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.

Anti-EV, pro-hybrid ad from Lexus gets a whole lot wrong

Tell us if you're surprised that Toyota (through its Lexus brand) is putting out some questionable information about electric vehicles. While it's one thing for company executives to be anti-EV, it's quite another to put out obviously false information when you speak ill of plug-in vehicles, especially when you also sell them. The automaker offers the RAV4 EV and Prius Plug-In, albeit in limited numbers, First, let's look at what Lexus is saying. On the company's consumer site, in the hybrid section, there are a number of slick videos. In one ("Hybrid Overview"), Lexus makes it look like charging an EV takes four hours. That may be true in some situations, but the video shows an anonymous driver plugging a Nissan Leaf into something that looks like a AeroVironment DC fast charger, which takes around a half hour to charge. Granted, the site has a disclaimer that says, the "charge time represents the average time to charge from empty to full using typically available 240V commercial charging stations," but in everyday use, that's not something EV drivers often do. Charged EVs mentions two previous studies that show how most EV charging is done at home. Lexus knows all this, of course, but doesn't mention it. Lexus says that there are 20 states with an "established infrastructure" for hydrogen. Another video on the site, one that talks about future alternative powertrain technologies, says that there are 20 states with an "established infrastructure" for hydrogen and 37 with the same for electric vehicles. It also blatantly says that we need to consider all of the emissions from the fossil fuels used to make electricity (carbon monoxide, sulfur dioxide, etc.) but does not say anything about the fossil fuel emissions used to make hydrogen. You can see some screen grabs in the gallery or watch the video yourself. It's all blatantly one-sided, especially since the official numbers from the Department Of Energy say that there are Level 2 public EV chargers in literally every state except Alaska and only 11 public hydrogen stations in the US. Ten of them are in California, the other is in South Carolina. A Lexus spokesman told AutoblogGreen it will ask TeamOne, its ad agency, and the Lexus marketing department for clarification on where the data in the videos comes from. We will update this post when we hear back.

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."
