Lexus ready hybrid supercar
Hybrid power looks likely for LF-A
The world’s first hybrid supercar is almost upon us, and may be shown at October's Tokyo motor show. According to an Autocar report, the news leaked out on the European launch of the LS600h saloon, when a senior executive revealed that “our plan is for every Lexus model to have a hybrid version”.
The forthcoming supercar – already previewed in two concepts badged ‘LF-A’ – is expected to feature a variant of the LS600H’s V8-based hybrid power train. In the LS it combines a 5.0 litre V8 and two electric motors to make 430bhp.
However, this is a luxury-biased motor, and it’s not too hard to imagine it being tuned to put out at least 500bhp, putting it in line with the proposed V10 engined version of the car.
Hybrid power is also being studied by Honda for their forthcoming NSX replacement.
Discussion
Hmm I don't mind Lexus hyrbids, namely because they don't look like them. They just look like ordinary cars. There not there to show off that you care about the environment, I'd consider one because of the technology. LS460h, GS450h, RX400h? Slightly less informed than the prius set I think.

Any bets as to whether this will come in under 2 tons?
Well the V10 car was supposed to be 1100kg, so how much extra does a hybrid RX weigh over it's petrol counterpart?
Yes, I'd be interested to know that too. I guess you'll get a marginal saving by having a V8 instead of V10, maybe 20-50kg? Then add all the electric motors, batteries, etc. I would make a wild guess it will be at least 200kg heavier as a result of the hybridism.

Peak power generated at different speeds presumably. I think the electric motors are usually geared so they provide most of their shove at low revs and so are starting to give up by peak engine revs.
Electric motors will generally have a flat power curve above a certain rpm, torque drops of with respect to rpm. Obviously depends on the motors used. And how they are used on the vehicle.
e.g. they only operate within a certain rpm/speed and are off above that.
