As you'd expect, with the help
of an
electric motor and
turbochargers, the Turbo S E-Hybrid has a massive amount
of torque; the two motors endow it with 627 lb ft. With a boost strategy taken from the 918 Spyder — even though that was a naturally aspirated, lightweight hypercar — the S E-Hybrid generates its peak torque at 1400rpm.
One other potential product strategy could be for the production RX - Vision to arrive in 2020 with a new generation

electric turbochargers.
It included a 3.7 L V6 gasoline engine with twin
turbochargers rated 440 PS (320 kW; 430 hp), an
electric motor (called 3D Motor) rated 160 PS (120 kW; 160 hp) and 500 N ⋅ m (370 lb ⋅ ft), with a combined rating

The hybrid propulsion system (V6 1.6 turbo gasoline engine, two
electric engines driving the front axle, another one driving the rear axle — MGU - K, and one more, called MGU - H, virtually driving the
turbocharger electrically so no need to rely on excess exhaust gases as until now) from Formula 1 provide a fascinating combination
of performance and efficiency.
At more sedate speed, though, the i8 makes a more convincing argument for hybrid performance, especially in 80 to 120 km / h «passing» acceleration where the combination
of torquey
turbocharger, equally torquey
electric motor and slick - shifting six - speed automatic transmission give it jump to make even supercars jealous.
But compared to the previous E-tron concept, this one is powered by a
turbochargers 3,0 Liter TDI engine with an output
of 300 HP, combined with two asynchronous
electric motors with a total output
of 88 HP.
The system also allows the installation
of an innovative
electric supercharger for the CRDi engine, in addition to the conventional
turbocharger, which helps to boost torque and engine response at low engine speeds.
Unique here is the method
of «twin» - turbocharging deployed — there's only one exhaust gas
turbocharger, but it's helped by an
electric auxiliary compressor.
Finally, an auxiliary
electric coolant pump is programmed to run after the engine is shut off to prevent overheating
of the
turbocharger bearings.
Electric vehicles are more cost - effective to develop, and branching out into high - performance variants won't require the same level
of time and effort (or extra
turbochargers and reciprocating parts) as high - output petrol engines.
That's where the
electric motor comes in — think
of its as sort
of a substitute for a
turbocharger that instead
of cramming more fuel in, effectively reduces fuel requirements, while still yielding more total power.
The system also allows the installation
of an innovative
electric supercharger for the CRDi engine, in addition to the conventional
turbocharger, providing improved power and torque at all engine speeds.
The thermal efficiency
of the combustion engine with
electric turbocharger (MGU - H) in conjunction with the
electric motor on the crankshaft (MGU - K) will be more than 40 %.
The
electric powered compressor supports the
turbochargers at times when the exhaust gas is insufficient for rapid development
of power.
For the first time, the
turbocharger of the internal combustion engine is linked to an electrical machine, which makes it possible to convert the thermal energy
of the exhaust gas flow into
electric energy — for instance, when the boost pressure limit has been reached.
Its technical refinements are the exhaust manifold integrated into the cylinder head, the rotary - valve model for thermal management, the Audi valve - lift system (AVS) for the outlet valves, the
electric wastegate
of the
turbocharger and the dual fuel injection.
First and foremost, its features a revolutionary
electric powered compressor (EPC) that forces air through mechanical
turbochargers when the engine is in the lower reaches
of the rev range, purportedly doing away with traditional turbo lag by reducing the spool - up time.
Although using the same 3.5 - liter V6 with combination direct and port injection, it drops the twin
turbochargers in favor
of its complementary
electric drive system, making for a total output
of 354 horsepower.
The twin - scroll
turbocharger integrated into the steel exhaust manifold and
electric wastegate control is extremely efficient — on account
of its compact construction and the presence
of an indirect intercooler integrated into the intake manifold.
The engine will power the rear wheels with the help
of an
electric motor while a second rear mounted
electric motor will help power the
turbocharger itself.
Actually, strike that, because two
of the
turbochargers will be powered by electricity, not exhaust gases, therefore the term «
electric turbochargers» should be better - suited.
At the heart
of the Bentayga diesel is a new 4.0 - liter V8 that uses two
turbochargers and an
electric supercharger.
That electrical technology also spreads to the
