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.

Before Chevrolet's Redline, there was the Saturn Red Line

While Chevy rolls out Redline special editions across more of the lineup at this year's Chicago Auto Show, we've been eating some 'member berries and started thinking about the last time GM used the term. Back in 2004, Saturn rolled out Red Line (two words) editions of the Ion and Vue. The lineup was joined by the Sky Red Line in 2007, and the second-generation Vue kept the tradition going in 2008. This was in the heady days of the mid-2000s, before the financial crisis and GM's bankruptcy reorganization that saw the end of Saturn. The press release headline for the 2008 Sky is now cringe-worthy: "Hot-selling Sky helps drive Saturn product renaissance." Performance lineups were the hot new thing, as automakers attempted to cash in on the tuner trend popularized by The Fast and the Furious. Chevy had SS models, Pontiac had GXP, and Saturn had Red Line. Across the Detroit Metro area, Dodge had a slew of SRT models, and Ford's Special Vehicle Team brought us the SVT Lightning pickup, the SVT Focus, and a smattering of hopped-up Mustangs. The performance cred of Red Line models varied from car to car. The Ion Red Line shared the same engine as the original Chevy Cobalt SS, a 205-horsepower supercharged 2.0-liter four-cylinder, 65 hp more than stock. Car and Driver tested one with a 0-to-60-mph time of 6.1 seconds and said the Ion "tears down the wall that has separated enthusiasts from the Saturn brand for so long." The Vue Red Line, meanwhile, came with the same optional Honda-sourced 3.5-liter V6 you could get in the regular Vue, and added a stiffer, lower suspension, bigger wheels with more aggressive rubber, and recalibrated steering assist. When the Vue was redesigned for the 2008 model year, the Vue Red Line was a similar proposition. The engine was now from GM, and up 7 horsepower to 257, but you could get it in both Red Line and XE trim. Aside from the tire and suspension upgrades, Red Line models now came with a unique front fascia and rear exhaust cutouts. The most exciting Red Line, of course, was the high-performance version of the Sky roadster, which shared underpinnings with its Pontiac Solstice twin. This model came with GM's hot 2.0-liter Ecotec Turbo, good for 260 horsepower. The extra power was crucial in covering up the Sky's unfortunate manual gearbox ratios, which left the non-turbo model aching for torque in lower gears. As we all know, Saturn was taken by the grim reaper in 2009 after an attempt to sell the brand to the Penske Group.

2020 Chevy Corvette Stingray vs the world: How it compares on paper

The 2020 Chevy Corvette Stingray in its base form offers an astonishing amount of performance for the money. In fact, so impressive is the car's spec sheet that the Corvette kind of exists in two different competitive sets: one of cars priced similarly, and another with cars of similar performance and reputation. To get a feel for how it handles each of these segments, we've compiled specifications for those two sets of players. You can find the first set below, which looks at cars of roughly the same price point. Following that is a bit of analysis, and then there's a chart of cars with similar performance and reputation. And that chart will also have some analysis. Though final pricing for the Corvette hasn't been announced yet, we know the Corvette will start at less than $60,000. And as far as pricing goes, its closest competitor is the Porsche 718 Cayman, which also starts at just under $60,000. Both are mid-engined and rear-drive, but the Corvette offers an extra 195 horsepower and 190 pound-feet of torque. The Cayman does boast a curb weight of right around 3,000 pounds, so it weighs a few hundred pounds less than the Corvette, but it's likely not enough to make up for the power deficit. The Corvette's sub-3.0-second 0-60 time bears this out against the Cayman's best 4.5-second run. Impressively, though, the Cayman has more cargo space than the Corvette in a package that's nearly 10 inches shorter. The Cayman also still offers a manual option for those that prefer self-shifting. The 2020 Toyota Supra is on the cheap end of this sports car class, just crossing $50,000. It also boasts more power than the Cayman, though it's still down by 160 ponies and 105 pound-feet of torque to the C8. It's also about as roomy as the Corvette, despite being about the same size as the Cayman. Cargo space is a bit tighter. Its driving characteristics will likely differ, too as the Supra sits on a front-engine platform. It might even feel closer to a C7 Corvette in some ways. The other mid-engine entry in this price range is the 2019 Alfa Romeo 4C Spider. Its small 1.7-liter turbo inline-4 only makes 237 horsepower and 258 pound-feet of torque, but it's also far and away the lightest of this group at 2,487 pounds. That's roughly 1,000 pounds lighter than the Corvette. It isn't as fast as the Corvette in a straight line, but that lightness surely pays dividends in cornering and braking.
