Designed to offer a unique driving experience, the XSeed Concept vehicle by Marcos Beltrao seats two passengers and looks to offer the high performance of a lightweight sports car. The vehicle is intended to serve as a dual-function car that is a roadster as well as a buggy. The unique combination of a buggy and a roadster allows the vehicle to offer the thrill of both and the hybrid concept can be operated with gas and ethanol as well as an electric engine.
The 1600cc four-cylinder engine that the XSeed is powered by makes it a strong proposal for the sports cars market while its low weight and innovative design ensures a stand out yet economical performance on the road. With electric thrusters on each wheel, the battery pack on the XSeed can be charged via any power outlet or even while the car is in motion which allows the vehicle to conserve fuel and extend the battery-only range. The XSeed goes from 0mph to 60mph in 4.5 seconds and the vehicle outputs 225 horsepower when both engines are in use.
Made of carbon nanotubes, the tubular structure of the vehicle’s frame allows it to maintain a relatively low weight. The ceramic compound used to fashion the engine also helps in weight savings since it is much lighter than an engine made of aluminum only. Thanks to the silicon added to the ceramic, the engine is that it requires no cooling or lubrication and lasts longer. With lubrication and cooling being redundant features, the engine also does not need to have a radiator, hoses, pipes, filters and water and oil pumps which results in further space and weight savings for the vehicle.
The ceramic compound is able to resist extreme temperatures since it has a very low thermal expansion coefficient and having all the main components of the engine fashioned from the same ceramic compound allows the powertrain to function more efficiently. MuCell technology (which is uses nitrogen or carbon dioxide during the plastic injection process) is used to manufacture all the plastic parts used in the car to ensure that the vehicle weighs 25 percent less without losing too much strength which helps the vehicle meet safety standards.
Magnesium alloy is used to fashion the swanky 22-inch alloys on the vehicle. Each wheel is also fitted with independent suspension while carbon-fiber-reinforced plastic (CFRP) is used to fashion the exterior of the vehicle to further reduce the weight of the vehicle. The vehicle has an overall weight of 760kg thanks to the strong yet extremely lightweight materials used in its creation.
