Toyota has probably been able to recover a lot of their hybrid development costs by applying it to many platforms. They likely also are able to offer it for a lower cost on vehicles like the Prius and Camry by padding the price on high end Lexus vehicles. Nissan looks set to follow a similar strategy with Infiniti after their own system is available. This would allow Infiniti to continue offering higher-performance vehicles while cutting emissions and fuel consumption relative to similarly-powered gas-only versions. If they do offer hybrid Infiniti models it will be interesting to see how they compare to the upcoming diesels.
