Supra: The 2014 Detroit auto show unveiling of the FT-1 concept points clearly to the direction Toyota wants with its Supra successor. Toyota and BMW are working together on sports car architecture that will spawn the next Supra, as well as a production Lexus LF-LC. Given that Toyota and BMW have a history of inline-six engines and are both heavily into turbocharging, expect the Supra to carry a turbocharged inline-six that generates at least 425 hp. This is intended to be a throwback rear-wheel-drive sports car -- no hybrid version, no all-wheel drive. Code-named Silk Road internally, the next-generation Supra should arrive in fall 2017 or spring 2018. Some insiders say it will not be called Supra, as the company has trademarked the nameplate "Mirai."
Prius: Toyota has delayed the start of production for the fourth-generation Prius from next spring until December 2015, as engineers sweat last-minute platform-sharing details. The car will debut the global architecture modular platform, as well as its next-generation hybrid system. The new hybrid system is expected to be smaller, lighter and more efficient. It will get a choice of a low-cost nickel-metal hydride battery as well as a lithium ion version for different usage cycles. Supercapacitors also are being tested for start-stop applications. The Prius also may get an awd layout in addition to its current front-wheel-drive one.
Prius C: Launched in spring 2012. It uses the Yaris platform, rather than that of the Prius, and there could be a next-generation model sold in the United States if there is demand for it.
Prius V: The tall wagon in the Prius family launched in summer 2011. A redesign will probably arrive in late 2017.
FCV: The small-volume hydrogen fuel cell vehicle will go on sale in fall 2015 in California. Toyota hopes to achieve a 300-mile range. Toyota says the hydrogen tank can be filled in three minutes. The price in Japan is the equivalent of about $68,000, but U.S. pricing hasn't yet been announced.
RAV4: Redesigned in spring 2013. A midcycle freshening in 2016 could include the adoption of the 2.0-liter turbo engine. However, because the turbo was developed with a different front subframe from the existing inline-four, the restructuring of the engine bay may prove too expensive, forcing the turbo to wait for a spring 2018 redesign off the TNGA platform.
Highlander: Redesigned in January.
Venza: It's a parts-bin car, so it's a cheap Camry derivative to build. But its relative lack of market success and marketing support has some wondering if the Venza will be a one-and-done project.
Sienna: Redesigned for the 2011 model year. A typical six-year cycle would mean it will come out at the same time as the next-generation Camry. But delays in the TNGA could push Sienna to a spring 2018 redesign -- an eight-year cycle -- but with a substantial midcycle update for the 2015 or 2016 model year.
FJ Cruiser: Its run ends this year.
4Runner: Redesigned for the 2010 model year. Toyota typically runs seven-year cycles for its truck-based products, so expect a 2017 model redesign, still borrowing from Hi-Lux/Land Cruiser Prado platform.
Sequoia: It's not selling well, and it carries a big corporate average fuel economy penalty. And if Highlander demand increases, that could crimp production at Toyota's Indiana plant. But Toyota is committed to a full lineup of body-on-frame SUVs, says Motoharu Araya, executive chief engineer for Toyota's global truck and SUV lines. If that's the case, a redesigned Sequoia would remain on the Tundra platform. And the cadence would indicate an early 2015 redesign. If it's coming, Toyota has done well hiding it.
Land Cruiser: It was the first nameplate Toyota sold in the United States, so eliminating it for slow sales would be a major loss of face. It also carries big margins, and it sells well in markets where the roads aren't as nice or don't exist at all. A redesign for the 2017 model year would be on cadence.
