Electric Turbocharger
An electric turbocharger has an electric motor on the turbo shaft that spins it up instantly, reducing lag before exhaust flow builds.
What is Electric Turbocharger?
It usually needs a 48-volt electrical system. A related idea is a separate electric compressor that boosts at low revs. The motor can also recover energy from the exhaust. Formula 1 power units have used electric assistance on the turbo shaft.
How it works
The motor accelerates the compressor wheel directly, so boost arrives before exhaust energy is high.
Why it matters for your car
It adds weight, cost and electrical complexity. Repairs require specialist knowledge.
