Radio-controlled cars.

Radio-controlled

Radio-controlled (or R/C) cars are self-powered model cars or trucks that can be controlled from a distance using a specialized transmitter. The term "R/C" has been used to mean both "remote controlled" and "radio controlled", where "remote controlled" includes vehicles that are connected to their controller by a wire, but common use of "R/C" today usually refers to vehicles controlled by a radio-frequency link. This article focuses on radio-controlled vehicles only.

I have one of this a it is fuel powered, it is a totally new experience compared to those that are powered by batteries:

ELECTRIC VEHICLES
1/10 scale Buggies: Sleek and fast, buggies are great for racing or play. Most are two-wheel-drive (2WD), with top speeds of about 15-30 mph. For use on- or off-road.
1/10 scale Stadium trucks: Stadium trucks share much of their componentry with buggies, but are wider and can handle rougher terrain thanks to increased suspension travel. Most are two-wheel-drive (2WD), with top speeds of about 15-30 mph. For use on- or off-road.
1/10 scale Monster trucks: This popular category includes 2WD and 4WD trucks. The 2WD models are more affordable and use a single motor; the 4WD monsters use two motors for super torque and crushing power. Both have soft, long-travel suspension to soak up bumps. Top speed is about 15mph. For use on- or off-road.1/10 scale Touring cars: These are probably the most realistic electric RC cars, with bodies just like those you see on the highway everyday. Tourers are 4WD, and can go as fast as 40mph with the right motor. For use on-road only.
NITRO VEHICLES
1/10 scale Stadium trucks: Nitro stadium trucks appear identical to electric stadium trucks, but use a .12 cubic-inch displacement engine for power instead of an electric motor. They're good for racing or play, and average about 30mph for top speed. For use on- or off-road.
1/10 scale Touring cars: nitro tourers may use .12 or .15 powerplants, and can be very fast indeed—up to 55mph. As with electric tourers, nitro tourers feature 4WD and realistic body lines. For on-road use only.
1/8 scale Monster trucks: These giants feature large .21 engines that make a lot of horsepower. As a result, nitro monsters are fast (about 40mph) and can plow over or through just about anything! For use on- or off-road. 1/8 scale Buggies: Like the other 1/8 scale machines, these vehicles are powered by .21 engines. Buggies can go just about anywhere, are very tough, and top out close to 60mph. For use on- or off-road.1/8 scale On-road cars: The cutting edge of RC performance! Top speeds of the .21-powered cars approach 80mph, and shifting 2- or 3-speed transmissions are standard. Foam tires provide super grip, but wear quickly, and these machines are strictly for smooth road courses—not for the inexperienced.
 
ENGINE POWER OR ELECTRIC POWER?  RC vehicles come in all shapes and sizes, but the most basic distinction between types of RC car models is their power source. All are either powered by an electric motor and battery, or an engine that runs on fuel. Which is better for a beginner? Faster? More fun? The answers may surprise you!
 
ELECTRIC VEHICLES have the advantage of clean, quiet operation. They expel no fumes, and don't produce any significant noise. They can be operated indoors, cost less than similar engine-powered models, and are the easiest types of vehicles to get started in the hobby with. In terms of performance, electric models can have some disadvantages. Duration is limited by battery capacity, so you'll have to stop every ten minutes or so to recharge the battery pack (or install a fresh pack, if you have a few charged and ready to go). In stock form, electric vehicles are generally not as fast as similar nitro-powered machines, but it's easy to make an electric car faster with an aftermarket motor—although such a modification will also decrease battery life.
ENGINE POWERED MODELS, which are more commonly called "nitro" kits, because they run on nitro methane-based fuel (more on that later), have two primary advantages: higher speed and longer run time. It's easy to make a "pit stop" for more fuel with a nitro-powered car, and keep driving with only a moment's interruption. But remember, the on-board battery that powers the vital radio gear will eventually need a recharge, so don't go too long without stopping! Nitro cars are generally faster than similar electrics, and the realism of authentic engine sound and exhaust smoke add a gee-whiz factor that electrics can't match. But those can also be disadvantages, if you wish to operate the vehicle in an area where noise is an issue, or wish to run your car indoors—nitro-power is for the great outdoors only. Nitro cars also require more frequent maintenance, are more expensive than similar electric models, and tend to be a little messy, due to fuel and exhaust residue.
