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 First Drive Review | Entry-level luxury that wants to have fun

NASHVILLE, Tenn. — For 2019, the Lexus ES is all new and marks the seventh generation of the Japanese nameplate's entry-level luxury four-door. We're happy to report that the redesign brings some very welcome attributes, and the 2019 Lexus ES does everything you'd want an entry-level luxury vehicle to do. Performance, no matter which of the two drivetrain options you choose, is respectable, interior comfort is on par with a Restoration Hardware sofa you'd spend real money on, handling is communicative, and most important for a Lexus, it's serenely quiet inside. While these are great attributes, there are a few places we wish Lexus had spent more energy revamping. Through the humid hill country just outside Nashville, on a mix of the congested city arteries and the flowing switchbacks of Tennessee's forested interior, we put the ES through its paces. The 2019 ES is based on Toyota's TNGA platform, which underpins both the latest Avalon and Camry models. Perhaps that'd constitute a knock in a previous era, but the new Camry chassis is a rollicking peach compared to some others in its class. It's rigid enough for a windy road dance, but compliant enough for daily-driver duties. Even better, Lexus engineers improved the TNGA platform for use in the ES. A 200 percent increase in stiffness over the previous ES is due in part to a liberal use of structural adhesives and laser-welded screws. The front strut towers are reinforced, and topped with a brace between them. This extra attention to detail pays dividends that include a smoother ride and better handling. New adaptive Dynamic Control Shocks quietly smooth out bumps and undulations, allowing us to wind through the rural backcountry roads confidently, and the steering gives better feedback than we'd expect from a vehicle like the Lexus ES. Pushing the big sedan into one of the many hilly, and often blind, corners along our route elicits only a minute amount of body roll. But chassis improvements aren't the only upgrade from the previous model. The 2019 Lexus ES comes standard with a 3.6-liter V6 delivering 302 horsepower at 6,600 rpm and 267 pound-feet of torque at 4,700 rpm. This represents a bump of 34 hp and 19 lb-ft from the previous generation's V6. The engine is coupled to Lexus' new eight-speed automatic transmission, which is encased in a housing smaller than the brand's previous six-speed automatic.

Lexus LS mid-cycle refresh to restore V8-powered LS 600h hybrid?

When Lexus launched the fifth-generation LS at the end of 2017, the Japanese luxury maker predicted its once-brand-defining sedan would sell 12,000 units per year in the U.S., a threshold the model hadn't reached since 2010. The LS managed 9,301 transactions here in 2018, its first full year on sale, falling back to 5,528 units in 2019. Through the first three coronavirus-affected months of this year, Lexus dealers have sold 801 LS sedans, compared to 1,404 units in Q1 2019. There's a mid-cycle refresh supposedly due for release in the fall of 2021, and the June issue of Japanese magazine Mag-X (translated), via Lexus Enthusiast, claims we're due for a couple of big surprises that could jolt the sales figures. The first shock is that Lexus is supposedly bringing back the LS 600h moniker for an LS with a V8 hybrid powertrain.  Lexus debuted the LS 600h L in 2007 for the 2008 model year, retiring the hybrid trim in 2016. Its heart was a 5.0-liter naturally aspirated V8, and when combined with an electric motor, combined output came to 439 horsepower and 385 pound-feet of torque. The fifth generation introduced the LS 500h that switched to a naturally aspirated 3.5-liter V6, producing a combined 354 hp and 369 lb-ft., taking second place in output to the twin-turbo V6 in the non-hybrid LS 500 with 416 hp and 442 lb-ft. If Lexus were to double back to a V8 after experimenting with a V6 hybrid for four years, some question which V8 would get the nod. The old V8, codenamed 2UR-FSE and still in use in the Lexus LC as the 2UR-GSE, dates back 14 years and is scheduled to retire in two years when the LC-F introduces Lexus' new twin-turbo V8. According to leaked dealer information, that's the same year Toyota and Lexus will stop offering V8 engines in any model with an MSRP under $90,000. Toyota has shied away from turbocharged hybrids, but the next-generation Tundra could change that if rumors of the 3.5-liter twin-turbo V6 i-Force Max engine come true. A twin-turbo V8 LS hybrid would rocket the model back to the top of the range in performance and price, and we could see it breaking the "F" seal on the LS lineup, since it would run counter to everything the German competitors are doing with their standard flagship sedans. Or Lexus could remove the turbos for a better compromise of potency and frugality.
