Chris Harris flogs the Lexus RC F

Chris Harris went to the Monticello race track in New York to sample the Lexus RC F, and, to be honest, he had to figure out how to love it on a circuit. Smitten with the luxury coupe's looks and cabin and naturally-aspirated V8 before taking the driver's seat, Harris found that four laps on track exposed its Achilles' heel: mass. Harris quoted the weight of his car at 1,860 kilograms, or 4,092 pounds, which is about one junior varsity athlete beyond the 3,958-pound curb weight of the coupe we drove. The 478 horsepower and 391 pound-feet of torque couldn't stoke the hustle Harris wanted, removing all the easy friskiness expected from the coveted FR setup, and leading to quick brake fade. He made note of the Lexus' lack of torque compared to the BMW M4, but in truth the RC F is only 15 lb-ft shy of its Munich nemesis. It is, however, at least 400 pounds heavier. On public roads, though, it's a different story. When not being pushed to prove itself in tight spaces, Harris thinks the Lexus is still a "curious blend of things," but a GT whose noise, styling and non-Germanness mean that it "certainly has a place," and might just take time to grow into.

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 planning second flagship alongside LS sedan

Lexus is planning to launch another flagship to slot alongside the LS sedan, but we don't know if it will be a coupe or a crossover. The coupe has been the persistent rumor. Lexus showed the two-door LF-LC concept in 2012 and a production model could borrow its underpinnings from the LS sedan. It's tipped to wear the letters LC or to revive the SC nameplate. The previous SC launched in 1991 as a fixed-roof coupe and offered inline-six or V8 engines. It was replaced in 2001 with the SC430 that had a V8 and a folding hardtop. While the coupe idea may seem like the leading candidate, the company's ambiguity is leading to speculation that the new flagship could adopt a different body-style altogether. "We need a flagship," Lexus general manager Jeff Bracken told Reuters. "It doesn't have to be a sedan." "In addition to the LS, there could be another flagship in our lineup," Bracken said. "We'll define what it is in January." The comments suggest something will be revealed at the Detroit auto show and could open the door to a new flagship SUV or crossover. That position is currently held by the LX 570, which is closely based on the Toyota Land Cruiser. However, sales of the LX have been less than stellar. From the 14,000-plus units Lexus sold of the original LX 470 when it launched in the US back in 2000, annual sales have dropped to just over 4,000 the last few years. Mercedes regularly sells over 25,000 of its GL-Class crossovers each year in the US alone. Last year Audi sold 18,000 Q7s here despite its imminent replacement. Land Rover sold nearly 13,000 Range Rovers last year and another 18,000 Range Rover Sports. Meanwhile, Cadillac typically sells between 20,000 and 30,000 Escalades every year, down from the 50,000-60,000 it sold a decade ago. A facelift is due for the LX that ought to spike sales a little, but Lexus will need more than a refresh to catch up with those rivals. In the meantime, it reportedly plans to roll out a three-row variant of the new RX before its lifespan is over. "We don't want to wait for a next generation" to give the RX the added seating capacity many customers are demanding, said Bracken. Related Video:
