Bentley Bentayga Hybrid. A plug-in hybrid model was revealed at the 2018 Geneva Motor Show and went on sale in the UK, Europe, and North America in October 2019. It combines a 3.0 L V6 turbo petrol engine and an electric motor, for a system output of 449 PS (330 kW; 443 hp) and 700 N⋅m (516 lbf⋅ft) of torque.
Exhaust heat management is the means of lessening the damaging or performance-robbing effects of internal combustion engine exhaust heat by preventing heat from escaping from the exhaust system and into the engine compartment on automobiles.
Rolls-Royce acquired Bentley in 1931 and continued to use Bentley engines alongside their own for a time, although none was a V8. Prior to World War II , Rolls-Royce had developed a 7.3-litre V-12 for the Phantom III , which was succeeded by the inlet-over-exhaust B60 straight-6 and B80 straight-8 series of engines.

An exhaust heat recovery system turns waste heat energy in exhaust gases into electric energy for batteries or mechanical energy reintroduced on the crankshaft. The technology is of increasing interest as car and heavy-duty vehicle manufacturers continue to increase efficiency, saving fuel and reducing emissions.
A typical automotive cooling system comprises: a series of galleries cast into the engine block and cylinder head, surrounding the combustion chambers with circulating liquid to carry away heat; a radiator, consisting of many small tubes equipped with a honeycomb of fins to dissipate heat rapidly, that receives and cools hot liquid from the engine;
The electric motor is powered by a 240-cell, 288 V, 6 Ah nickel metal-hydride battery array. The 4motion four-wheel drive system utilises a lighter Torsen centre differential from the Audi Q7 to save weight. The electric motor has a top speed of 50 km/h (31 mph). Start-stop system supports regenerative braking, and coasting. Power steering and ...
