Furthermore, the front end was completely stripped of any superfluous sheet metal, and was clad in a composite one-piece clamshell to reduce weight and increase rigidity. The changes were complemented by lighter multi-spoke BBS wheels, and an evolved aerodynamics package, which further distanced the car from the production model. Meanwhile, Cosworth managed to extract some more revs (up to 12,800) to fire 457 horsepower at all four wheels.
The Opel Karl is powered by a new 1.0-liter turbocharged Ecotec three-cylinder making 74 hp, a bit less than the outgoing Chevrolet Spark’s 84 hp from a 1.2-liter four-cylinder. The three-cylinder engine is part of GM’s new global, small-displacement Ecotec engine family, so it’s possible that Chevrolet may offer a slightly larger turbocharged engine for the Spark in the U.S. The European-market Opel is also available only with a five-speed manual, while the Spark will almost surely be offered with an automatic transmission option.
Power will come exclusively from a three-cylinder 1.0-liter naturally aspirated gasoline engine developing 75 HP (55 kW) delivered to the front wheels through a five-speed manual gearbox. Opel and Vauxhall say the chassis has been tweaked to provide "exceptional safety and comfort" and both cars come with traction control, hill start assist and electronic stability control.
While the Ipanema clearly succeeded the Marajó, production of the Chevette (by now in sedan form only, the hatchback having been discontinued after the 1987 model year) and of the Kadett noticeably overlapped; the newer model was placed above the old one in Chevrolet's lineup. While Chevrolet entertained the possibility of a pick-up version of the Kadett E, it never materialized.
