The Great Food Truck Race, hosted by Tyler Florence, kicks off Season 4 on August 18 at 9pm/8c with new teams who are hitting the road for the longest route in the history of the series, 4,181 miles to be exact. Much like last year, these competitors are not seasoned food truck operators; instead the teams are made up of talented cooks who have dreamed up unique food concepts and want to turn their dreams into a reality, which is to operate a food truck business.

Eight teams of three are provided with a truck for the cross-country race. Each episode will test the teams' resilience in a series of challenges and the team that has made the least in sales will be sent home packing. In the end, only one team will win the grand prize of $50,000 and the keys to their truck.

This season's teams bring unique food perspectives from across the nation. Get to know the teams here (also see the Season 4 Food Truck Teams gallery):

Aloha Plate (Los Angeles, Maui and Oahu, Hawaii): Brothers Lanai and Adam, along with their friend Shawn, are making it their goal to bring the cuisine of Hawaii to the mainland. With classic dishes such as loco moco and poke, the guys think they will make island fans out of everyone who tries their food.

Boardwalk Breakfast Empire (Sea Bright, N.J.): After losing her Jersey Shore restaurant of 37 years to the effects of Hurricane Sandy, Joanne is ready to get back to business and open her very first food truck with her two best friends by her side, Ilene and Tim, cooking up an over-the-top breakfast menu.

Bowled and Beautiful (Los Angeles): Single moms Liza, Jessica and Heather find themselves at a fork in the road, ready to take on new challenges. They believe a food truck featuring fusion California cuisine served in a bowl will be the answer to making better lives for themselves and their kids.

The Frankfoota Truck (New York): Mirlinda, Dana and Victoria are three best friends who have previously worked in restaurants, but they're tired of taking orders from bosses. They want to open a food truck featuring their childhood favorite: hot dogs with a twist, such as unique toppings.

Murphy’s Spud Truck (Los Angeles): After recovering from a health problem, Nicole decided to follow her dream and attend culinary school. With mom Suellen and brother James behind her, she wants to open an Irish-inspired food truck, featuring potatoes stuffed with all kinds of ingredients — there's even a dessert potato.

Philly’s Finest Sambonis (Philadelphia): After a car accident, former electrician Erik wants to follow his dream and cook with his best friends, Joe and Chris. The guys believe they have perfected the cheese steak and want to take their sandwiches, which they call sambonis, on the road.

The Slide Show (Los Angeles): After closing his restaurant, which left him in deep debt, Chef Das turned to teaching culinary school and made it a mission to eventually get back into business. With the help of his chef friends Ahren and Maurice, he wants to open up a food truck offering unique sliders everyone will crave.

Tikka Tikka Taco (St. Louis): Ready for a new path in life after the Army and working odd restaurant jobs, Shaun wants to go into business with his older brother Michael and their uncle Sam. Since food has always been at the center of their Indian family, a food truck offering Indian tacos seems to be the perfect idea.

This season will celebrate the country's national landmarks, starting at the Hollywood sign and ending in front of the nation's Capitol building. The trucks will start their seven-city adventure in Los Angeles, Beverly Hills and San Francisco, Calif., then move on to Portland, Ore., Pocatello, Idaho, Rapid City, S. D., Minneapolis/St. Paul and Chicago before completing the competition in the Washington, D.C. area.

Watch the season premiere on August 18 at 9pm/8c when the teams get their brand-new food trucks and begin the race. The first challenge will test the teams' ability to sell upscale versions of their signature dishes at upmarket prices.
