Race Recap: 2013 Twelve Hours of Sebring, cakewalk up front, grindfest out back [w/spoilers]

This year's 12 Hours of Sebring wasn't exactly a foregone conclusion because we're still talking about racing, and anything can happen when the speeds are as high as the adrenaline and the desire. But we're still talking about Audi bringing it's two top-spec racers - and its huge budget and its nearly neurotic attention to detail - to a race that it uses as a test bed for The 24 Hours of Le Mans and as a way to open the endurance racing season with a victory.
Besides, 12 hours is a long time, especially at Sebring, and things didn't go all Audi's way. On top of that, although it was a pretty quiet race, behind the Audis things got even grimier, with plenty of battles, plenty of mechanical issues, and the new BMW Z4 GTE and Viper GTS-R being race tested. Oh, and that brand new chromed-out DeltaWing...

The Chevrolet Camaro 1LE returns with V6 or V8 power

The Chevy Camaro's performance variants are legendary, and enthusiasts have long lusted after the Z/28 and ZL1. But there's a lesser-known model that shouldn't be overlooked: the 1LE. It's Camaro code for performance on the track. The 2017 Camaro 1LE debuts this week at the Chicago Auto Show and goes on sale late this year. The 1LE package will be offered for the first time on V6 Camaros, as well as the traditional V8-powered SS. The cars have upgraded suspensions, better brakes, aerodynamic treatments that create more downforce, and improved cooling features. The goal is simple: faster laps. "This is all grip and handling and cooling," said Todd Christensen, Camaro marketing manager. It's an enthusiast special, transforming your basic Camaro into a more capable track machine. The 335-horsepower V6 and 455-hp V8 are unchanged (and only come with six-speed manual gearboxes), because the focus is on improving the Camaro's reflexes. That means different things, depending on the engine choice. Here's how they break down. V6 1LE The V6's 1LE package is based on the LT trim and it pilfers the best chassis pieces from the V8 model, including the FE3 suspension with stabilizer bars. It also has a mechanical limited slip differential (3.27 ratio) and four-piston Brembo brake calipers in front. The fuel system is also borrowed from the SS, and it all rolls on 20-inch forged aluminum wheels wrapped in Goodyear Eagle F1 rubber measuring 245/40R20 in front and 275/35R20 in back. Christensen says Chevy added the 1LE pack for the V6 because customers actively wanted it, and for a reasonable price (we hear the 1LE will cost about the same as the fifth gen's $3,500 option) they can transform their V6 into a car that's as track capable as the SS. While it's giving up 120 hp, a V6 Camaro 1LE will also be more than 200 pounds lighter than the eight-cylinder 1LE. Chevy noticed the customer interest for a V6 1LE and will study offering the pack on Camaros with the turbocharged four-cylinder engine. Consider the V6 a test case. "I'm anxious to get some customer feedback [from the V6]," Christensen said. SS 1LE Even though it's heavier, the SS 1LE offers a lot of goodies that make it three seconds faster than a normal SS, according to Chevy's testing at Willow Springs Raceway in the California desert. The spotlight features in the SS are Magnetic Ride Control for the FE4 suspension and electronic-slip differential (3.73 ratio).

2023 GM full-size SUVs get Super Cruise expansion pack first

In August, GM announced it had doubled the size of the network of roads available to its Super Cruise hands-free driving feature. Joining the options list in 2017, Super Cruise had been limited to divided interstate highways in the U.S. and Canada. The expansion opened 200,000 miles of additional divided interstate highway as well as major, undivided highways. Both coasts benefit, but there will be a lot more relaxing motoring on the East Coast especially. North of the border, six of the 10 Canadian provinces add enabled roads. Problem is, no GM vehicles have been able to take advantage of the boon. That changes this month, the automaker saying four of its full-size SUVs in specific trims are first in line to make use of the expansion. The SUVs are: 2023 Chevrolet Tahoe Premier and High Country 2023 Chevrolet Suburban Premier and High Country 2023 Cadillac Escalade, Escalade ESV, and Escalade-V 2023 GMC Yukon Denali Ultimate  The vehicles need to have been built on or after October 3, 2022, a production timeline GM says should put the first examples in customer hands this month. The least expensive way to get into Super Cruise is with the two-wheel drive, $77,625 Chevrolet Tahoe Premier with the 3.0-liter inline-six Duramax diesel and the Advanced Technology Package. Vehicles that use the GM's Vehicle Intelligence Platform electrical architecture and already have Super Cruise will receive an over-the-air update "in the coming months" to access the new roads, at no cost to owners. Since other products like the Cadillac CT4 and CT5, Chevrolet Silverado, and GMC Sierra work with the VIP platform as well, they probably aren't far away from the extra capability and they'll bring a lower financial bar to entry.  Related video:
