The verdict

What's good

Fabric roof stows faster than most competitors and handles daily use well
Steering feel communicates road texture better than most modern roadsters
Shared platform with GR Supra means well-sorted chassis dynamics
Interior quality punches above the entry price with genuine metal and leather

What's not

Trunk shrinks dramatically with roof lowered, limiting weekend trip viability
Wind buffeting at highway speeds intrudes even with wind deflector fitted
No manual gearbox option removes a key engagement tool for enthusiasts
Infotainment screen angle creates glare issues in bright afternoon sunlight

The engine

B48

2.0L Turbo I4

BMW's B48 turbo-four is smooth and eager, its twin-scroll turbo and direct injection giving a flat, torquey midrange that punches well above the 2.0-liter displacement.

It's a pillar of BMW's modular engine family, built around a shared ~500cc-per-cylinder architecture so the four, the three-cylinder, and the straight-six all use common parts.

Each cylinder displaces almost exactly 500cc — a B48 four is essentially a B58 six with two cylinders removed.
It has landed on Wards 10 Best Engines list repeatedly since its debut.
