BMW i3 Engine – Full Specifications

The i3 gets its power from a 168 hp electric motor in the standard vehicle or 181 hp in the i3. This connects to the rear axle via a single-stage gearbox with a fixed ratio and uses a liquid-cooled lithium-ion battery. The i3 has neat packing. The battery fully integrates into the rear cabin floor, whereas the engine is under the boot floor. Its powerful electric motor and carbon-fiber structure prevent the weight from inflating further.

In addition, thanks to the lightning-fast torque of the BMW i3, it accelerates quickly with the electric motor. It reaches a time of 0-62mph in 7.3 seconds. On the more powerful i3s, this drops to 6.9 seconds, while the top speed increases from 93 mph to 99 mph. The sportier i3s version has a new and more responsive traction control technology. What this means is less power waste on just spinning the wheels. The initial torque bump triggers the i3, but acceleration decreases with increasing speed.

Fuel economy and range

The US Environmental Protection Agency rated the power consumption of the BMW i3 (60 Ah) at 27 kWh / 100 mi (16.9 kWh / 100 km). This is with a combined energy consumption of 124 Miles Per Gallon of Gasoline. This is with an electric range of 81 miles. With these values, the fully electric BMW i3 is the most fuel-efficient EPA-certified BMW vehicle of all years. This is regardless of the fuel type. The REx variant of the BMW i3 has slightly lower ratings than the BMW i3 all-electric. This is because of the extra weight of the twin-cylinder gasoline engine that is used in the i3 REx. The BMW i3 REx also surpassed the other similar cars as the most efficient EPA-certified car with a gasoline engine in 2014. 

The BMW i3 engine with the 94 Ah battery has a full range of 114 miles. The combined fuel consumption of the 94 Ah i3 is 118 MPGe. Compared to 124 MPGe of the 60 Ah battery model. The BMW i3 REx with a larger battery of 94 Ah has a range of 97 miles, while the combined fuel consumption is 111 MPGe. Range with the gasoline engine also increased to 83 miles from 78 miles in the prior versions. The battery power is also increased to 120 Ah, resulting in a full capacity of 42.2kWh. The 2019 BMW i3 REx that has a 120 Ah battery has a battery-only range of 126 miles. It also has a combined gasoline and electric range of 200 miles and a combined fuel economy of 100MPGe.

How many miles can a BMW i3 go?

Well, if you combine both the engine’s ability to give mileage, the distance that a BMW i3 can reach will be around 600 km. As we have already discussed, the ability of the gasoline engine to reach the maximum distance is around 560 km. Moreover, the plug-in hybrid motor is what makes the BMW i3 Rex car different from other BMW cars.
