2015 Lexus RC F

I didn't get a chance to drive the Lexus IS F until 2009, two years after the car had gone on sale, but I still vividly remember the day it happened. Having piloted almost every other vehicle in the Lexus lineup at that point, I was stoked to finally get some wheel time in the V8-powered, flared-fender muscle sedan, but fully expected the car to offer a quick, sanitized and ultimately un-driverly experience. Lexus built well-screwed-together, comfortable, quiet, reliable luxury cars for the timid, right?
As it turned out, I was 100-percent incorrect. When the premium brand's lauded "skunkworks team" crammed that massive V8 into the innocent IS, and then tuned the thing for competent hot laps at Fuji Speedway (F = Fuji, if you haven't heard), they seemingly forgot every brand value that Lexus had curated over the previous 20 years. It was raw and loud, had fast-twitch reflexes and a penchant for power slides, and it went unyieldingly across the road surface like a racecar cut loose from the paddock.
As far as Ur- models and origin stories go, the IS F and Lexus F has a pretty compelling, if new, set. A backdrop against which the sequel, this 2015 RC F, must inevitably be viewed. Sure, the otherworldly LFA may have intervened as the second F model, but the RC carries forward an evolution of the 5.0-liter V8 thumper, some shared body and chassis constructions, similar in-your-face design and a ticket price that's squarely in the mix for premium buyers with a hankering to smoke tires.

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."

2015 Lexus GS 450h also getting F Sport treatment

Lexus is making the 2015 model year version of the GS 450h a bit more appealing with the addition of 18-inch, split five-spoke wheels as standard equipment, and the optional F Sport package to really turn things up. The infotainment system is also getting a few, minor tweaks. Lexus has not officially released photos of the GS 450h F Sport, or a car with the updated wheels.
Previously exclusive to the GS 350, the F Sport package sharpens up the GS 450h behind the wheel to make it a bit more engaging. Ticking that box sharpens the adaptive suspension, especially in Sport S+ mode, and it adds 19-inch wheels with larger front brakes and high-friction pads, as well. If buyers want to go even further, the Lexus Dynamic Handling system is also available to add active rear steering, Lexus spokesperson Bill Kwong told Autoblog. The powertrain is left alone, though, and its hybrid-assisted 3.5-liter V6 producing 338 total system horsepower still returns 29 miles per gallon city, 34 mpg highway and 31 mpg combined.
The F Sport package also adds a mesh grille and new front bumper and, at the back end, buyers get a rear lip spoiler and revised lower valence panel. Inside, there's a sport driver's seat with 16-way power adjustability, a black headliner and added aluminum trim.
