Better engine crankcase breathing and efficiency.: Significant development work and computer - aided engineering optimized the cylinder block for more efficient airflow in the crankcase as the pistons move up and down in the bores, resulting in improved torque at higher engine speeds.

When cruising at medium to high speeds, the high - efficiency Atkinson - cycle i - VTEC gasoline engine provides propulsion via a high capacity lock - up clutch, which connects the generator motor (always linked to the engine) and the electric drive motor, effectively sending motive power directly from the engine to the drive wheels.

The CT6 Plug - In system is designed to provide responsive, all - electric driving for most daily commutes, while maximizing fuel efficiency by providing blended power from the engine and battery at higher speeds and higher loads.

The system switches to this mode for higher - speed driving when the gasoline engine operates at peak efficiency.

At all loads and engine speeds they strike an optimal balance between minimal friction and high thermodynamic efficiency.

Lift off the throttle at high speeds and the engine shuts down for better efficiency.

The engine is a twin - turbo V8, a not unusual configuration for sporty cars, but the 592 hp output is, and so is the efficiency, rated 22 mph on the highway and higher in real life, about 30 mpg at reasonable highway speeds.

With its two mono - scroll turbochargers, charge air cooler, High Precision Injection, VALVETRONIC variable valve timing and Double - VANOS fully variable camshaft timing, the six - cylinder in - line engine and takes a clear and consistent aim at the higher echelons of performance, but is equally committed to developing significant torque from low engine speeds and achieving high levels of efficiency (fuel consumption combined: 8.4 l / 100 km [33.6 mpg imp] *; CO2 emissions combined: 197 g / kmHigh Precision Injection, VALVETRONIC variable valve timing and Double - VANOS fully variable camshaft timing, the six - cylinder in - line engine and takes a clear and consistent aim at the higher echelons of performance, but is equally committed to developing significant torque from low engine speeds and achieving high levels of efficiency (fuel consumption combined: 8.4 l / 100 km [33.6 mpg imp] *; CO2 emissions combined: 197 g / kmhigh levels of efficiency (fuel consumption combined: 8.4 l / 100 km [33.6 mpg imp] *; CO2 emissions combined: 197 g / km *).

When cruising at medium to high speeds, the high - efficiency Atkinson - cycle i - VTEC gasoline engine provides propulsion via a new higher capacity lock - up clutch, which connects the generator motor (always linked to the engine) and the electric drive motor, effectively sending motive power directly from the engine to the drive wheels.

The effective - compression ratio is less than 9:1 at low - rpm speeds for good drivability and much higher at high engine speeds for increased efficiency and power.

Seventh and Eighth gear are longer ratios that accommodate lower engine revs and better efficiency at high road speeds.

This Ti - VCT engine, delivering at least 280 horsepower and E85 compatibility, is mated to a unique six - speed automatic transmission that combines lowered initial gears for improved off - the - line acceleration and higher gearing for improved efficiency at lower engine rpm when cruising.

Nissan Motor Co. says it has developed a new turbocharging system that provides improved torque and engine response at low speeds in city driving.Nissan says the new system will give a 2.5 - liter engine the same fuel efficiency as a 2.0 - liter engine and the same low - speed torque as a naturally aspirated 3.5 - liter engine.The new system will be introduced in new models for the Japanese market later this year.The system is based on what Nissan calls a «linear charge concept,» which allows boost pressure to rise gradually with acceleration, increasing on a linear level from low to high speeds.

Designed for high efficiency at every speed: The seventh gear is configured as a high - geared overdrive which reduces engine speed, thus cutting fuel consumption.

With it's high - efficiency 1.8 L, 4 cylinder engine, the Honda HR - V is easy on gas, achieving an enviable 25 MPG in the city and 34 MPG on the highway, while the RAV4's 2.5 L, 4 cylinder engine is rated at 24 MPG for city driving and 31 MPG at highway speeds.

Engines do not develop constant power at all speeds; they have specific speeds where torque (pulling power), horsepower (speed power) or fuel efficiency are at their highest levels.

Oversize engines designed to operate at low working loads with high efficiency, producing less engine noise and vibration at normal cruising speed.

For long high speed trips the engine would be at full power max efficiency with exhaust capable of heating solid oxide electrolyser cell producing h2 and O per electric and water.
