‘Active Lean’ isn’t a diet supplement, it’s how Toyota’s i-Road electric trike gets around

Cars like the Corolla and Camry have given Toyota a reputation for conservatism. The company’s latest product may change that.

Toyota says it will put the three-wheeled, electric i-Road into production. Don’t expect to see one Stateside anytime soon, though: It will be used primarily by Toyota’s Ha:mo car-sharing service in Japan.

The i-Road was unveiled at the 2013 Geneva Motor Show, and it hasn’t gotten any less strange since.

A 2.7-horsepower electric motor and lithium-ion battery pack power the two front wheels. At around 660 pounds, it’s more like a bike than a car. Yet it has a roof and a steering wheel.

Despite its three-wheeled configuration, the i-Road can actually lean into corners like a two-wheeled bike, thanks to its nifty “Active Lean” suspension system.

The i-Road’s party piece automatically balances it during cornering, making it much easier to operate, according to Toyota.

A computer calculates the correct amount of lean based on steering angle, vehicle speed, and a gyroscopic sensor. It controls an actuator, which moves the wheels up and down accordingly.

On the more practical side, the i-Road has tandem seating for two, and gets about 31 miles of range per charge. Top speed is 28 mph and, considering that it has the frontal area of a Cobra gunship, we wouldn’t be shocked to see one illegally threading between lanes of traffic on a crowded Tokyo street.

The i-Road’s introduction will coincide with an expansion of the Ha:mo car sharing service, which has been operating in Toyota City since October 2012.

Toyota envisions Ha:mo as a prototype for a future urban transportation system that seamlessly integrates personal vehicles and public transit.

Ha:mo provides users with multi-modal routing information that accounts total carbon dioxide emissions and current traffic conditions, planning the most efficient routes possible, Toyota says.

Rivian R2 vs R1S: How will Rivian’s cheaper SUV compare?
The front three-quarter view of a 2022 Rivian against a rocky backdrop.

Rivian has finally unveiled the R2, its long-awaited attempt at a more affordable electric SUV. The new vehicle may not be available just yet, but fans of Rivian's design aesthetics and feature set are already looking forward to being able to order the new car. The R2 is targeted at being a more affordable take on the electric SUV and will sit alongside the flagship-tier R1S.

Let's get this out of the way right now: The R1S is most likely going to be a better vehicle than the R2. Rivian isn't replacing the R1S with the R2 — it's releasing the R2 as a more affordable alternative, and there will be some compromises when buying the R2 over the R1S.

We’re finally getting to the fun part of automakers’ methodical quest to replicate their lineups with electric cars.
