2020 BMW I3 Summary

It’s easy to forget BMW was paddling into the growing electric vehicle wave when it was only a gentle swell. It took off early with the i3 city car, which believe it or not has been in the Aussie new car market for six years.

While the German maker has long been developing the concept of electrified powertrains in existing models, the i3 was the result of a dramatically different approach, showcasing the use of exotic materials and innovative packaging.

Like its i8 supercar sibling, the i3 won’t be replaced with a new-generation version, but BMW says it will continue to develop this high-tech hatch before it departs, and we spent a week in the sporty i3s to see how it stands up in 2020.

Verdict

The updated Audi S3 Sportback is a fun-sized dynamo with impressive outputs and athletic road manners. It’s missing a few premium features, but its compact size paired with a gutsy engine makes it a compelling option for drivers who don’t want to compromise on performance (just space).

Verdict

Yes, it’s pricey for a small hatch, but this little BMW is a city car like no other. The i3s is tailor made for the urban environment, and six years on retains the quirkiness and charisma that stood it apart at launch, and it can still hold its head high among the current EV crop.
