Lexus RC F is a predatory sport coupe with a 450-horsepower beating heart

Take a look at that face. We can't be the only ones who see an automotive Predator staring back, right? Certainly, the Lexus RC F Coupe boasts a visually striking design that some are going to love and others are going to hate, but we can at least appreciate that it's aggressive, especially compared to the standard RC Coupe that we saw at the Tokyo Motor Show. And with good reason - there's a 5.0-liter V8 engine sitting under that massively domed hood with "more than 450 horsepower," along with a newly calibrated eight-speed automatic gearbox.
Interestingly, Lexus has tuned the RC F's engine to run on an Atkinson cycle under most circumstances, while it switches to the more typical Otto cycle when more power is required, presumably using some sort of advanced variable valve timing technology. Helping put that power to the ground with all those ponies wreaking havoc underhood is a torque vectoring differential, a first from Lexus.
Also involved in keeping the RC F planted is an aero package that includes wings and ducts galore. The headline bit is an active rear wing that deploys at 50 miles per hour and retracts back into the deck when the car drops back to 25 mph. A clear-coated carbon fiber roof can optionally join that carbon rear wing. There are apparently going to be three 19-inch wheel options, including the ones you see in our live image gallery above.

Google shares more details on self-driving car accidents

Google has pledged to release monthly reports on the status of its self-driving car program, and says these updates will include information on accidents involving the vehicles. But the company won't release the actual accident reports, a sore point for activists who recently have clamored for the company to be more transparent in the way it tests this promising technology on public roads. "Google is dribbling out bits of information in the hope to silence legitimate calls for full transparency," said John Simpson, privacy director for Consumer Watchdog, a nonprofit that has asked Google to release reports from the 12 accidents the company says it has been involved in over the past six years. "They are testing on public roads, and the public has a right to know exactly what happened when something goes wrong." Under California law, the accident reports are not considered public records. Google has attributed all accidents to human error, and says drivers of the other cars involved caused 11 of the 12 accidents. In eight of those, the Google cars were rear-ended, and the autonomous vehicles were sideswiped in two other crashes. One of the accidents occurred at an intersection when a human driver failed to yield at a stop sign, and in one incident, a Google driver accidentally rear-ended another car while manually driving. Google had previously provided those details. The first monthly report installment sheds new light on which types of self-driving vehicles were involved, directions of travel, locations, and whether the cars were operating in autonomous or manual mode. Update: Google says this information comes directly from the OL 316 forms used to report accidents involving autonomous cars in California, though it has "edited the summaries lightly to protect other drivers' information." But Google still will not release the original OL 316 forms, nor the "traffic collision report" forms used in California to report accidents. Another company that has been involved in a single self-driving car accident, Delphi Automotive, has released this information, which verified its car was not at fault. Regarding Google, Simpson said, "We now know a few more details of what happened. The problem is that it's Google's version and they want us to take their word for it." The Google self-report adds information that goes beyond accidents, with further details on the company's overall program.

2016 Lexus GS F First Drive [w/video]

Performance cars used to be about horsepower and chassis tuning. Lately the question isn't so much what's under the hood, but how many buttons are on the console. We're overwhelmed with individual settings for engine response, transmission, exhaust, steering, and ride. When did these cars turn into a choose your own tuning adventure? The Lexus GS F represents an attempt to step back from this over-adjustable madness and return to more bygone sports car values. It has a special engine, unique bodywork, and a chassis tuned for high performance. There are only two settings you need to play with. The first setting is the Drive Mode Select dial on the center console, which mainly controls the response of 5.0-liter V8 engine and the shift behavior of the eight-speed automatic. The engine is the same V8 found in the RC F, making the same 467 horsepower and 389 pound-feet of torque. New this year are small balancing weights on the crankshaft pulley that cut down on internal vibration. Drive Mode Select also changes the electronic power steering, air conditioning, and stability control (you can also turn it all the way off via a separate button). The engine is the same V8 found in the RC F, making the same 467 horsepower and 389 pound-feet of torque. You will use two settings in the GS F: Eco when you want to get somewhere, Sport S+ when you want to get somewhere fast. Normal and Sport S modes offer intermediate steps you don't really need. Eco mode softens the throttle and reduces the use of air conditioning for slightly better fuel economy. It also makes the center-mounted tachometer switch into an eco-driving gauge. S+ puts everything into sport mode, including a heavier steering weight and a higher stability control threshold. While Sport S mode shifts the noon position of the tachometer to just below the horsepower peak of 7,000 rpm, S+ goes a step further and turns the rev indicator into a solid bar that grows around the edge of the display. It also adds oil and coolant temperature to the readout. And how could we fail to mention G-Force Artificial Intelligence (or grin at such an overwrought name)? That's the shift logic the transmission uses in Sport S+. It's designed to hold revs in corners and downshift during hard braking. "Our goal with F is to make a driver's car, not a drag race winner." The other button in the Lexus GS F that you need to pay attention to is next to the Drive Mode Select knob, labeled TVD for Torque Vectoring Differential.
