Although diesel-powered cars have come under major scrutiny even in Europe, Opel has rolled out its range-topping oil burner for Europe. The entire Opel Insignia range will now be available with a 2.0-liter BiTurbo four-cylinder diesel engine.
With the range-topping diesel engine, all-wheel drive and an eight-speed automatic is standard across the Insignia Grand Sport, Sports Tourer and Country Tourer. Final performance figures for the 2.0-liter BiTurbo are 210 horsepower and 354 pound-feet of torque.
The engine features two turbos working sequentially to maximize performance and reduce fuel consumption. VGT vanes increase low-end torque and provide power at higher engine speeds. The engine is paired with Opel’s selective catalytic reduction exhaust after-treatment to remove NOx from tailpipe emissions.
Opel says it also worked to curb the vibrations notoriously associated with diesel engines. To counter any new vibrations, the 2.0-liter BiTurbo engine features a cast-iron crankshaft, balance shafts, a stiffened flywheel and a two-piece oil sump. For greater efficiency, the water pump only activates when the temperature requires it.
The new diesel engine will make its debut with the Opel Insignia lineup at the 2017 Frankfurt Motor Show. The first production units are expected to roll off the assembly line at the end of summer.
