General Motors, through its Opel/Vauxhall division has confirmed that they will launch at least three new engines over the next 12 months. The first new of the family is a gasoline-burning 4-cylinder ECOTEC engine with precisely 1,598 cubic centimeters of displacement – a figure that equates to 97 cubic inches. The exhaust manifold of the engine is given a turbocharger to boost its power and performance.
As we expected, in the development phase, the engineers of Opel put a big emphasis on cutting carbon dioxide emissions and raising fuel economy but without sacrificing power. Better fuel economy of the engine is partly reached by fitting the engine with what calls as Spark Ignition Direct Injection (SIDI). Actually, the system has already applied in several other products from General Motors around the world, including the Cadillac SRX, the Chevrolet Equinox and the GMC Terrain. The carbon dioxide emissions are reduced significantly also because of the existence of start/stop system that will be given as standard equipment in all Opel’s future models.
However, specific fuel economy ratings were not announced, as they will vary greatly depends on what gearbox is bolted to the engine and what type of cat is it powering. Globally speaking, GM through their Opel division claims that the new engine will return at least 13% better fuel economy than the similarly-sized engine it will replace.
When the engine is introduced, the 1.6-liter will be found under the hood of several Vauxhall and Opel vehicles throughout Europe and it will be offered with different output of power. The range-topping variant will be able to produce at least 200 horsepower and 221 pound-feet of torque.
Opel/Vauxhall division also confirmed that the new 1.6-liter engine would be built in Szentgotthardt factory plant, Hungary. The production is set to start before the end of this year.
