7 l/100 km, extra-urban 5.7 l/100 km, combined 6.9 l/100 km, official specific combined CO₂ emissions 183 g/km). The WLTP figures also take different driving styles into consideration, which enables customers to get a better estimate of their own fuel consumption^[2]. An overview of the more realistic consumption figures in accordance with the WLTP cycle can be found on opel.de.

Like the existing 125 kW/170 hp 2.0 liter engine with single turbocharger, the new top-of-the-line diesel also features highly effective Selective Catalytic Reduction (SCR) exhaust after-treatment technology with AdBlue injection, which removes nitrogen oxide (NOx) from the engine’s exhaust gases. The watery urea solution which contains ammonia (NH₃) reacts with the nitrogen oxides in the SCR catalytic converter and creates harmless nitrogen and water vapor.

New top-of-the-line diesel with sequential two-stage turbocharging

Opel has pulled out all the stops for maximum fuel efficiency and maximum fun-to-drive. The new diesel features two turbochargers functioning sequentially. The intake air enters the first turbocharger where it is compressed and passed to the second turbo. This is driven by Variable Geometry Turbine vanes in the exhaust gas, which increase torque at low engine speeds and raise power at higher engine speeds. VGT then adjusts the vanes to parallel with the gas flow, thus reducing back pressure and lowering fuel consumption. The now highly compressed and very hot intake air then passes through an intercooler on the way to the combustion chambers. Diesel fuel is then injected through seven-hole jets in up to ten sequences at 2000 bar. The boost-pressure is controlled, according to engine-speed and load, by three bypass valves and an electrically actuated variable turbine geometry.

Apart from increased efficiency, higher power output and torque, refinement and noise attenuation were priorities in the design of the new engine. The Opel engineers therefore gave the engine a cast-iron crankshaft, balance shafts, a stiffened flywheel and a two-piece oil sump, in order to reduce diesel-typical vibrations and acoustics to a minimum. In order to further lower fuel consumption, the water pump is only switched on when temperatures require it. Just like the well-known 2.0 liter diesel, the new BiTurbo diesel is built in Opel’s Kaiserslautern plant.

Power of two turbos: BiTurbo diesels now with Opel Astra, Insignia

A 2.0 liter BiTurbo diesel with 143 kW/195 hp and maximum torque of 400 Nm already made its debut in the first-generation Insignia in 2012, and was then offered in the Astra, Cascada, GTC and Zafira Tourer. 

The new 154 kW/210 hp and 480 Nm engine for the Insignia fits perfectly into the range of current Opel power units with two-stage turbocharging.

Opel Astra, the European Car of the Year 2016, is available as hatchback and Sports Tourer with a 118 kW/160 hp 1.6 BiTurbo. The four-cylinder engine develops maximum torque of 350 Nm at only 1,500 rpm (Official fuel consumption Astra hatchback in accordance with NEDC, urban 5.0 l/100 km, extra-urban 3.4 l/100 km, combined 4.0 l/100 km, official specific combined CO₂ emissions 106 g/km CO₂). The fastest Astra diesel thus accelerates from zero to 100 km/h in 8.9 seconds and reaches a maximum speed of 220 km/h.
