Dodge Challenger SRT Hellcat vs. Chevrolet Camaro ZL1 in latest Head 2 Head

"Olympian" is one of the terms we use to signify the greatest height, the seat of the gods. Yet Mt. Olympus is the second-highest peak in the Balkans ranges, overshadowed by the crest at Musala in Bulgaria's Rila mountains. Both great heights, but one is a little higher. That's how we get the Olympian Chevy Camaro ZL1 pitched at the Musalic Dodge Challenger SRT Hellcat in Motor Trend's latest episode of Head 2 Head. The side-by-side spec sheet is filled with farcical numbers. For the ZL1, that's a 6.2-liter V8 with 580 horsepower, 556 pound-feet of torque, a 4,051-pound curb weight, 0-to-60 miles per hour in 3.9 seconds, a quarter-mile time of 12.2 seconds and a base price of just $57,800. Opposing that, the Hellcat wrings out its 6.2-liter V8 for 707 hp, 650 lb-ft of torque, weighs 4,449 pounds, does the quarter in 11.7 seconds and has a base price of just $60,990. Except in the case of the Hellcat, when Motor Trend put it on the dyno the machine spit out a reading of 672 hp and 606 lb-ft at the wheels. If there's a 10-percent driveline loss through those beefed-up internals and heavy-duty eight-speed transmission, that means the Hellcat is actually rated at about 750 horsepower and 700 lb-ft. But once they get put on a closed-off strip of coast road in Northern California, there are only a few strands of hair between their respective performances. That's not the case for they sensations provide; host Jonny Lieberman calls one of them, "One of the most incredible cars ever made," and says, "It changes everything." Watch the video above to see who got the verdict and how. Related Video:

GM cutting production at two plants

General Motors is continuing to adjust to excess supply of some of its brands' models. To get production more in line with the vehicles' actual demand, the automotive giant is idling two of its factories in North America in the coming months. The Orion Assembly plant is going to be down from March 9-13, according to an anonymous plant worker and another insider speaking to Automotive News. The factory builds the Chevrolet Sonic and Buick Verano, but there are plenty of both models sitting on dealer lots, including 216 days worth of Sonics, according to AN. The factory already had two idle periods announced to reduce the excess. In addition, downtime is scheduled at GM's "Flex" line at the Oshawa, Ontario, Canada, plant from April 13-17. This affects supply of the Chevrolet Camaro, Impala, Buick Regal and Cadillac XTS. Among them, the automotive giant has the largest supply of Regals ready for dealers with 213 days worth of them, according to AN. The future for the whole Oshawa factory is cloudy in general, though. There are rumors that it could close entirely in the future because the Camaro is leaving and the Regal and XTS might not last much longer than 2017. The Canadian government and the labor union there intend to put up a fight, though.

Pony-car sales war: Mustang vs. Camaro vs. Challenger [UPDATE]

Update: An earlier version of this story misstated the 2015 Mustang's weight when compared with previous models. Additionally, we have added comments from Chevrolet in the text. The Ford Mustang has blown past the Chevy Camaro as America's best-selling pony car, and in June, it wasn't even close. The 'Stang outsold the Camaro 11,719 to 8,611 cars. The Camaro remained ahead of the Dodge Challenger, which sold 6,845 units. Even though the Camaro did post an 11.5-percent sales improvement in June, the competition is arguably stronger than at anytime since the 1970s muscle-car era. The Mustang's sales leapt a whopping 53.6 percent, while the Challenger saw a gain of 56 percent. Several factors are weighing down Camaro sales, including its lame duck status. Chevy is launching a new generation of the Camaro this year that's more than 200 pounds lighter, offers a new turbo four-cylinder engine option, and has a nicer interior than the outgoing model. Put simply: wait a few months and you can get a better car. It's also unlikely Chevy will jack up the price much, as it's historically kept the Camaro within reach of everyday enthusiasts. While Chevy fans wait in anticipation for their new sports car, Ford and Dodge have downshifted. The new Mustang, which went on sale last year, is faster and more sophisticated than its predecessor. It also offers a 2.3-liter EcoBoost four-cylinder, which Ford has credited for the Mustang's recent uptick and makes up 36 percent of the car's sales, Ford analyst Erich Merkle said. View 17 Photos June's performance allowed the Mustang to widen its sales gap with the Camaro this year. Through the first five months, Ford sold 68,290 Mustangs, a 54.4-percent increased compared with 2014. Chevy sold 42,593 Camaros, an 8.7-percent decrease. The Challenger – long the No. 3 pony car in sales volume – has seen its sales surge 41 percent this year to 37,011 units. Spokesman Monte Doran said Chevy expected that 2015 would be a "relatively soft year" for the Camaro. "Mustang is taking advantage of years' worth of pent-up demand for an independent rear suspension," he said. "When Camaro introduced an IRS, in 2009, it helped make us the best-selling performance car in America.
