Google’s new self-driving cars cruising Silicon Valley roads

SAN FRANCISCO, United States — The latest models of Google’s self-driving cars are now cruising the streets near the Internet company’s Silicon Valley headquarters as an ambitious project to transform the way people get around shifts into its next phase.

This marks the first time that the pod-like, two-seat vehicles have been allowed on public roads since Google unveiled the next generation of its self-driving fleet more than a year ago. The cars had previously been confined to a private track on a former Air Force base located about 120 miles southeast of San Francisco.

Google announced last month that it would begin testing the curious-looking cars last month, but hadn’t specified the timing until Tuesday when it disclosed the vehicles are driving up to 25 miles per hour on the roads around its Mountain View, California, office.

Google had installed its robotic driving technology in Lexus sports utility vehicles and Toyota Priuses during the first few years of testing before developing the smaller prototype. The new models are designed to work without a steering wheel or brake pedal, although the vehicles will be equipped with those features during the initial runs on public roads.

A human will also ride in the cars to take control in emergencies, just as has been the case with the self-driving Lexus vehicles during the past six years.

The debut of the pod-like car will help Google get a better understanding on how well its technology works around other vehicles steered by people.

Last year, Google Inc. told reporters it hoped to have a 100 of the self-driving prototypes in its fleet by now, but the company said it has only built 25 of them so far. All 25 have received permission from California’s Department of Motor Vehicles to drive neighborhood roads.

If all goes well, Google hopes to gain regulatory clearance to remove the steering wheel, brake pedal and emergency driver from the prototype. Company executives have expressed hope that self-driving cars using its technology will be joining the flow of daily traffic by the end of this decade.

The earlier models of Google’s self-driving cars had been involved in 13 minor accidents through more than 1.8 million miles on the roads, according to the company. Google blamed the collisions on other vehicles in every instance except one when the company says one of its own employees was steering.

Detroit 2014: Lexus to launch V8-powered RC F coupe

Giving new meaning to “back to the grind,” the daily commute is now transformed into a day at the track with the all-new Lexus RC F. The RC F coupe is styled to support the most powerful V8 performance car ever developed by Lexus.

Based on the spectacular all-new RC coupe that was revealed at the Tokyo Motor Show last November, the RC F has wider wheels and tires, an active rear wing, air scoops, cooling ducts and available carbon fiber components, each delivering uncompromising grit to the driving experience.

Design Exterior

The signature Lexus spindle grille, featuring a subtle F-pattern on the lower half, dominates the front of the RC F from the bottom of the hood to the lower lip. The hood is higher than that of the RC to accommodate the larger V8 engine and create the powerful flared profile suited to an F model. Ducts beneath the front bumper, fenders, and strategically-placed aerodynamic stabilizing fins create a stance which further identifies the F model.

Air outlets at the rear of the front fender form the shape of an L when they merge with side sill extensions, while stacked trapezoidal quad-outlet tailpipes at the rear add further aggression. Taking design cues from the Lexus LFA supercar, the RC F features an available speed-sensitive active rear spoiler. It enhances the coupe’s lines at standstill and deploys from the RC F’s deck at approximately 50 mph and retracts when the speed is less than 25 mph. The wing helps the RC F maintain traction and stability at higher speeds.

Three variations of 10-spoke 19-inch forged aluminum wheels are available, including two machine polished designs and one design hand polished by a craftsmen.

Design Interior

The striking cockpit-like interior of Lexus RC F complements the aggressive exterior. Unique components include the meters, steering wheel, seats, ornamentation and pedals. The instrument panel is dominated by a central meter which changes according to the four selectable driving modes. The information, color of the display and size of text can be changed.

Occupant comfort is all important. RC F debuts a Lexus-first elliptical cross-section thick-grip steering wheel with optimum placement of paddle gear shifts. All-new high back seats with an embossed F on the headrests offer the driver and passenger an exceptional performance fit. The seats are available in a selection of five leather trims, each with contrasting stitching.

Outstanding new L-shaped rubber slits in the brake and accelerator pedals combine form and function to provide better foot grip.
