Summary: AB Dynamics has begun customer deliveries of the GST 120 Plus, with the first platform entering service at a major Japanese vehicle manufacturer. The deployment gives the OEM capability to run the high-speed test scenarios introduced in the latest Euro NCAP protocols. Seven further units are on delivery, including to a vehicle manufacturer in the US, a new BEV start-up and a major NCAP test laboratory in China.
Key engineering takeaway: The GST 120 Plus shares the chassis and external dimensions of the GST 120 platform but adds a 13% increase in battery capacity, the latest brushless motor technology and optimised gearing to reach test speeds of 130 km/h. ABS braking on each wheel improves stability and shortens stopping distances, which minimises the track length required for testing. The platform reaches the standard 80 km/h test speed in under 130 metres.
Why it matters: Euro NCAP’s 2026 update added more than 1,200 test scenarios, including motorway and highway cases that did not exist in the previous version of the ratings scheme. For many programmes the constraint is now test capacity rather than vehicle capability, and AB Dynamics states the GST 120 Plus is the only Euro NCAP-approved ADAS target platform capable of achieving the latest high-speed test scenarios.
- AB Dynamics begins customer deliveries of the GST™ 120 Plus, with the first going to a major Japanese vehicle manufacturer enabling high-speed ADAS testing up to 130 km/h.
- It is the first in operation with seven more on delivery to customers, including a vehicle manufacturer in the US, a new BEV start-up and a major NCAP test laboratory in China.
- The GST 120 Plus is the only Euro NCAP-approved ADAS target platform capable of achieving the latest high-speed test scenarios, providing capability to fully test and validate vehicles.
- The delivery follows the introduction of Euro NCAP’s latest high speed test scenarios adopted as part of the latest 2026 protocols.
Leading automotive test solution supplier AB Dynamics has delivered the first GST™ 120 Plus to a major Japanese vehicle manufacturer. The deployment gives the OEM capability to test and validate its vehicles against the new high-speed scenarios introduced in the latest Euro NCAP protocols.
The deployment is the first of eight GST 120 Plus platforms ordered to date. Additional units are due to enter operation in the short term, including four at vehicle manufacturers and a major NCAP test lab in China.
Why Euro NCAP’s 2026 Protocols Raised ADAS Test Speeds
Euro NCAP’s 2026 update, which was implemented in January, is the most significant change to the ratings scheme since it was introduced. It includes more than 1,200 additional test scenarios and includes new high speed test scenarios, replicating typical motorway and highway conditions where many real-world accidents occur.
We developed the GST 120 Plus with the Euro NCAP 2026 protocols in mind. The protocols have put real pressure on manufacturers’ test capability, particularly for high-speed scenarios that simply didn’t exist in the previous version of the ratings scheme. We believe this is the first ADAS test platform operating at speeds of 130 km/h to enter service with an OEM anywhere in the world. The 2026 protocols have raised the bar for the whole industry, and the early demand we’re seeing shows how fast manufacturers are moving to build this high-speed capability.

What Is The AB Dynamics GST 120 Plus?
Launched in December 2025, the GST 120 Plus is listed by Euro NCAP for approval for use in official tests. It shares the chassis and external dimensions of the GST 120 platform but introduces a 13% increase in battery capacity, the latest brushless motor technology and optimised gearing to deliver the higher test speeds the new protocols demand. Combined with ABS braking on each wheel for improved stability and shorter stopping distances, the upgrades minimise the track length required for testing, which is a key constraint at many proving grounds. The platform reaches the standard 80 km/h test speed in under 130 metres.
Test Scenario Libraries And ADAS Targets
To further help OEMs cope with the substantial rise in test scenarios under the 2026 protocols, AB Dynamics has developed a comprehensive library of pre-configured test scenarios within its track test software to automate the process of Euro NCAP ADAS testing. The Euro NCAP 2026 ‘special group’ is pre-installed on the GST 120 Plus, allowing customers to begin running the new high-speed scenarios as soon as the platform enters service.
AB Dynamics provides a complete end-to-end solution for ADAS testing, with a comprehensive range of platforms and targets covering cars, motorcycles, pedestrians and cyclists. The platforms work seamlessly with the company’s driving robots to precisely control the speed and direction of the vehicle under test, while Synchro™ software choreographs the vehicle and targets with centimetre-level accuracy.
Frequently Asked Questions
What is the AB Dynamics GST 120 Plus?
The GST 120 Plus is an ADAS target platform from AB Dynamics, launched in December 2025 and listed by Euro NCAP for approval for use in official tests. It carries soft targets such as vehicles, pedestrians and cyclists across a proving ground at controlled speed and position, and is rated for test speeds up to 130 km/h.
How does the GST 120 Plus differ from the GST 120?
It shares the chassis and external dimensions of the GST 120 but adds a 13% increase in battery capacity, the latest brushless motor technology and optimised gearing to reach the higher speeds the Euro NCAP 2026 protocols require. It also adds ABS braking on each wheel for improved stability and shorter stopping distances.
What top speed does the GST 120 Plus reach?
The platform is capable of high-speed ADAS testing up to 130 km/h. It reaches the standard 80 km/h test speed in under 130 metres, which reduces the track length required for a test run.
Why do the Euro NCAP 2026 protocols require higher test speeds?
The 2026 update, implemented in January, is the most significant change to the ratings scheme since it was introduced. It adds more than 1,200 test scenarios, including new high speed scenarios that replicate typical motorway and highway conditions where many real-world accidents occur.
Who has taken delivery of the first GST 120 Plus?
The first platform has been delivered to a major Japanese vehicle manufacturer. It is the first of eight ordered to date, with further units due to enter operation at a vehicle manufacturer in the US, a new BEV start-up and a major NCAP test laboratory in China.
