To make the body produce adrenaline, people usually must kick a cop in the chin, juggle soldering irons, or trap wild animals underneath wet newspaper. Today's Groupon gives you a more comfortable way to excite your cellular infrastructure: a Mario Andretti Racing Experience at Charlotte Motor Speedway. Choose one of the following options:

• For $64, you get a three-lap ride along in a two-seat, Indy-style racecar (up to a $129.99 value).
• For $182, you get the Mario Andretti Practice Drive Experience (up to a $329.99 value) with driver's fee (a $35 value). You must be at least 18 years old and have a valid driver’s license to drive.

Available dates include June 11, June 18, July 15, August 12, September 9, and October 22.

Mario Andretti Racing Experience gives racing aficionados the opportunity to motion-blur their way around Charlotte Motor Speedway, one of the sport’s most hallowed tracks and the home of the Coca-Cola 600, the Bank of America 500, and the NASCAR Sprint All-Star Race. During the practice racing experience, you’ll strap into an open-cockpit Indy Car. After receiving handy training from your crew chief, amateur need-for-speeders get a five-minute racing session motoring around the 1.5-mile track. Along the way, your crew chief will give you tips for smoother driving, such as “Steadily accelerate as you come off this turn” and “Watch out—penguins on the loose in turn four.”

If racing at insanely high speeds reminds you too much of the car chase you take to work every morning, you also have the option of riding with a professional racing instructor inside in a two-seat, Indy-style racecar, which will cruise around the superspeedway’s track for three exhilarating laps and blow past the start/finish line at the speed of a turbo-motorized puma.

Though Mario Andretti Practice Drive Experience sometimes features a discounted price online, this Groupon still offers the best deal available.
