Tampa, Florida — Cars with amazing new ways to save you money, protect your family, and make your drive to work more fun are ready for you to see at this weekend’s Tampa Bay International Auto Show.

Let’s start with the lifesaving technology. In Mercedes’ new S550, the Collision Prevention Assist Plus system watches the road ahead of you, even if you’re not paying attention. The car itself can hit the brakes and stop if there’s an obstacle in the road at up to 65 miles an hour.

That same sedan is loaded with fun tech, too. A touchpad in the center console controls the radio; a dial can change the color of the interior lighting to a range of red, blue, and more; and the seats? Oh, the seats! They recreate a soothing hot stone massage.

Cars with amazing new ways to save you money, protect your family, and make your drive to work more fun are ready for you to see at this weekend’s Tampa Bay International Auto Show.

In BMW’s area sits their stunning i8 sports car. It looks like a rocketship, with doors that swing up overhead and air ducts molded into the side of the car that literary keep it from getting airborne.

The i8 uses 370 horsepower to scream from 0 to 60 mph in 4.2 seconds. But the most amazing number is this: it gets 75 miles per gallon. The car is a gas/electric hybrid.

At $136,000, the i8 is out of just about everyone’s price range. But BMW has already started using the fuel-efficient technologies developed for that car in its other, more affordable models.

Chevy is also showing off fuel efficiency in unexpected places. The jaw-dropping yellow Corvette Stingray in the auto show’s Chevrolet section is an American muscle car that gets 29 miles to the gallon.

Like BMW, Chevy says it’s already rolling out advancements made for the Corvette into their other trucks, cars, and SUVs.

Every 2015 Chevy — along with all GM cars in the 2015 model year — will also be rolling WiFi hotspots, where up to seven devices can connect and get a powerful signal. It’s ideal for streaming music, or for kids in the back seat with iPhones — assuming you’re not in the Corvette, which doesn’t have a back seat.

And Ford is showing off its own version of muscle: its new 2015 F-150 pickup truck. The new truck still has a steel frame underneath, but it now carries an all-aluminum body, which Ford says doubles its dent-resistance but also saves you money.

Since the truck is now 700 pounds lighter, it’s more fuel efficient. And while EPA gas mileage statistics aren’t out yet, a Ford spokesman told me they’re seeing an improvement of 5 to 20 percent in miles per gallon, compared to last year’s all-steel model.

You can see all of these vehicles and a ton more — including amazing exotic luxury cars — plus take test drives at the 2014 Tampa Bay International Auto Show at the Tampa Convention Center. The show runs from Friday through Sunday.
