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."

2019 Lexus ES 350 starts at just $550 more than outgoing model

Lexus wants you to pay attention to the 2019 ES. The all-new, seventh-generation midsize sedan that Lexus benchmarked against the Mercedes-Benz E-Class and Audi A6 gets a base price that just a few hundred over the old car. The entry-level ES 350 starts at $39,500; after $1,025 for destination and handling, that's $40,525 out the door and $550 more Washingtons than the 2018 model required. The mid-level ES 300h starts at $43,310, or $44,335 out the door. That saves $510 compared to the 2018 version, and it gets better fuel economy. The all-new ES 350 F Sport starts at $44,035, for $45,060 out the door. Every model rides on the Toyota New Global Architecture, known as GA-K here. The lighter, stiffer body hides improved mechanicals like rack-mounted electric power steering, and a new multilink rear suspension that encouraged fun driving during our recent review. The updated Lexus Safety System+ 2.0 comes standard on all models, and incorporates new features like daytime bicyclist detection and low light pedestrian detection. The ES 350 and ES 350 F Sport get a 3.5-liter V6 with 302 horsepower and 267 pound-feet of torque, 34 hp and 19 lb-ft over the former sedan, working through a new eight-speed transmission. The F trim makes itself known with 19-inch wheels, rear spoiler, and retuned suspension. EPA ratings for the ES 350 come in at 22 mpg city, 33 mpg highway and 26 mpg combined, an increase of two more miles per gallon on the combined cycle. The ES 350 F Sport is rated at 22 mpg city, 31 mpg highway and 25 mpg combined. The ES 350h uses a 2.5-liter Atkinson-cycle four-cylinder with fourth-generation Hybrid Drive. The 215 total horsepower from the ICE and electric motor returns 43 mpg city, 45 mpg highway, and 44 mpg combined. Lexus says this makes it the most frugal luxury car out there that doesn't have a plug. The ES is also the first Lexus to offer Apple CarPlay, on top of being able to use Amazon Alexa to communicate between the sedan and the home. The 2019 Lexus ES goes on sale in September.

2018 Lexus LS First Drive | Luxury, performance and the puzzling parts

When one imagines the enormous executive sedan that might be driven by a wealthy lawyer or banker (or their chauffeur), the mind naturally goes to the Mercedes S-Class or the BMW 7-Series. Venerable, enormous and expensive. But for those wanting to keep their driveway a little more understated, we also have the Lexus LS. Sure, it's not as ostentatious as the big saloons from Munich and Stuttgart, but it has a dignified elegance all its own. For nearly three decades, the LS has been a discrete and dependable Japanese luxury sedan. The new 2018 LS, perhaps thankfully, is a bit less discrete. We saw the new-look LS when it was introduced earlier this year in Detroit. Now we know how it drives. We put the 2018 LS through its paces on the traffic-clogged streets of San Francisco and over the Golden Gate Bridge to the twisty B-roads around Marin County and the legendary Skywalker Ranch, where we stopped for lunch. Unfortunately, all in attendance were sworn to secrecy about the details of Skywalker Ranch, but we're free to tell you all about the LS. Here's our one-sentence summary, which can be used to describe many cars to bear the Lexus badge: It's excellent in many respects, odd in a few, and incredibly, massively frustrating in one very important area. Lexus has a brand new 3.5-liter twin-turbocharged V6 paired with a 10-speed automatic transmission, a first for a premium passenger car. It produces 416 horsepower and 442 pound-feet of torque, up from 386 hp and 367 lb-ft from the outgoing naturally aspirated 4.6-liter V8. Lexus engineers are extremely proud of the fuel efficiency of the new engine, which required some clever technical innovations (a longer bore stroke and increased valve angle) as well as tech borrowed from Formula One, including a "laser clad valve seat" that allows for a more direct flow of air into the combustion chamber and a high "tumble ratio." In other words, Lexus figured out how to get more bang out of each gasoline-powered buck. Fuel economy numbers are 19 city, 29 highway, and 23 combined for the RWD version and 18/27/21 for AWD, with the highway numbers particularly helped along by the 10-speed gearbox. It's a torque converter unit, but Lexus promises shift times that rival its dual-clutch-wielding competitors. The LS is no slouch, either. In RWD trim, the nearly 5,000-pound car hustles from 0-60 mph in 4.6 seconds, according to Lexus' reckoning.
