BMW M4 vs. Lexus RC F in Head 2 Head sports coupe showdown

It's the showdown everyone's been looking forward to, the East versus West grudge match of the year. We're talking, of course, about the BMW M4 versus the Lexus RC F.
Although BMW uses a twin-turbo straight-six and the Lexus uses a free-breathing V8, the two are pretty closely matched on paper: a luxury coupe with over 400 horsepower channeled to the rear wheels.
The BMW has been doing these cars for longer, and the M4 boasts a higher power-to-weight ratio. But then the RC F has more power - and without forced induction to break up the rev range. So which is the better luxury muscle coupe? Watch the latest episode of Motor Trend Head 2 Head to find out.

Next Lexus RX previewed with JDM Toyota Harrier?

Japanese site CarWatch has revealed images of the next-generation Toyota Harrier, known to US and European buyers as the Lexus RX. The new model features a considerably more aggressive fascia in keeping with some of the latest Lexus design trends, while the back features a pair of wide, wraparound taillights.
The profile features a revised greenhouse, with a rather complex rear window treatment, while a subtle character line connects the front and rear taillights. According to the badging, the model shown features a hybrid powertrain, although there's little information on which engine is being used. We'd wager it's an evolution of the same 3.5-liter V6 hybrid found in the current RX450h.
This early look doesn't have a great deal of other info, and there are no images of the interior. We're not yet clear on how closely the North American RX will adhere to the Harrier seen here, but historically the two models have been quite close. That said, we'd expect a more prominent 'spindle' grille on the Lexus version than the baleen strainer on the vehicle shown here.

Toyota and Lexus show off advanced safety research vehicle [w/video]

While Google and Audi explore the possibilities of autonomous vehicles, Toyota and its Lexus division are studying the intermediate step of vehicles equipped with a deep suite of technology that help drivers make the best decisions. Introduced at this week's Consumer Electronics Show in Las Vegas, the Lexus advanced safety research vehicle is an LS sedan fitted with three high-def color cameras to detect objects up to almost 500 feet away, 360-degree Light Detection and Ranging (LIDAR) lasers that can detect objects up to 220 feet away, three radar units to keep track of other vehicles at intersections, a precision odometer on the rear wheel, GPS that estimates orientation and an accelerometer.
Currently testing at a purpose-built 8.6 acre urban testing ground at the Higashi-Fuji Technical Center in Susono, Japan the Toyota research vehicle is being used to study how to make better drivers, as well as figuring out how to reduce crashes as the industry's journey through passive and active safety systems progresses. In the event of a crash, new rescue systems are also being tested.
Further investment is being put into the Intelligent Transportation System (ITS) that would use shortwave signals to harness information from the car and from other vehicles on the road, as well as roadside infrastructure and even pedestrians. Toyota reasons it could then build a picture of interactions and, for instance, alert the driver to a potential collision at a blind intersection.
