Emission of Green House gases from cars is largely influenced by fuel-efficiency of the model. Besides this, the fuel price constantly fluctuates. As a result of these factors and market trend, automobile manufacturers started research & development of cars with better fuel-efficiency than ever. Some of the most fuel efficient cars are as mentioned under.
Dodge Dart Aero
This car derives its efficiency from 1.4-litre, 16-valve, Turbo MultiAir engine of Chrysler. It generates power of 160-bhp at 5,500 rpm and torque of 249 Nm at 2,500 rpm. The maximum efficiency provided by Dart Aero is 100 km per 5.7 litres or 49 miles per gallon. Besides, certain steel components have been replaced with aluminium to reduce weight, electric grille shutters are available for reduction of drag and similar features have been included to enhance the overall performance of the Dodge Dart Aero.
It is one of the best among electric vehicles with a range of 62 miles as rated by EPA. The car runs on 49kW AC Synchronous rear motor, which requires 7 hours of 240V EVSE charge. It has 88-cell, 330V, 16kWh lithium-ion battery. Mitsubishi i-MiEV has rear-wheel drive and can reach maximum speed of 130km per hour. 4-wheel ABS with EBD and BA assure that the car is considerably safe in its class. Charging docks and quick-charge ports are optionally provided with top 2 variants of the car.
Toyota Scion iQ-EV
Scion iQ-EV is available in 4 variants of petrol engine and a diesel engine too. Both the 3-cylinder, 996cc and 998cc engines generate power of 68PS at 6,000 rpm and torque of 98 Nm at 4,800 rpm. However, they differ in Carbon Dioxide emission as the former emits 101 to 112 CVT while the latter emits 99 to 110 CVT. Although both 4-cylinder engines are 1329cc, the torque generated by model 1.33 and 1.3 is 123 Nm and 118 Nm respectively at 4,400 rpm. The former emits CVT 113 to 120 while the latter emits CVT 101 to 112.
Ford has put considerable effort to maintain its competitive position among the most fuel efficient cars. The result of the continuous research and development is Ford Fiesta, which is available both as hatchback and as sedan. The standard EPA mpg ratings for Fiesta are 29 on city roads and 39 on highways. Besides, it comes with enhancement packages that can boost its efficiency up to 40 on highways.
The effort put by these automobile manufacturers and others that are not mentioned here is appreciable. Rigorous and persistent efforts from the top manufacturers can be the key to future where the most fuel efficient cars would be a norm and trend.
