Lexus seems to be very busy developing its new lineup, since the LS will be also replaced with a new model in 2013. The current model is a really good car, but it lacks character in my opinion. Well, this may be about to change judging by this rendering. So, BC claims that the all-new LS 600h, which will continue to be the top of the line version, will be powered by a 5.0L V8 engine delivering 400 ps and 55.0 kgm of torque. Oh, then we've got the electric motor! Fuel efficiency should be around 15.0 km/L, which doesn't seem a lot at first glance, but we are talking about a big car.
