Common Questions

Find answers to common questions about torque specifications

Q1

What type of drivetrain does the 2014-Present BMW i3 use?

The BMW i3 uses a single-speed fixed gear reduction transmission, which is technically a none-transmission system. It operates with an electric motor directly driving the rear wheels, eliminating the need for a traditional multi-speed transmission. The gear ratio is 9.665:1, optimized for electric motor efficiency and performance.

Q2

What is the maximum torque output of the BMW i3's electric motor?

The BMW i3's electric motor delivers a maximum torque of 184 lb-ft (250 Nm) at 0 RPM, providing instant acceleration. This torque is managed by the single-speed fixed gear reduction system, ensuring smooth power delivery without the need for gear shifts.

Q3

How does the BMW i3's none-transmission system affect driving dynamics?

The none-transmission system in the BMW i3 provides seamless acceleration due to the absence of gear shifts. The single-speed fixed gear reduction ensures consistent power delivery, enhancing driving smoothness and responsiveness. The system is designed to maximize efficiency and performance in urban and suburban driving conditions.

Q4

What is the efficiency of the BMW i3's none-transmission system?

The BMW i3's none-transmission system is highly efficient, with an energy consumption rating of approximately 27 kWh/100 miles (16.8 kWh/100 km) for the base model. The single-speed fixed gear reduction minimizes energy losses typically associated with multi-speed transmissions, contributing to the vehicle's overall efficiency.

Q5

Can the BMW i3's none-transmission system be serviced or repaired?

The none-transmission system in the BMW i3 is designed for minimal maintenance. However, if issues arise, it should only be serviced by certified BMW technicians. The system includes sealed components that require specialized tools and knowledge for repair or replacement. Unauthorized servicing may void the vehicle's warranty.
