Muscle cars break the 700-horsepower barrier

As if it were the 1960s all over again, Detroit automakers are pushing horsepower in what's left of their muscle car lineups to new heights.

But having just announced 700 horsepower in a production car, some experts question whether it's more power than most potential buyers can handle.

The bar was raised last week by Chrysler Group's Dodge, which announced that a special version of the Challenger will spit out 707 horsepower for the first time in a production car. Ford Motor and General Motors' Chevrolet are already within striking distance:

• Ford's 2014 Shelby GT500 version of the Mustang already gets 662 horsepower, but an all-new Mustang is on the way for 2015, and that horsepower rating could increase again.

• General Motors coaxes 580 horsepower out of big V-8 in the Camaro ZL1, and "at least" 625 out of the engine in its 2015 Corvette Z06.

The cars are a throwback to a more innocent age of cheap gas and screeching tires. Back in the 1960s and 1970s, cars like the Pontiac GTO, Plymouth Barracuda and Ford Boss 302 ruled the roads.

Prices of these new models are on the upper end of affordability for mainstream car buyers — and their appeal usually is limited to Baby Boomers, because they have both the spending power and the nostalgia. For them, allegiances can switch quickly to the most powerful car.

"It is a game of one-upsmanship," says Rik Paul, auto editor for Consumer Reports magazine. "For people who buy these cars, it's bragging rights."

But, he says, it may be way too much power if left in the hands of inexperienced drivers. For instance, he says, his magazine warns parents against letting their kids drive sports cars or those capable of excessive speeds.
