Cadillac back on track with 600-hp ATS-V.R racer in FIA GT3 spec [w/video]

There was already a rumor brewing that Cadillac might eschew the CTS as its racecar next season in favor of the ATS Coupe. It turns out that is absolutely the case, and now we know just what this 600-horsepower, future racer looks like. The coupe might not be limited to competing in just the US, though, because it's built to FIA GT3-specifications, meaning that this Caddy is also eligible to race in over 30 series worldwide against the likes of Bentley, McLaren, Audi and other premium brands.
The heart of this massively winged Cadillac is an engine dubbed the LF4.R. It's based around the unit in the production ATS-V and CTS Vsport but with larger turbos, bigger intercoolers, side exhausts and other tricks. Cadillac claims it makes a monstrous 600 hp and 520 pound-feet of torque in unrestricted form.
As the photo above shows, the ATS-V.R also wears an aggressive aero kit with a carbon fiber front splitter, and a wing at the back that could probably double as a picnic table in a pinch. The dry weight of the whole package is quoted at about 2,900 pounds, which is around 700 pounds less than the street version.

How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.

GM Super Cruise beats Tesla Autopilot again in latest hands-free test

DETROIT — General Motors' Super Cruise once again edged Tesla's Autopilot in an evaluation of 17 vehicles equipped with active driving assistance systems (ADAS) by Consumer Reports, the testing organization said on Wednesday. A Tesla Model Y fitted with Autopilot finished "a distant second," the group said, to a Cadillac CT6 equipped with Super Cruise, which GM is rolling out to more than 20 vehicles — including its new Hummer electric pickup truck — over the next three years. Safety and insurance researchers have frequently warned of the risks of consumers overestimating ADAS systems' abilities, a misconception increased by some automakers calling their products Autopilot, ProPilot or Co-Pilot. In 2018, the Cadillac CT6 with Super Cruise scored higher than a Tesla Model 3 with Autopilot, in a Consumer Reports test of just four vehicles equipped with ADAS. In the latest test, conducted this summer on a track and on public roads, the Cadillac scored 69 points out of a possible 100, while the Tesla scored 57. A Lincoln Corsair equipped with Ford's Co-Pilot 360 system, finished third with 52. The critical difference in the Super Cruise system is a driver-facing infrared camera to make sure he or she is paying attention to the road and is ready to take over manual control when necessary, said Kelly Funkhouser, head of connected and automated vehicle testing at Consumer Reports. The group noted that Autopilot can shut off abruptly in some situations, while Super Cruise did a better job of notifying the driver when the system is disengaging. In recent European safety testing, a Tesla Model 3 with Autopilot placed sixth out of 10 systems, getting high marks for performance and ability to respond to emergencies, but falling short on its ability to maintain a driverÂ’s focus on the road.
