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."

Lexus ROV concept is a hydrogen-powered luxury side-by-side

Side-by-sides come in all shapes and sizes, but we've never seen one like the Lexus ROV concept. For one, it's a Lexus; the firm is not a big player in the side-by-side segment. It's as luxurious as the badge on its nose suggests, and it's powered by a hydrogen-burning engine. Lexus explained that the ROV (an acronym that stands for Recreational Off-highway Vehicle) is its "response to the growing passion for the outdoors and adventurous spirit of luxury consumers." It also illustrates the brand's wish to design lifestyle-oriented products, and it showcases the engineering department's research into new technologies. The ROV stretches 322 inches long, 68 inches wide and 71 inches wide. And, while it doesn't wear a giant spindle grille, it falls in line with the Lexus design language thanks to angular body panels. Inside, the ROV offers a pair of seats with harnesses and suspension elements to filter out bumps, carbon fiber accents and a relatively simple instrument cluster with an analog tachometer and a digital display. Lexus notes that the "Tazuna" approach to interior design that has shaped most of its recent concept cars permeated the ROV, meaning the cabin is human-centric. Interestingly, it also points out that the ROV meets the same quietness, durability, and reliability standards as the regular-production cars it sells, which is no small feat. Power comes from a direct-injected 1.0-liter engine that burns compressed hydrogen stored in a tank. Lexus didn't publish technical details so we don't know how much horsepower or torque the engine makes. Its cylinder count wasn't even published, though zooming in on the exhaust manifold confirms that it's a three-cylinder. It's likely not a coincidence that parent company Toyota tested a hydrogen-powered Corolla race car powered by a 1.0-liter hydrogen-burning triple earlier in 2021. That engine was turbocharged, however; this one is not. Looking at the center console reveals the ROV is equipped with a two-speed transfer case and locking differentials, so it should be capable off the beaten path. Lexus also tells us its first side-by-side offers users a large amount of suspension travel. Is this purely theoretical, or is Lexus serious about taking on Polaris? We've asked, and we'll update this story if we learn more. Related Video:      

2023 Lexus LC 500 and LC 500h get updated suspension system

Lexus is making a handful of changes to the LC for the 2023 model year. Again offered as a coupe and as a convertible, the firm's range topper gets an updated suspension system and a new paint color, among other changes, and it costs slightly more than the 2022 model. The most significant changes for 2023 are invisible to the naked eye. Lexus notes its engineers optimized the front and rear suspension to "enhance ground contact feel, linear steering response, and steering effectiveness in the high cornering G range." While the LC is more of a grand tourer than a track-ready sports car, these updates should make it more engaging to drive on a twisty road than the 2022 model. Buyers who prioritize handling can order an optional Sport Package that bundles a limited-slip differential, Yamaha performance dampers, performance brake pads, and Alcantara upholstery. While the package isn't new, it gains 21-inch forged alloy wheels for 2023. The only other visual change is a new color called Cloudburst Gray that Lexus charges $500 for. It bumps the number of available colors up to nine. Finally, every 2023 LC offers a 10-year subscription to the company's connected services. The drop-top LC also benefits from these updates, and it receives a lighter soft top as well as an optional feature called Climate Concierge that adds a few weeks to convertible season by keeping each passenger's upper body warm. The function can even direct warm or cold air to the back of the driver's hands. Lexus is not making mechanical changes to the LC for 2023. Power for the LC 500 comes from a naturally-aspirated, 5.0-liter V8 rated at 471 horsepower and 398 pound-feet of torque. It spins the rear wheels via a 10-speed automatic transmission, and it sends the coupe from zero to 62 mph in 4.4 seconds. While that's the LC Convertible's only engine option, the coupe is also offered with a gasoline-electric hybrid powertrain built around a 3.5-liter Atkinson-cycle V6 and rated at 354 horsepower. It shifts through both a CVT and a four-speed automatic. The new model year also brings a small price increase: the LC now starts at $94,600 including a $1,150 destination charge. Pricing for the full range is as follows: LC 500: $94,600 ($475 more than in 2022) LC 500h: $100,600 ($475 more than in 2022) LC 500 Convertible: $102,650 ($475 more than in 2022) On sale now, the 2023 Lexus LC will begin arriving on dealer lots in November 2022.
