See the Ferrari F12tdf’s rear-wheel steering system in action

By Stephen Edelstein Published October 16, 2015

One of the highlights of the Ferrari F12tdf unveiled earlier this week is its “Virtual Short Wheelbase” rear-wheel steering system. Ferrari isn’t the first manufacturer to try rear-wheel steering, and like the others who have, it claims these systems can increase handling agility. But how exactly does it do that?

As detailed in the video above, the Ferrari system steers the rear wheels in the same direction as the front wheels when entering a corner. This allows the car to turn in more quickly, effectively making it better at devouring more sections of road or track. Ferrari also claims the system allowed it to fit wider front tires to the F12tdf.

The exact amount of rear-wheel steering angle is determined by a model-based control logic that takes into account steering-wheel angle, the speed of steering inputs, and the vehicle’s speed. Ferrari claims this system will allow customers to take better advantage of the F12tdf’s performance by improving responsiveness, as well as high-speed stability.

Ferrari isn’t the only carmaker that thinks steering more wheels is better. Porsche introduced a rear-wheel steering system on the 911 Turbo, GT3, and GT3RS, which is now migrating to more mainstream 911 models. It has the ability to steer the rear wheels in the opposite direction of the front wheels to improve maneuverability at low speeds, making the cars easier to park. It also steers the rear wheels with the fronts at higher speeds for better handling.

Rear-wheel steering was also one of the “it” technologies on 1990s Japanese performance cars like the Honda Prelude and Mitsubishi 3000GT VR4, and was even offered on General Motors pickup trucks for a time. But this nifty-sounding feature just hasn’t made much of an impression with consumers in the past.

But even if buyers aren’t impressed by the rear-wheel steering, there’s still plenty about the F12tdf that should attract attention. Named after the Tour de France endurance race, it features an upgraded version of the standard F12 Berlinetta’s 6.3-liter V12, with 780 horsepower and 520 pound-feet of torque. It’s also got a faster-shifting transmission, numerous aerodynamic upgrades, and a lighter curb weight.

F12tdf production will be limited to 799 units, priced at an undisclosed amount you probably can’t afford.

Tesla, Warner Bros. dodge some claims in ‘Blade Runner 2049’ lawsuit, copyright battle continues

Tesla Cybercab at night

Tesla and Warner Bros. scored a partial legal victory as a federal judge dismissed several claims in a lawsuit filed by Alcon Entertainment, a production company behind the 2017 sci-fi movie Blade Runner 2049, Reuters reports.
The lawsuit accused the two companies of using imagery from the film to promote Tesla’s autonomous Cybercab vehicle at an event hosted by Tesla CEO Elon Musk at Warner Bros. Discovery (WBD) Studios in Hollywood in October of last year.
U.S. District Judge George Wu indicated he was inclined to dismiss Alcon’s allegations that Tesla and Warner Bros. violated trademark law, according to Reuters. Specifically, the judge said Musk only referenced the original Blade Runner movie at the event, and noted that Tesla and Alcon are not competitors.
"Tesla and Musk are looking to sell cars," Reuters quoted Wu as saying. "Plaintiff is plainly not in that line of business."
Wu also dismissed most of Alcon's claims against Warner Bros., the distributor of the Blade Runner franchise.
However, the judge allowed Alcon to continue its copyright infringement claims against Tesla for its alleged use of AI-generated images mimicking scenes from Blade Runner 2049 without permission.
Alcan says that just hours before the Cybercab event, it had turned down a request from Tesla and WBD to use “an icononic still image” from the movie.
In the lawsuit, Alcon explained its decision by saying that “any prudent brand considering any Tesla partnership has to take Musk’s massively amplified, highly politicized, capricious and arbitrary behavior, which sometimes veers into hate speech, into account.”
Alcon further said it did not want Blade Runner 2049 “to be affiliated with Musk, Tesla, or any Musk company, for all of these reasons.”
But according to Alcon, Tesla went ahead with feeding images from Blade Runner 2049 into an AI image generator to yield a still image that appeared on screen for 10 seconds during the Cybercab event. With the image featured in the background, Musk directly referenced Blade Runner.
Alcon also said that Musk’s reference to Blade Runner 2049 was not a coincidence as the movie features a “strikingly designed, artificially intelligent, fully autonomous car.”

