While it seems unlikely the U.S. will receive a diesel option once the 2016 Buick Cascada arrives on our shores, the 2015 Opel Cascada marches forward with the latest diesel engineering from Opel. Opel has announced the new 2.0-liter CDTI turbo-diesel may now be had. The engine replaces the outgoing 165 hp diesel, delivering 14 percent more torque.
The previous diesel engine served up 165 hp, while the new 2.0-liter turbo-diesel squeezes out an additional five horsepower. Combined with the 2015 Cascada’s 295 lb-ft of torque, the new engine scoots the soft-top convertible from 0-62 in 10.3 seconds. Nothing to snap your neck, but brisk, nonetheless. Consumers looking for diesel power will be impressed with its efficiency, however.
By redesigning the combustion chamber, optimizing the re-profiled intake ports and looking to a new fuel injection system with 2,000 bar and adding up to 10 injections per cylinder cycle, the previously Euro-6 compliant diesel engine is now six percent more efficient, sipping its diesel fuel more delicately than ever.
Opel engineers also ensured a smooth driving experience, as diesels tend to transfer more NVH (noise, vibration and harshness) while driving. To counter this, the top, and bottom, of the engine were looked at specifically. A new aluminum cylinder head including the addition of a decoupled, plastic cam cover with isolated fixings and a sealing gasket, improves noise attenuation. At the bottom, a newly designed balancer-shaft module is put in place, also made of aluminum.
Through these engineering tweaks, the engine is now three decibels quieter than the outgoing diesel engine.
The new engine may also be had with a manual gearbox, for those looking to wring every bit of performance possible out of the new 2.0-liter diesel. The new diesel engine is available now for the 2015 Cascada.
