First introduced in 2004, the 1 Series is BMW’s answer to premium hatchback rivals from Audi and Mercedes. Traditionally it upheld BMW’s driver-focused ethos, with rear-wheel drive and a sporty driving experience. In its third generation, this all-new model radically changed the 1 Series recipe in the quest for greater practicality and everyday usability. Has it succeeded?

How we test cars

Cabin layout

How we test ease of driving

To find out how easy a car is to drive, we assess cars across a number of areas from visibility and handling to the layout of the cabin and how smoothly the engine delivers its power.

Performance

Overall
In-gear acceleration
Brakes

How we test performance

We test braking distances and whether the effectivess of the brakes fade with repeat use. Performanc is based on in-gear acceleration.

Comfort and practicality

Overall
Entry and exit
Seat comfort
Ride quality
Quietness
Seat space
Boot space (small SUVs and medium cars)

How we test comfort and practicality

Comfort and practicality includes how easy it is, or not, to get in and out of the car and the maximum height of occupants. We also measure road, wind and engine noise and assess how well the car deals with bumps from large potholes to jittery surfaces like cobble stones.

Euro NCAP

How we test euro ncap

Any car that receives a rating of two stars or less from Euro NCAP is made a Don't Buy. Any car that receives three stars can't be a Best Buy. If a car has been available for more than four years and has not been tested by Euro NCAP, it cannot be a Best Buy.

Safety kit

How we test safety kit

We factor in the safety equipment that’s factory-fitted or optional, along with how well the car protects its occupants and pedestrians in the event of an accident. We also test how easy it is to fit a variety of child car seats.

Model reliability 0-4 years

Overall
Petrol reliability
Diesel reliability

How we test model reliability 0-4 years

How reliable this car is, based on the real life feedback of current owners as collected in our annual Which? car survey. We divide all reliability feedback into three age groups: cars aged up to four years, five to nine years, and 10 to 15 years. A car cannot be a Best Buy if: It's available to buy new and has a 0-4-year model reliability score of two stars or less; or it's only available on the used market and has a 5-9-year model reliability score of two stars or less; or it's only available on the used market and launched less than five years ago and has a 0-4-year model reliability score of two stars of less.
