Performance & Drive
In town
Comfortable and refined. The i4 feels like a traditional BMW in urban environments — comfortable, well-built, and effortless.
On the motorway
Excellent. Refined cruising with proper BMW composure. The eDrive40's 365-mile range is among the best available, making long motorway journeys genuinely practical.
On a twisty road
This is where the i4 excels. It's the most driver-focused electric saloon available. The steering has weight and feedback, the chassis is balanced and responsive, and it genuinely rewards enthusiastic driving.
The M50 is properly quick — 536hp and 3.9 seconds to 62mph. The eDrive40 is the sweeter handler thanks to its rear-wheel drive layout and lighter weight.
Space & Practicality
Front seats
Excellent sports seats in a premium cabin. The interior quality is high — this feels like a proper BMW.
