BMW and Audi Drivers Score Worst for Dangerous Braking, Data Shows

Editorial Brief
At a glance: AI-assisted overview, optimised for journalists, search & news aggregators

Data from Marshmallow Car Insurance's telematics service revealed that over half of BMW and Audi drivers received 'Poor' or worse scores for harsh braking. The analysis of over 10 million trips showed BMW drivers scored poorly 55% of the time, while Audi drivers scored 54%, both higher than the average of 51% across all drivers. This matters as it highlights potential safety concerns and the impact of driver distraction on braking behaviour.

EDITORIAL INSIGHT: Context, industry insight and market perspectives of this news story

The latest data from Marshmallow Car Insurance offers a detailed look at driving habits across different car brands, with a particular focus on harsh braking behaviour. While BMW and Audi drivers recorded the highest rates of poor braking scores, the findings also point to a broader trend, with over half of all drivers analysed receiving a ‘Poor’ or worse rating for this aspect of driving. This suggests that sudden or aggressive braking is a widespread issue, not confined to any single manufacturer.

For insurers and road safety advocates, such data is increasingly relevant as telematics technology becomes more widely adopted in the UK motor insurance market. Insights into specific behaviours like harsh braking and phone use while driving can inform both policy pricing and targeted safety campaigns. For drivers, the results highlight the value of paying closer attention to anticipation and hazard awareness, especially as distraction and inattention remain key contributors to risky manoeuvres on the road.

More than half of BMW and Audi drivers scored ‘Poor’ or worse for harsh braking, according to new data from Marshmallow Car Insurance.

Marshmallow Move, the insurer’s telematics service, analysed over 10 million trips over a three-month period.

Different behaviours were scored out of 100 and grouped into six ratings: Dangerous, Very Poor, Poor, Average, Good, and Excellent.

BMW drivers scored Poor or worse 55% of the time for harsh braking. This is well below the score for speeding, where they only scored Poor or worse 20% of the time. It was also above the total average harsh braking score of 51%.

Audi drivers scored Poor or worse 54% of the time for harsh braking.

Nearly 1 in 4 (24%) BMW drivers had a “Dangerous” braking score, with only Audi having a higher percentage (25%).

Audi and BMW drivers worst for harsh braking

By vehicle make, BMW drivers recorded the lowest braking scores.

Of the 25 car manufacturers measured, BMW, Vauxhall, SEAT and Audi were the only four with an average braking rating of ‘Poor’.

The data shows that 55% of BMW drivers scored Poor or worse for harsh braking.

Toyota 48% 29% 16% 11% 7%

Stephen Hemmings, Marshmallow’s Group Product Manager for Telematics, said:

“Distraction can reduce the time drivers have to recognise and respond to changing road conditions, increasing the likelihood of sudden braking.”

“We hope these insights will encourage drivers to give the road their full attention and anticipate hazards as best as possible.”

“With Marshmallow Move, as well as getting a discount up front, drivers get insights on their driving and tips on how to improve, helping them to stay safe on the roads.”

More than half had ‘Poor’ or worse braking scores

It wasn’t just BMW drivers that scored poorly for harsh braking.

More than half (51%) of the drivers analysed received a braking rating of Poor or worse.

Drivers who use their phone more often while driving also scored lower on braking.

The worst 25% of phone users had a “Poor” braking score on average. Whereas the best 25% of phone users were rated “Good” on braking.

Notes to editors

About Marshmallow

Marshmallow Move is Marshmallow’s telematics-based car insurance product, using driving data to assess behaviours such as braking, speed and mobile phone handling. Drivers receive regular ratings designed to help them understand their driving habits and identify areas where they may be able to drive more safely. Unlike other telematics products, drivers get a discount up front on their premium, which is fixed for the year. Visit marshmallow.com/harsh-braking-report for more analysis.

About the research

Marshmallow analysed over 10 million trips with qualifying braking ratings, using a snapshot as at 30 September 2026 and the latest qualifying rating available for each policy by that date. “Poor or worse” combines the Poor band with both lower rating bands. Very Poor, where mentioned separately, refers only to that individual band. No numerical rating values are published on this page. The sample includes policies that have since lapsed. It is not a live customer count, and results should not be treated as representative of all UK drivers. Demographic and vehicle comparisons are unadjusted. Age is the policyholder’s age. Percentages were supplied rounded to one decimal place; sums and relative comparisons are therefore approximate. Relative differences are calculated as (group A proportion ÷ group B proportion − 1) × 100. For example, (57.3 ÷ 45.2 − 1) × 100 ≈ 27%.