Audi halts vehicle deliveries to the U.S. as it mulls impact of tariffs

2021 Audi Q5

If you’d been thinking of buying an Audi, now might be the time. The German brand, owned by the Volkswagen Group, has announced it would halt shipments to the U.S. in the wake of President Donald Trump’s 25% tariffs on all imported vehicles.
Audi is currently holding cars that arrived after the tariffs took effect, on April 3, in U.S. ports. But it still has around 37,000 vehicles in its U.S. inventory, which should be able to meet demand for about two months, according to Reuters.
Automakers on average hold enough cars to meet U.S. demand for about three months, according to Cox Automotive.
Audi should be particularly affected by the tariffs: The Q5, its best-selling model in the U.S., is produced in Mexico, while other models, such as the A3, A4, and A6 are produced in Germany.
Holding shipments is obviously a temporary measure to buy time for Audi and parent company Volkswagen. If tariffs stay in place, vehicle prices would likely have to go up accordingly, unless some production is shifted to the U.S. Volkswagen already has a plant in Chattanooga, Tennessee, and is planning a new plant in South Carolina. That latter plant, however, isn’t expected to be operational until 2027 and is currently dedicated to building electric vehicles for VW’s Scout Motors brand.
Other global automakers have also taken drastic measures in response to Trump’s tariffs. Jaguar Land Rover on April 5 said it is pausing shipments of its its UK-made cars to the United States this month. The British sports-luxury vehicle maker noted that the U.S. market accounts for nearly a quarter of its global sales, led by the likes of Range Rover Sports, Defenders, and Jaguar F-PACE.
And on April 3, Nissan, the biggest Japanese vehicle exporter to the United States, announced it will stop taking new U.S. orders for two Mexican-built Infiniti SUVs, the QX50 and QX55.

Waymo faces questions about its use of onboard cameras for AI training, ads targeting

Two people exit a Waymo taxi.

In an iconic scene from the 2002 sci-fi film Minority Report, on-the-run Agent John Anderton, played by Tom Cruise, struggles to walk through a mall as he’s targeted by a multitude of personalized ads from the likes of Lexus, Guinness and American Express, everytime hidden detectors identify his eyes.
It was clearly meant as a warning about a not-so-desirable dystopian future.
Yet, 23 years later that future is at least partlially here in the online world and threatens to spread to other areas of daily life which are increasingly ‘connected’, such as the inside of cars. And the new testing grounds, according to online security researcher Jane Manchun Wong, might very well be automated-driving vehicles, such as Waymo’s robotaxis.
On X, Wong unveiled an unreleased version of Waymo’s privacy policy that suggests the California-based company is preparing to use data from its robotaxis, including interior cameras, to train generative AI models and to offer targetted ads.
“Waymo may share data to improve and analyze its functionality and to tailor products, services, ads, and offers to your interests,” the Waymo’s unreleased privacy statement reads. “You can opt out of sharing your information with third parties, unless it’s necessary to the functioning of the service.”
Asked for comments about the unreleased app update, Waymo told The Verge that it contained “placeholder text that doesn’t accurately reflect the feature’s purpose”.
Waymo’s AI-models “are not designed to use this data to identify individual people, and there are no plans to use this data for targeted ads,” spokesperson Julia Ilina said.
Waymo’s robotaxis, which are operating on the streets of San Francisco, Los Angeles, Phoenix and Austin, do contain onboard cameras that monitor riders. But Ilina says these are mainly used to train AI models for safety, finding lost items, check that in-car rules are followed, and to improve the service.
The new feature is still under development and offers riders an opportunity to opt out of data collection, Ilina says.
But as we all get used to ads targeting based on everything that’s somehow connected to the web, it seems a once-distant vision of the future may be just around the corner.
