Audi A6 now have Electric Biturbo

It's astonishing to think how far diesel engines have moved on in the last 20 years, but Audi is proving there’s a still lot more to come. Under the bonnet of this example A6 saloon is a new diesel engine based on the familiar 3.0-litre V6 Bi-turbo that uses an electric turbocharger in a bid to eradicate lag in total. Normally in the Bi-turbo, fatigue gases are used to reel up a small turbo which fills the breach in torque that comes at low revs when you base the throttle. 

 When adequate fatigue gases are imminent from the engine, a superior turbo kicks in. It’s effectual to a point, but this new set-up is a far improved proposal. Instead of relying on fatigue gases, the smaller turbo here is electrically driven and will previously be coil up from a standstill and at short speeds. The consequence, as we found out, is neck-snapping hastening off the line. 

Audi A6 Electric Bi-Turbo

The normal A6 Biturbo covers 0-62mph in 5.1 seconds, and while Audi couldn’t give us a precise time, engineers did tell us the electric turbo description were two car lengths in advance after just three seconds. The swap over between the electric and customary turbo is almost seamless, with only an insignificant dip in hastening that should be ironed out when this engine reaches construction. 

Engineers need to work on creation it more fuel competent, too as it stands it’s thirstier than the customary Bi-turbo. Audi couldn’t tell us when this engine will grace a manufacture car, but the technology doesn’t appear too far away. We’d bet on it being obtainable as a top-spec alternative in the next-generation A4. And with immediate responses, a growling engine note and scorching hastening, a diesel sports car is approximately certainly in Audi’s expectations.
