What does the open patents deal mean for Tesla ... and BMW?

Gift to the world or trade bait? Tesla Motors announced this week it would open its patents for other automakers to use. That has analysts guessing whether the California-based electric-vehicle maker is looking to either swap trade secrets with other automakers or to expand the proverbial pie that represents the plug-in vehicle market. For its part, Tesla says the answer is B. BMW, which is establishing its i sub-brand of plug-in vehicles, would be a natural collaborator with Tesla, Forbes says. In fact, executives from the two companies met in Europe this week. Details were not released, but a BMW spokesman said, "Both companies are strongly committed to the success of electromobility and discussed how to further strengthen the development of electromobility on an international level." While Tesla brings battery technology to the table, BMW offers its carbon-fiber advancements that lighten vehicle-body weight. Those advancements are key to range-extending efforts and could do wonders for Tesla on its journey to help spur technology for the sake of getting more of the general public to accept plug-in technology as a viable first-car option. Then again, Forbes says Tesla, whose investors include Mercedes-Benz parent Daimler and Toyota, may be keeping its best technologies to itself by not patenting certain advancements at all. What's in Tesla's patent pool? uAutoInsurance analyzed Tesla's 249 patents and found that 104 of them related to battery technology, while 28 pertained to recharging activity, which wasn't surprising (about a quarter of those 249 patents couldn't readily be categorized). Tesla also has nine patents related to sunroof technology. The company is based in California, after all.

Drive like a prince: Join us for a walk through Monaco's car collection

Small, crowded, and a royal pain in the trunk lid to drive into during rush hour, Monaco sounds like an improbable location for a huge car museum. And yet, this tiny city-state has been closely linked to car culture for over a century. It hosts two major racing events every year, many of its residents would qualify for a frequent shopper card if Rolls-Royce issued one, and Prince Rainier III began assembling a collection of cars in the late 1950s. He opened his collection to the public in 1993 and the museum quickly turned into a popular tourist attraction. The collection continued to grow after his death in April 2005; it moved to a new facility located right on Hercules Port in July 2022. Monaco being Monaco, you'd expect to walk into a room full of the latest, shiniest, and most powerful supercars ever to shred a tire. That's not the case: while there is no shortage of high-horsepower machines, the first cars you see after paying ˆ10 (approximately $11) to get in are pre-war models. In that era, the template for the car as we know it in 2023 hadn't been created, so an eclectic assortment of expensive and dauntingly experimental machines roamed whatever roads were available to them. One is the Leyat Helica, which was built in France in 1921 with a 1.2-liter air-cooled flat-twin sourced from the world of aviation. Fittingly, the two-cylinder spun a massive, plane-like propeller. Government vehicles get a special spot in the museum. They range from a Cadillac Series 6700 with an amusing blend of period-correct French-market yellow headlights and massive fins to a 2011 Lexus LS 600h with a custom-made transparent roof panel that was built by Belgian coachbuilder Carat Duchatelet for Prince Albert II's wedding. Here's where it all gets a little weird: you've got a 1952 Austin FX3, a Ghia-bodied 1959 Fiat 500 Jolly, a 1960 BMW Isetta, and a 1971 Lotus Seven. That has to be someone's idea of a perfect four-car garage.  One of the most significant cars in the collection lurks in the far corner of the main hall, which is located a level below the entrance. At first glance, it's a kitted-out Renault 4CV with auxiliary lights, a racing number on the front end, and a period-correct registration number issued in the Bouches-du-Rhone department of France. It doesn't look all that different than the later, unmodified 4CV parked right next to it. Here's what's special about it: this is one of the small handful of Type 1063 models built by Renault for competition.

Ring Taxi BMW M3 chases an Aventador SV and Cayman GT4

On paper, a BMW M3 that's loaded with three passengers probably shouldn't have a chance at keeping up around a track with a Porsche Cayman GT4 and a Lamborghini Aventador LP 750-4 Superveloce. In the real world, driver skill and track knowledge can make all the difference, though. And when the M3 is a Nurburgring Taxi with a driver that knows the course incredibly well, we end up getting a fantastic lap like this one. The 'Ring Taxi driver starts by teasing his passengers that they'll see whether the Lambo is fast. Before the two of them get on track, the GT4 cuts in to join the party. What follows is a fascinating lap of the Nordschleife. It's impressive how the BMW driver's skill allows him to keep up with the two other cars and blow past tons of other traffic. During faster sections, the Porsche and Aventador start to pull away, but as soon as the course gets curvy again, the M3 is right back in the action. As the group pulls back into the parking lot, even the Ring Taxi driver sounds impressed with his performance. See the impressive show in the video above. Related Video:
