In today’s realities, the ideal economy car is a fully electric or hybrid vehicle, with a reduced fuel consumption not exceeding 3.6 liters per 100 km. Separately, we note that all economical cars with ICE are equipped exclusively with mechanical gearboxes, and their engine capacity does not exceed 0.9 liters (excluding SUVs). Efficiency and environmental friendliness are equally important for most consumers, so, without exception, automakers are eager to show their best achievements to potential customers.
The most economical and environmentally friendly car
On the American continent, the electric car BMW i3 became the finalist of the competition for the title of the greenest car. It is very important that it is represented in all the dealer’s dealer centers without exception. Its cost ranges from $ 31,000 to $ 52,000, and the guaranteed range from one charging is 81 miles. Up to 100 km / h, it accelerates in 7.2 seconds. It is interesting to modify this four-door hatchback BMW i3 Range Extender, which allows you to recharge the battery while driving from a gasoline engine consuming 0.5 l / h.
Official record of economy of serial cars
Record economy was demonstrated on the Spanish track Almeria circuit in the presence of representatives of the control organization from France UTAC serial Peugeot 308. His three-cylinder turbocharged petrol engine Pure Tech paired with a six-speed gearbox burned a full tank of fuel (51.4 liters) for 32 hours. The car was stopped only to replace drivers. Now the most economical cars with internal combustion engines have an official leader.
In a mixed mode of movement, the gasoline consumption was 4.6 l / 100 km, with a release of 107 g of CO2 per kilometer. The engine is equipped with a double injection system under pressure of 200 bar and a turbocharger. For the diesel version of the Peugeot 308 with the Blue HDi engine, fuel consumption was 3.1 l / 100 km, and CO2 emissions – 82 g / km.
Leader among SUVs
At its core, off-road vehicles are designed for high traffic in the most difficult conditions, not fuel economy. Nevertheless, the hybrid Mitsubishi Outlander PHEV 2015, at a price comparable with its diesel analog, is able to pass on one battery charge of 50 km. The battery can be charged from the household network or from a gasoline generator consuming 1.6 l / 100 km.
Separately, we should note an interesting solution used in the off-road car Ford Escape Hybrid. When driving at speeds of up to 40 km / h, the wheels are driven by a three-phase synchronous electric motor with a power of 94 hp, and then a 2.3-liter petrol engine comes into play. Both power units can work together or separately, which ensured a flow rate of up to 7.8 l / 100 km.
If we talk about the record in the field of economy, then they certainly are the participants of the competition SAE Supermileage, where student engineering teams compete in the construction of experimental cars. For example, this year a super-economical Canadian carshowed a consumption of 0.11 liters per 100 km. At the heart of the car is a one-cylinder four-stroke engine, running on vegetable isooctane fuel.
Ways to further improve the economy
The efforts of developers not only of engines but also of special tires with minimal rolling resistance and bodies with ideal aerodynamics are aimed at increasing the economy. In no small measure to reduce fuel consumption will help maximize the use of non-metallic parts to reduce the overall weight of the car.
