Watch how Corvette Racing's new collision-avoidance radar system works

When it comes to technology used in racecars, we generally expect it to trickle down to production cars, not the other way around. Well, Pratt & Miller has developed a new rear-facing radar that operates in a similar fashion to what we're used to in modern blind spot detection systems, only it is also capable of tracking cars as they approach and relaying vital information to the driver via a large display screen.
The innovative radar system debuted at last weekend's 12 Hours of Sebring for Corvette Racing, and this system makes perfect sense for endurance races like this since the cars sometimes have to drive through the night and in poor weather conditions.
The radar can detect cars even with poor visibility, and uses easy-to-distinguish symbols for the driver to identify.

2020 Ford Escape hybrids vs other crossover fuel sippers: How they compare on paper

Along with a new generation of Escape, Ford also reintroduced the world to the 2020 Ford Escape Hybrid. And if that weren't enough, Ford is adding a plug-in hybrid version. This is a sign of the times: people are more crossover crazy than ever, but are also seeking ways to use less fuel, whether it's for environmental or purely money-motivated reasons. The Ford hybrids aren't the only fuel-efficient compact crossovers on the market. They will be going head-to-head with conventional hybrids including the 2019 Kia Niro, 2019 Nissan Rogue Hybrid and 2019 Toyota RAV4 Hybrid. There are other plug-in hybrids including the 2019 Subaru Crosstrek PHEV, 2019 Mitsubishi Outlander PHEV and the plug-in version of the 2019 Kia Niro. There are even a couple diesels in the form of the 2019 Chevy Equinox and 2019 GMC Terrain. So we've rounded up the details on all these crossovers to see who leads and lags in criteria such as power, fuel efficiency, space and price. Check out all their details below. 2019 Subaru Crosstrek Hybrid View 68 Photos How do their engines and fuel economy compare? Conventional Hybrids and Diesels Let's face it, if you're buying one of these crossovers, one of the things that matters most to you is just how frugal with fuel they are. We'll start off with the conventional hybrids and diesels, and the clear victor is the Kia Niro, which in base FE trim, manages to hit 50 mpg combined. This is thanks to it sharing its powertrain with the Hyundai Ioniq, the Hyundai equivalent of the Toyota Prius. Buyers should take note that only the FE returns such high fuel economy. The LX and EX drop to 49 mpg, and the S Touring and Touring get 43. Even then, the least efficient Niro is the most efficient of the normal hybrids and diesels. It is nearly the least powerful, though, with 139 horsepower. Just behind it is the Toyota RAV4 Hybrid. It delivers 40 mpg combined, and it has an ace up its sleeve: it comes standard with all-wheel drive. Every other vehicle in this powertrain group has front drive standard, and the Niro isn't available with all-wheel drive at all. If that weren't enough, the RAV4 Hybrid also boasts the most power at 219 horses. While we can't say anything about Escape Hybrid fuel economy, we do know that it will make 198 horsepower, which is close to the class-leading RAV4. The least powerful of these is the Equinox and Terrain, and they return the worst fuel economy at 32 mpg.

How long will the 'golden age' of performance last?

High-powered sports and luxury cars were everywhere at the New York Auto Show, prompting the obvious question for enthusiasts: How long will this golden age of performance last? Industry leaders have some time before regulations elevate the Corporate Average Fuel Economy level in 2025. Even then, they expect cars rippling with power to survive in some form. "Is it the end of an era," I don't think so," said Ola Kallenius, Daimler AG board member for Mercedes-Benz cars marketing and sales. "That performance element of individual mobility I don't think will ever go away." Kallenius, who oversaw the company's AMG division from 2010-2013, expects it to continue to grow. Last year, AMG sold a record 68,875 units around the world, an increase of 44.6 percent over 2014, with strong growth in the US, China, and Germany. Still, there's always the potential for gas to spike, and pending fuel economy regulations are looming. That could lead AMG to add electrification to its products, Kallenius said, pointing to the electric SLS as a test case. Chevy is also thinking ahead, said Al Oppenheiser, chief engineer of the Camaro. He wouldn't bite when asked about electrification for the Camaro (he did say "never say never"), but admitted in 2025 "it's going to be pretty tough to sell V8s." For now, things are rosy for muscle cars, and Chevy confidently showcased the 640-hp Camaro ZL1 in coupe and convertible form in New York. "I think that this is truly the golden age of performance," Oppenheiser said. It's hard to disagree. News & Analysis News: The 2017 Mazda MX-5 Miata RF was a show-stopper in New York. Analysis: There was a palpable energy when this RF — for Retractable Fastback — was revealed the night before the show at a trendy off-site venue near the Hudson River. Even as a parade of SUVs and flashy luxury cars rolled out the rest of the week, the Miata remained a hot topic. The Retractable Fastback is really a clever targa top, with part of the roof stowing behind the seats, adding about 100 pounds compared to the standard convertible. It makes the car more practical and arguably more attractive. The RF continues Mazda's tradition of selling the Miata with a hardtop variant. The first and second generations offered a detachable one, and a power retractable hardtop (a $1,700 option) was available on third-gen models. Judging by its reception in New York, the RF could prove to be even more popular than its predecessors.
