Thatcham Research and Euro NCAP have assessed the latest driver assistance systems to ensure users are fully aware of their capabilities.

Reports of accidents where drivers have misused these systems are becoming a regular topic for the media and these new gradings are designed to inform drivers of the performance, and most importantly, the limitations of Assisted Driving systems.

“The systems that are currently allowed on our roads are there to assist the driver – but do not replace them,” said Matthew Avery, Thatcham’s director of research. “Unfortunately, there are motorists that believe they can purchase a self-driving car today. This is a dangerous misconception that sees too much control handed to vehicles that are not ready to cope with all situations. 

“Clarity is therefore required to make sure drivers understand the capability and performance of current assisted systems. It's crucial today’s technology is adopted safely before we take the next step on the road to automation. There are safety and insurance implications that must be considered seriously.” 

Ten vehicles have been initially assessed, including the Tesla Model 3, BMW 3 Series and Mercedes GLE.

The testing looked at how effective the systems control the car, how the carmaker communicates the capability and functionality of the systems and how well the car protects the driver in an emergency.

Mercedes scored the highest number of points across the three categories, with its GLE model receiving a ‘very good’ rating. The BMW 3 Series and Audi Q8 also scored top marks.

The Ford Kuga’s results showed a ‘good’ grading is possible for a mid-class vehicle, thanks to its combination of Vehicle Assistance and Safety Back-up. The entry-level Renault Clio and Peugeot 2008 offer effective systems, but lack emergency assist capability which would have boosted their grading. 

The Tesla Model 3 was top scorer in the vehicle assistance and safety back-up assessments, but was the lowest scorer for driver engagement, resulting in a ‘moderate’ grading. 

"The first batch of results show some car makers have developed robust assisted driving systems and that’s good to see. But there are also significant gaps in capability on other vehicles,” Avery explained.  

“The Tesla Model 3 was the best for vehicle assistance and safety back-up. But lost ground for over selling what its ‘Autopilot’ system is capable of, while actively discouraging drivers from engaging when behind the wheel. 

“Tesla should however be recognised for its ability to update vehicles ‘Over the Air’. Two years ago, it’s safety back up results would not have been market leading. This unique capability has seen it move the safety game on, across its whole fleet of vehicles.”

Assisted Driving Systems test results: 

Position	Car	Vehicle Assistance	Driver Engagement	Safety Back-up	Rating
1	Mercedes GLE	86	85	89	174 / very good
2	BMW 3-Series	82	83	90	172 / very good
3	Audi Q8	83	78	84	162 / very good
4	Ford Kuga	66	73	86	152 / good
5	VW Passat	76	79	61	137 / moderate
6	Tesla Model 3	87	36	95	131 / moderate
7	Nissan Juke	52	70	72	124 / moderate
8	Volvo V60	71	78	49	120 / moderate
9	Renault Clio	62	69	43	105 / entry
10	Peugeot 2008	61	74	40	101 / entry

 

Martin Milliner, claims director at Liverpool Victoria General Insurance, said: “Assisted driving systems are not all the same and whilst they are becoming commonplace in new vehicles, they are still at an embryonic stage in terms of driver awareness and understanding. The new independent grading system from Thatcham and Euro NCAP will bust the myths around driverless cars and give UK drivers a lens through which to make informed car buying choices; hopefully leading to fewer accidents and deaths on our roads.”
