Solutions for lag on big turbos perhaps?

I thought I'd post this up because I thought it was an interesting way that Volvo has implemented the charged and turbo set up.
450hp from a 2ltr engine is quite amazing considering that it's dead stock and you have factory warranty!
Imagine having a compact pre-turbo electric charger to help in off/low boost driving

I wonder if future Evo's will have a similar system.

The future is in electric power boosters and energy recovery systems..........I can foresee highly efficient capacitors being an integral part this.

I have a few ideas.....................................

No more Evos man...final edition Evo 10 is the end of them unfortunately

Careful with those new ideas around here. Its a bit conservative.

That's a shame, what are they going to use for their next rally car?


I think Volvo's concept is a good idea, although it's been used in production cars before but with a belt driven S/charger rather than electric powered. Having an electric motor for the rear axle is a nice inclusion too.

I have been fascinated by how the F1 cars recovery systems work and can see a market for retro-fitting to older vehicles to assist from a standing start and at over 80% throttle. It's a trade off between power added and weight of batteries, but that's where the technology of capacitors would come in.

Imagine having an extra xxxTQ to boost off the line performance to get out of the hole till the turbo kicks in hard.

Volvo's system is great, conceptually at least. But still has too much lag, probably as a result of the massive boost it runs.
Audi and Saab had driveable concept cars with similar set ups over the last 5 years or so. Obviously these went nowhere unfortunately.
I think what Maclaren does with their P1 is the way to go. Having the electric torque from 0rpm and having the turbos take over on boost is a great idea... One day it will be adopted successfully in more mainstream cars, hopefully...

Let's hope so, but in the meantime we'll have to make do with this..............go to 6:15
