For the most part, then, the new vehicle will make use of the same technology, though Toyota will apparently have to do some retro-fitting in order to make it work inside the current Lexus LS. (Unlike the LS, the Mirai was built from scratch as a hydrogen car.) If Motoring's report is correct, the new Lexus will have a fuel cell under the front seat, with the hydrogen tanks located behind the rear seat.
Also, despite the fact that the LS wasn't originally designed as a hydrogen vehicle, it will reportedly offer nearly the same range as Toyota's existing FCEV: 239 miles, versus 300 on the Mirai. No word yet on price or whether this report is even true. And we suspect it could be a while before anyone sets the record straight -- the hydrogen-fueled Lexus LS is rumored to launch "by 2017," up to two years from now.
