Powered by the choice of two new engines mated to the nine-speed, the Cherokee features expected highway fuel economy ratings of up to 31 mpg US (7.6 The electro-hydraulic fully variable valve-lift system uses a column of oil in place of the traditional mechanical link between the camshaft and intake valves.

l/100 km) and 30 mpg (7.9 Increased efficiency in all of the new Ecotec engines is achieved in part through lower engine friction, which was reduced by up to 16% using new technologies such as a variable-displacement oil pump. Additional engine features include: A precision sand-cast engine block with cast-in-place iron liners.

GM says the ATS will be able to deliver peak highway fuel economy of more than 30 mpg. Increased efficiency in the new four-cylinders was achieved partly through lower engine friction, which was reduced by up to 16% using new technologies such as a variable-displacement oil pump and, with the 2.5L, an actively controlled thermostat.

l/100 km [147 – 157 mpg US] in the WLTP cycle; combined electric power consumption of 30.1 – 28.9 liter unit features a cross-bank exhaust manifold and an optimized oil separation process. Drivers can also select 4WD Sand mode, which has been conceived specifically for driving over dunes and similar surfaces.

Fuel efficiency is also improved for this higher-torque engine with an EPA-estimate of up to 25 MPG combined. Mud & Sand mode works well for beach driving, while Rock & Dirt mode optimizes AWD traction for trails. This results in a significant 17% increase over the previous 3.5-liter liter V6 engine’s 263 lb-ft (357 N·m).

l/100 km (32 mpg US)—7.2 l/100 km (33 mpg US) for 3-door—and 194 g/km (190 g/km for 3-door) respectively. The efficiency of the intake and exhaust ports, and the fuel injection system, has been optimized to maximise torque. It will accelerate from 0-100 km/h in 12.7 seconds, and on to a top speed of 175 km/h.

That’s because coal-fired and nuclear power plants that use steam to drive a turbine typically use water—vast amounts of water—to cool and condense the steam at the exhaust." At that rate of consumption and at an average of 20 MPG, the amount of water per electric gallon of gas is about 1.25 million gallons per day.
