6-speed automatic transmission with an improved efficiency electric oil pump. To further improve fuel economy, all of the Theta II major driveline and cooling system components have been optimized to reduce friction, while the crankcase has been filled with low friction oil. Regenerative braking system. Integrated starter generator.

inches) and high compression ratio (14:1); multi-hole direct fuel injectors; a variable cooling system; cooled Exhaust Gas Recirculation (EGR) system; and a full variable oil pump. The PCU’s DC-DC converter—which converts a direct current from one voltage level to another—is optimized to reduce overall power consumption.

and has higher capacity than the nickel metal-hydride battery used in the first-gen model (310.8v A water-cooled oil cooler integrated with the air compressor helps to provide reliability. In the 2021 Mirai, a second DC/DC converter augments the main DC/DC converter to respond to the auxiliary load increase.

A new torque converter provides a wider range of lock-up operation (versus the outgoing 6-speed automatic transmission) to imbue a more enveloping and direct driving feel. The converter contributes to low fuel consumption and passenger comfort, since engine revving is kept to a minimum. inches; bore remains at 3.44

The world’s first V8 gasoline engine with two turbochargers and two catalytic converters in the V-section between the two rows of cylinders maintains its maximum output of 300 kW/407 hp from 5,500 – 6,400 rpm. V8 with TwinPower Turbo Technology. liter V8 was terms presented for the first time in the BMW X6 xDrive50i. kWh, with 1.4

This creates a high expansion ratio for less compression, reducing intake and exhaust energy losses and converting combustion energy to engine power more effectively. With the stiffer platform and lighter components, the shocks can use lighter-viscosity oil, so they move easily and respond to small inputs more quickly.
