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 develops new pre-collision system with steering assist

A number of automakers are working on developing fully autonomous cars, but it looks like the groundwork for such technologies will likely show up first as semi-autonomous systems for both safety and convenience. Following recent announcements from Nissan and Ford in this area, Toyota has now released information for some of its advanced semi-autonomous technologies that could be offered in production cars over the next few years.
On the safety front, Toyota's new pre-collision system with pedestrian-avoidance steering assist is aimed at protecting the folks who aren't in the car. This system combines visual and audible alerts with automatic brake assist and automatic steering. If warnings don't get the driver to slow down, the brake assist kicks in if a collision is very likely, but if that is still not able to avoid the impending collision (and if there is enough room to do so), the car can automatically steer itself around the pedestrian. This sounds most beneficial for last-second dangers such as a person accidently stepping out into the road in front of a car. Toyota hopes to have this technology available to customers by 2015.
The Japanese automaker is also testing a suite of technologies called Automated Highway Driving Assist (AHDA). The key part of this is a new adaptive cruise control system that uses vehicle-to-vehicle (V2V) communications rather than a radar-based system. This cooperative-adaptive cruise control allows vehicles to communicate their acceleration and deceleration data with other cars, which Toyota says this helps to improve fuel efficiency and traffic flow. Also a part of AHDA is the Lane Trace Control feature, which sounds like a next-gen lane keep assist. This system uses cameras, radar and a computer to keep the vehicle in a "smooth driving line" by being able to change steering angle, engine torque and braking force. Toyota says this technology could be in place by the "mid-2010s."

Why the Lexus GS death rumors aren't surprising

For months, rumors have persisted that the Lexus GS is dying, to be replaced in the lineup by the ever-growing ES. After spending some time with one, we can't really figure out why it hasn't happened sooner. For a long time, the smaller, less expensive, more efficient front-wheel-drive Lexus ES has been growing in size and dominating the rear-wheel-drive GS in sales. As customers move from sedans into crossovers, Lexus' five-car lineup of the CT, IS, ES, GS, and LS is looking a bit too crowded. We shouldn't lament the loss of another rear-wheel-drive sedan. Lexus customers sure as hell haven't. There are better options available. Outside of the GS F, the Lexus GS isn't a car that encourages you to drive in a way that would take advantage of a rear-wheel setup. In the rain and the snow, the front-wheel drive ES is likely to be a more stable and sure-footed car. If you want power, the less expensive ES 350 actually has a more powerful engine than the base GS 200t. It's nearly a second quicker to 60 mph as well. Stepping up to a GS 350 puts a nearly $12,000 divide between the ES and the GS. Yes, you can get the GS with all-wheel drive, but how many people well and truly need it? Size-wise, the ES is nearly identical to the GS, with the ES being longer but narrower by just over an inch in either direction. Being front-wheel drive, the ES has better rear packaging, meaning a roomier rear seat. The GS does beat the ES on cargo capacity, but on nearly every other measurement the ES is roughly identical or better. Another editor noticed the exact same thing when the current ES debuted nearly four years ago. That goes for pre- and post-refresh models. The ES isn't quite as handsome as the GS (as long as you ignore the spindle situation up front). From some angles, the ES looks like nothing more than the tarted up Toyota Avalon it is. From behind the wheel, the GS fails to convey any sense of excitement or occasion. It's simply a shoulder shrug of a car. When competition like the BMW 5 Series or Mercedes-Benz E-Class offer both refinement and a decent infusion of fun, it's hard to make a case for the Lexus. The ES isn't any better, but with a base price of $39,895 it's a far more reasonable proposition than a $47,305 GS. Our test car was starting to show its age, as the competition has long sailed by when it comes to noise, vibration, and harshness. Lexus quiet this GS 200t was not. All that said, it seems that customers have already spoken.
