GS: A re-engineered version arrives in early 2012 on an updated platform shared with the IS. But it will retain the same wheelbase and width and will be barely longer overall. The suspension has been modified for a sportier ride.
Engine offerings still will include a 3.5-liter V-6, with a six-speed transmission, and the 4.6-liter V-8, but with faster acceleration and better fuel economy. A four-wheel steering system will be optional. Lexus is considering a GS-F performance edition but using hybrid power instead of a hulking V-8 to make it happen.
LS: A redesign is due in the spring of 2013 for the big flagship sedan. Weight-saving technology using premium materials is high on the priority list. As for the range-topping LS 600h, Lexus will place more emphasis on fuel economy than performance, but it will stick with a V-8 hybrid, not drop down to a V-6.
LFA: After the current batch of 500 is built, there likely will be a one-year hiatus before a roadster version is offered, probably in mid-2014.
RX: A redesign is planned for early 2014. The crossover currently rides on an ancient platform that will be updated with the new Toyota Camry/Avalon underpinnings. The hybrid battery may stay nickel-based, rather than use lithium ion, since Toyota has found packaging gains but only marginal fuel efficiency improvement from lithium.
GX: It was redesigned in the spring of 2010, so no major changes are expected.
LX: Since the incremental volume of the top-line SUV helps justify Toyota's investment in the Land Cruiser, the LX won't go away. But expect the current version to stick around longer than planned, perhaps beyond 2015.
VX: After years of study and several concept models, Lexus has delayed the idea of a seven-seat car-based crossover.
