Following successful initial collaborations that began in 2024, Driver-in-the-Loop (DIL) simulator specialist
Ansible Motion is expanding its partnership with
IAAPS Ltd, a world-class research and engineering organisation that designs, develops and tests future propulsion systems, technologies and advanced validation methods for the global automotive, aerospace and marine industries.
DIL is a simulation method where a real person acts as the driver inside a virtual environment, using a simulator that includes a vehicle's real-time computer model, steering wheel, pedals, and often a motion platform.
The new agreement centres on a long-term installation of an Ansible Motion’s Delta S2 DIL simulator based at the IAAPS research facility based on the Bristol and Bath Science Park, to create a new Vehicle-in-the-Loop (VIL) development validation environment. Building on a technical cooperation agreement with Ansible Motion that began in 2024, this second phase, set to be operational from February 2026, supports the development of advanced powertrain methodologies.
By directly connecting the Delta S2 DIL simulator to one of IAAPS’ existing AVL 1800kW full four-wheel-drive powertrain dynamometers, it will create a unique Vehicle-in-the-Loop / Driver-in-the-Loop (VIL-DIL) environment that bridges the virtual and physical world for more accurate and sustainable vehicle development of ICE, hybrid and electric powertrains.
Seamless, real-time interactionIAAPS’s new ‘state of the art’ laboratory will integrate a Driver-in-the-Loop (DIL) simulator with a full powertrain dynamometer, enabling seamless, real-time interaction between human drivers and actual powertrain systems. This allows engineers, researchers and drivers to experience realistic vehicle dynamics while the dynamometer precisely controls and monitors powertrain inputs and outputs within a controlled lab environment. A key benefit of this configuration is the ability to capture human-in-the-loop behaviour during active powertrain operation — without subjecting personnel or hardware to undue risk when replicating complex or hazardous driving scenarios.
This capability will accelerate driveline calibration and validation across a broad spectrum of powertrain systems including internal combustion engines (ICE), hybrid and battery-electric platforms, even ahead of full vehicle availability. Additionally, it enables early-stage evaluation of Advanced Driver Assistance Systems (ADAS), autonomous driving transitions and edge-case scenarios in a repeatable, resource-conscious and environmentally responsible manner.
Dan Clark, Ansible Motion’s managing director, said: “This next stage of collaboration provides IAAPS, its partners and the wider UK automotive industry with access to a world-class simulator environment that advances research methods for all forms of powertrain in controlled and repeatable lab conditions. The project also highlights our shared ambition to advance validation and testing techniques for increasingly complex vehicle powertrains.”
The Delta S2 DIL simulator was selected by IAAPS due to its ability to deliver immersive, high fidelity dynamics within a relatively compact physical footprint with minimal facilities impact – which makes it ideal for the intended powertrain research applications. The Delta S2 features a patented, six-degrees-of-freedom Stratiform motion base, immersive projection-based vision system, interchangeable cockpit and advanced control and computational systems that integrate seamlessly with the IAAPS powertrain dynos. Ansible Motion will also provide an inclusive support and maintenance package to meet IAAPS’s advanced research needs.
Milestone momentProfessor Rob Oliver, managing director at IAAPS, added: “We are delighted to announce the deepening of our collaboration with Ansible Motion, a global leader in driving simulator technology. This partnership represents a powerful alignment of capabilities, combining IAAPS’s cutting-edge propulsion system engineering and research expertise with Ansible Motion’s advanced simulation systems. This is a milestone moment for both organisations and a testament to our shared commitment to innovation.”
Under the new agreement with IAAPS, Ansible Motion will also have scheduled access to the simulator lab and IAAPS’s wider research ecosystem for internal R&D purposes, customer demonstrations and professional driver evaluations. In addition, Ansible Motion will set up a dedicated office space for four people within the IAAPS facility.
