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.

Toyota fears supplier pressure in Australia with GM pull out

With Ford and General Motors both announcing an end to production in Australia, the country's auto industry is in a bad way. With the exit of two big players, there's increased concern that a third Australian manufacturer, Toyota, will be forced out, as well.
"We are saddened to learn of GM Holden's decision. This will place unprecedented pressure on the local supplier network and our ability to build cars in Australia," Toyota Australia said in a statement. The GM closure of Holden production will be the direct end to 2,900 jobs, but will also force a dramatic reduction in the size of the country's supplier network, as there will simply be fewer cars to build.
In the same statement, Toyota Australia said it would work with suppliers and local government to figure out whether continuing production Down Under was even feasible. According to Automotive News, a representative for the Australian Manufacturing Workers' Union told reporters it was "highly likely" that Toyota would also close up shop within the next few years.

Lexus reportedly working on two different successors to the LFA

The successor to the Lexus LFA is beginning to take shape — in unofficial rumors, at least. The firm's next supercar will reportedly make its debut in the coming years with a V8 under the hood, and it will be followed by a battery-electric model due out at the turn of the decade. Citing anonymous inside sources, Japanese magazine Best Car wrote that the long-awaited car that will take the torch from the limited-edition LFA will land in showrooms in 2025. As we've previously reported, it will be powered by a gasoline-electric hybrid powertrain built around a mysterious 4.0-liter V8 engine fitted with two turbochargers. The publication adds that the coupe, whose name hasn't been confirmed, will be launched as a regular-production model and that it will be built on a version of Toyota's TNGA-L platform. This is the same architecture found under the LC and the LS, among models, and using these foundations should allow Lexus to keep the car's cost in check. Engineers could peg the hybrid system's total output at around 700 horsepower, and Best Car reports that the car's front end will borrow styling cues from the Electrified Sport concept (pictured) introduced in December 2021. If the report is accurate, sales will start in 2025. Speaking of which, the Electrified Sport will make its debut with a battery-electric powertrain in 2030 at the earliest. Its design will evolve over the next eight-plus years; it sounds like what we saw in December 2021 more accurately previewed the hybrid supercar than the electric one. It could hit 60 mph from a stop in under 2 seconds, and it could offer a maximum driving range of over 430 miles. Interestingly, the same report points out that the Electrified Sport might use solid-state batteries. That technology's not ready, but Lexus has plenty of time to fine-tune it. Toyota GR GT3 Concept View 8 Photos On the Toyota side of the family tree, the GR GT3 concept unveiled in January 2022 is allegedly on its way to production (in one form or another) as well. It will initially spawn a race car built to GT3 specifications, as its name implies, and it will benefit from the lessons that engineers learned while designing a road-going, Le Mans-inspired hypercar that Toyota consigned to the automotive attic in August 2021. Whether the GR GT3 will be related to the LFA's successor is up in the air, though it doesn't take a significant stretch of the imagination to speculate that some parts will be shared.
