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."

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.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.
