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.

2018 Autoblog Technology of the Year finalists

After months of prepping and several days of testing, we narrowed the field for Autoblog's 2018 Tech of the Year award to the Nissan Rogue with ProPilot Assist semi-autonomous driving system, the Lexus LC 500h and its new hybrid powertrain, and the Chevy Colorado ZR2 and its trick Multimatic spool-valve off-road shocks. Three very different cars with very different technologies duking it out for the award. Look for news of our winner at the 2018 Detroit Auto Show. We hand out this award every year to the technology or feature that we feel moves the bar forward for the automotive industry. Read more here on how our testing process works. We discuss, debate and count up score sheets, judging each vehicle and technology on a few different criteria. Is its purpose noteworthy? Does it work well? Does it advance the industry? The Nissan Rogue with ProPilot Assist was actually a prototype, as the technology will first debut in the 2018 Nissan Leaf. Still, we're here to test the tech and not the car. ProPilot Assist combines adaptive cruise control system combined with lane-keeping assistance. The system uses sonar, radar and a number of cameras for some light semi-autonomous driving and enhanced safety. While these systems aren't new individually, Nissan's system is affordable, intuitive, and coming to a mainstream product — democratizing the tech in a novel way, if you will. That's why it's here. The Lexus LC 500h uses a new powertrain that Lexus has dubbed the Multi-Stage Hybrid System. Basically it combines two types of transmissions — a CVT and a four-speed automatic — in a single unit mated to a naturally aspirated V6. That's complex and unorthodox technology, and Lexus engineered it to give drivers the efficiency of a CVT without sacrificing driving enjoyment. The package is subtle, working in the background to create a nearly seamless driving experience. It's engaging in a way most other hybrids can only dream of. The fact that it's wrapped in such gorgeous sheetmetal only makes things better. The Multimatic spool valve shocks in the Chevy Colorado ZR2 might seem low-tech compared to ProPilot Assist and the Lexus Multi-Stage Hybrid, but they represent a completely novel application of a technology that several years ago was so expensive that it was reserved for top-tier race cars. Like the LC 500h, these shocks really change your perception of how a vehicle like this should drive.

Best luxury SUVs of 2022 and 2023

Once upon a time, the idea of a luxury SUV meant a Range Rover, and even that was pretty agricultural by modern standards. Then Jeep Grand Cherokees and Ford Explorers started offering fancy, range-topping versions followed soon by Lexus, BMW and Mercedes dipping their toes in the water. And then the floodgates opened. Today, there is a staggering number of luxury SUVs available in every shape, size and price point. There are electric luxury SUVs like the Tesla Model X and Jaguar I-Pace, as well as gas-swilling, high-performance SUVs like the BMW X5 M and Cadillac Escalade V. Sports car makers Porsche, Aston Martin and Lamborghini have even dived in.  But of this great many, which are the best luxury SUVs? We sat down, scoured our reviews, took some votes, had some discussions and came up with the luxury SUVs we view as the best. They are listed alphabetically within the six segments listed below.  Best Subcompact Luxury SUV   |   Best Compact Luxury SUV   |   Best Midsize Luxury SUV (Two-Row) Best Midsize Luxury SUV (Three-Row)   |   Best Flagship Luxury SUV (Two-Row)   |   Best Flagship Luxury SUV (Three-Row)  Best subcompact luxury SUVs Mercedes-Benz GLB-Class Why it stands out: Outstanding space and versatility; legit luxury interior; amusing GLB 35 versionCould be better: Overwhelming and confusing tech interface Most subcompact luxury SUVs are a dubious value, with cramped interiors of marginal quality and unrefined driving dynamics. You'd be much better off paying less money for a loaded, non-luxury compact SUV. The Mercedes GLB is different, though. Its boxy design provides space few other subcompact SUV can match (luxury or otherwise), while its cabin design and feature content are in keeping with pricier Mercedes models. The quality's not exactly up to GLC standards, nor is driving refinement, but the difference is appropriate for how much you're saving and still perfectly acceptable. There's nothing dubious about buying a GLB.     Volvo XC40 Why it stands out: More features for the money; spacious and versatile interior; distinctive design; electric versionCould be better: Fuel-efficient base engine only available with FWD Most subcompact luxury models feel a bit like cheap knockoffs of their bigger, pricier brand mates. The XC40, by contrast, is a break from the Volvo norm in a good way.
