Toyota announces new, more efficient powertrains for 60 percent of its vehicles by 2021

In the face of increasingly strict standards on fuel economy and CO2 emissions, Toyota announced today that it's introducing a new hybrid system, a new 2.5-liter direct-injection inline four-cylinder engine, and two new transmissions – an eight- and a 10-speed. The development of all of these components will be based around the Toyota New Global Architecture, or TNGA. Development of the systems has moved forward and the new powertrains will find their way into vehicles starting next year. TNGA, like Mazda's Skyactiv technology, is a complete design philosophy that focuses on more than just a clean or efficient engine. The first vehicle to deploy the TNGA platform was the current, fourth-generation Prius. With TNGA, Toyota focused on improving handling, ride, and braking performance. The new powertrains are meant to compliment this new platform by being both engaging to drive and fuel efficient. Since TNGA can be adapted for front-, rear-, or all-wheel-drive layouts, it's capable of underpinning a number of potential products. Toyota is arguably the leader in hybrid technology, and taking lessons learned in the development of the current Prius, the automaker has developed the new Toyota Hybrid System II, or THS-II, for rear-wheel-drive applications. Performance has improved versus the outgoing model, and Toyota says efficiency, especially at high speeds, has been improved. In addition, the system's use in plug-in vehicles has been improved. For the first time, the electric motor will be able to provide direct driving power, whereas before it simply acted as a generator. The new, naturally aspirated 2.5-liter four-cylinder, like the THS-II, has been designed around the TNGA platform. Most notably, the thermal efficiency of the engine has been improved. This means a higher output and improved exhaust and cooling. The new engine, which works in both traditional and hybrid applications, will proliferate through the Toyota and Lexus lineup. Toyota's two new automatic transmissions, like the new engines, are based on the TNGA system. That means a lighter and more compact design relative to similar transmissions. The 10-speed is intended for rear-wheel-drive Lexus products like the GS and LS. The tuning has been adjusted to improve response and smooth out shifts, though it's impossible to say how much it's been improved without getting behind the wheel.

Lexus IS builds, new F performance structure get SEMA reveal

Lexus just announced a new F brand strategy at SEMA, and while the products themselves are not getting a massive overhaul yet, it’s vital to understand the new terms if you plan on being in the market for a sporty Lexus soon. Prior to today, we had F Sport, F Sport Performance and F. The F Sport cars were mostly aesthetic upgrades, and while some of them had performance upgrades, not all of them did. Only one F Sport Performance vehicle exists now, and itÂ’s the IS 500 F Sport Performance. Meanwhile, we have a number of F models, which is LexusÂ’ highest-performance moniker.  Going forward, there will be four performance tiers: F SPORT Design, F SPORT Handling, F SPORT Performance and F. WeÂ’ll lay out LexusÂ’ definitions of all four below for you. F SPORT Design: These vehicles may feature sport-inspired exterior design, including unique front and rear bumpers, grille and wheels. F SPORT Handling: Will build on Design with sport-tuned suspension components honed at the track, including Adaptive Variable Suspension. F SPORT Performance: In addition to the updated suspension components, these models may receive a higher-performance powertrain, as seen in the 2022 IS 500. F: As the highest expression of Lexus performance, F models will be further upgraded with innovative components developed for the racetrack, including upgraded brakes, advanced aerodynamics and lightweight materials. So there you have it. Similar to the Germans with multiple layers of AMG, Audi Sport and BMW M, Lexus will have multiple layers of F. In addition to this actual product news, Lexus revealed a pair of SEMA show cars. Both of them are from the IS tree, with one being an IS 500 F Sport Performance, and the other being an IS 350 F Sport. WeÂ’ll start with the IS 500. Hiraku & Townsend Bell is behind this “Street Performance” IS 500. Nothing much changed with the powertrain, but it does add an AÂ’Pexi induction box, TOMS Racing carbon fiber suction pipe and AÂ’Pexi exhaust system. Handling is enhanced with TOMS chassis braces in the front and rear. Plus, it gets an AÂ’Pexi adjustable coilover system. Rotiform LAS-R 20-inch wheels are wrapped in Nitto tires, and a Brembo GT braking system improves stopping power.  You can tell that the IS 500Â’s appearance has been modified, too — itÂ’s sporting a one-off 3-D-printed body kit.

Lexus planning a hydrogen fuel-cell LS by 2017

Toyota's Fuel Cell System will certainly migrate to other vehicles in the carmaker's lineup, but Australian car site Motoring reports that one of the models at the head of the queue is the Lexus LS. According to its sources, the executive barge powered by hydrogen will be released by 2017 and take the top spot in the range, rolling in above the LS Hybrid. We're told that Toyota engineers will find a way to slide two hydrogen tanks into its bodywork with the same general setup as on the Mirai – one under the rear seats and another under the rear parcel shelf. The 150-kW fuel cell stack will be placed under the front seats. Motoring says the resulting sedan and its 220-kW electric motor would come in "at around 2,100 kg," which is 4,620 pounds; that's a ginormous 539 pounds less than the listed curb weight of the current LS Hybrid, and 387 pounds more than the standard LS. Assuming all goes as planned, it would have a range of roughly 238 miles, a few dozens less than the Mirai's range of about 300 miles. It would look slightly different, too, the front end getting larger intakes to cool the power unit. It wouldn't surprise us if Lexus does have a hydrogen LS planned – it would be a statement car, and the company likes making statements, even if few heed them; it has stuck with its LS 600h for the past seven years, yet of the 7,539 LS models sold through the end of November this year, only 61 of them were hybrids. The timing would be intriguing, however; by the time the LS hybrid came out, Lexus had already worked over its filet-and-potatoes models. And if the hydrogen version is going to come in above the $120,440 hybrid, well, that will be a statement indeed.
