New Audiences PHEVs-Q5, A6,A7,A8

scooby77

So Audi getting into plug in hybrid games. Details in article below. 2.0 or 3.0 quattro tfsi engines with 14.1 kw battery. Dubbed tfsi e. I'm sure price be out of my league, but 3.0 357 bhp sounds like great fun!

14 Kwh is better than a lot of phev but why not go with a BMW i3 Rex like system where the car is driven 100% by the electric motor and the engine kicks in only when needed and never drives the wheels and use a much larger battery ?

357 Hp is easily achievable with a much smaller much simpler and much more efficient electric motor.

They could have done a lot better but too desperate they are to cling on to the ICE for as long as possible !

Would be the best situation alright

Probably need

50kWh battery and 1.5ltr petrol generator to match even your i3 rex range/performance

Mazda are going down this route, which I think is a great idea

30-40kWh battery and small high performance rotary range extender generator are the rumours for Mazda 3 EV/new CUV they have

Didn’t BMW abandon the Rex? Can’t think of any other car manufacturer doing a similar system either now so that’s tells me that there must be major flaws with it

Plug in hybrid and full EV is the future, all cars will be one or the other in the future

Generator needs to be very compact and powerful to keep up a charge at higher speeds

Rex in i3 is grand but not suited to larger cars

Its too weak, 25kW or something

Mazda are the only ones I know working on them

They have a compact rotary that can deliver up to 70kW at a similar size to Rex used in i3, but rotary doesn't have a good reputation for reliability and maintenance

Something like Nissan e Power scaled up would be my favourite

I love the electric drivetrain, but don't rate batteries as an energy souce

BMW only cancelled the Rex for the E.U , it's still in production in the 120 Ah in the U.S and probably else where.

Chances are the reason to cancel the Rex it was down to tax reasons, carbon credits and the likes.

BMW of course say it's down to the fact more people are buying the BEV than Rex in Europe. But that's silly, it will cost nothing extra to fill that gaping hole left where the Rex would sit.

They can make more powerful engines, and easily fit turbo charged engines, the idea is the engine is to get you home or it can be turned on on the motorway to keep the battery topped up like the rex before it runs down.

Agree with you totally

Think they are a fabulous

Give me a Leaf size 40kWh Rex over a 70kWh BEV any day

Petrol is the ultimate energy source, happy to use a small bit when needed

I'd take a 40 Kwh over 70 Kwh if I could charge it at 100 Kw that would make a big difference and of course if the network was much better.

Probably be fine coupled to a decent sized battery. It would barely ever be used so no apex tip wear to worry about
