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.

2019 Mercedes-Benz G-Class vs big luxury off-roaders: How they compare on paper

During our first drive of the 2019 Mercedes-Benz G-Class, the all-new SUV's product manager was asked to identify competitors that might have been benchmarked in its development. The look on his face was about the same as if someone had asked him to recite King Lear in Klingon. As far as Andreas Hoeppel was concerned, the G 550 and AMG G 63 doesn't actually have a rival, or at least something the engineers and designers thought to compare it against. The G-Class is a G-Class, who cares what the other guys are doing? Well, in case you care, we figured we'd plug the new G-Class' specs into the old Autoblog Comparo Generator 3000 (TM) to see how the G 550 and AMG G 63 compare to the Range Rover and its mightiest SVAutobiography Dynamic model, plus the Lexus LX 570 and Bentley Bentayga V8. Frankly, Heir Hoeppel was onto something as each of these is wildly different. But, they do share some common elements: giant size and weight, ultra-lux interiors, and far more off-roading capability than other luxury SUVs offer and any of its owners are likely to ever utilize. Sad. So enjoy this trip down specification lane, and if you're still left hungry, you can always check out our Range Rover comparison or create your very own comparo. Off-Road Clearances and Capability All the fancy off-roading software and special cameras in the world won't do you a lick of good if your SUV is too close to the ground or has low-hanging body work that'll get easily ripped off. As such, check out each of these uber-SUV's ground clearance, approach and departure angles, and wading/fording depths. In this case, the Range Rover has an advantage due to its air suspension that can raise itself into an Off-Roading height that's a whopping 2 inches higher than the new G-Wagen. Sadly for itself, Lexus only provides figures for its air suspension when in normal height. It could match or surpass the Range Rover for all we know (but doubt it). As Land Rover does provide figures for the Range Rover's approach and departure angles in normal and Off-Road height, you can get an idea of just how much clearance the new G-Wagen has without any fancy (and expensive to fix) raising and lowering air suspension hardware. In fact, its departure angle is better than even the Range Rover's Off-Road height. Bentley doesn't provide any such information despite touting the Bentayga's surprising off-roading talents.

Lexus reportedly debuting a trio high-performance, V8-powered F models

The V8 engine may not be long for this world, but before it disappears forever Lexus may give it a proper sendoff with a trio of eight-cylinder F cars. If reports out of Japan are true, Lexus is working on high-performance F variants of the IS and LS sedans, as well as the LC flagship coupe. The story comes form Japan's Best Car magazine, which claims the Lexus IS F will soon be making a return. Based on the updated 2021 Lexus IS, it will run an up-tuned engine that puts out 474 horsepower and 395 pound-feet of torque. That's a 58-horse and 24-lb-ft increase from the last IS F. To be honest it would be a bit surprising to see an IS F at this point, as the previous, third-generation IS skipped an F version. And since the 2021 IS sedan is based on that same platform, it seems Lexus would have introduced an IS F successor much earlier if one was in the cards. As much as we would love to see the IS F return, we won't hold our breaths for this one. Still, an IS F would be nothing, shock-wise, compared to what comes next. Best Car says Lexus will introduce an LS F to go up against the Mercedes-AMG S 63 and BMW M760Li. Power would come from a new 4.0-liter twin-turbo V8 making 661 hp and 480 lb-ft of torque. If true, this would drastically counter the LS's mission of smooth luxury that's been its raison d'etre since 1989. Out of the three, the car that makes the most sense to us is the LC F. It's been rumored for quite a while. We even saw spy shots of the car testing in 2018, but then came chatter that the car was canceled due to the COVID-19 pandemic. According to Best Car, it's back on (or was never canceled) and will share a mill with the LS F. The report also says that all three cars have sport suspensions and chassis improvements that properly harness the power of these engines. Lexus has proven it can build compelling high-performance cars like the IS F and GS F, which were far better than what their sales numbers indicated. Furthermore, the Lexus V8s themselves are machines of engineering beauty, amazing throttle response and glorious sound. Naturally, we'd welcome any of these cars, even as we take the article with a massive grain of salt. Related Video:
