New digital model of Mcity in Michigan will significantly accelerate autonomous vehicle development
Simulation software specialist, rFpro, has created a highly accurate digital twin of Mcity, a purpose-built facility at the University of Michigan for testing connected and automated vehicles and technologies under controlled, realistic conditions. The digital twin enables vehicle manufacturers and technology suppliers to accelerate development using simulation.
Highly accurate correlation
rFpro will partner with London’s Smart Mobility Living Lab to deploy an enhanced digital twin of its test network, allowing more advanced simulation of real-world testing
UK-based driving simulation company, rFpro, has partnered with London’s Smart Mobility Living Lab (SMLL) with the aim of developing an advanced digital twin of its urban testbed for Connected and Autonomous Vehicles (CAVs). The new digital twin will capture all the elements of the test environment with unprecedented realism and enable vehicle manufacturers and technology suppliers to accelerate the development of CAVs.
An accurate digital twin allows simulated tests to be carried out that correlate with real-world experiments, greatly increasing the rate at which testing is possible, and enabling customers to prepare more fully and effectively in advance of physical testing. Tests in the real-world environment can be used to validate the simulated tests, ensuring they are highly accurate and reliable.
“Digital twins help vehicle manufacturers to significantly accelerate the development of CAVs, saving time and cost, because virtual testing is so much more productive than physical testing,” explains Matt Daley, rFpro’s Managing Director. “Testing in a virtual environment is the only cost-effective way to introduce self-learning systems to the limitless number of scenarios that can occur in the real world. Most AI systems learn by experience, but training using only real-road data is too slow.”
The SMLL’s existing digital twin has already introduced a number of users to the benefits of CAV simulation. rFpro’s advanced digital twin will extend these benefits by significantly improving the fidelity of the simulated environment. These enhanced features will include a vehicle dynamics grade road surface, accurate material definitions and the highest accuracy virtual sensor models.
The routes within SMLL provide a comprehensive set of features representing most real-world urban situations typical in London and the UK, including complex intersections, roundabouts, bus lanes and other shared mobility spaces for numerous vehicle types and road users. TRL’s heritage in safety, risk assessment and regulation within the mobility sector enabled the SMLL to select these features based on their suitability for CAV manufacturers and tier 1 suppliers to test and verify their systems as fully capable for UK urban operation.
The SMLL, part of a wider network of facilities within the UK called CAM testbed UK, is unique among facility providers in that, with support from Cisco, it has one of the most advanced real-time, real-world monitoring systems in the public domain. Data collected at the roadside locations can be used to enrich the accuracy of the simulation by feeding in real-world scenarios and local traffic behaviours and also validated by supporting physical testing at the same locations.
TRL’s experience with simulating scenarios using detailed real-world incident data enables the SMLL to support the full testing cycle from safety case development through to real-world validation of vehicle behaviour. This includes not only the vehicle’s reaction to the physical road layout and surface but also the scenarios generated from interactions with pedestrians, buses, cyclists and other traffic.
“Simulation is a critical part of the vehicle development process and is key to getting CAVs on to our roads safely,” said Richard Cuerden, TRL Academy Director. “The SMLL is already the world’s most advanced urban test facility for CAVs but we believe the addition of rFpro’s advanced digital twin will offer significant additional value to our customers.”
rFpro has an ever-growing library of more than 100 locations of highly accurate digital twins from around the world. It includes public road routes, proving grounds, test facilities and race tracks.

MAHLE Powertrain’s latest development of its passive MAHLE Jet Ignition (MJI) technology can now be easily added into existing engine designs with only minimal changes to the final machining process. Continued work throughout the lockdown period means that passive MJI can now be installed as a press-in unit into engines utilising an M12 sparkplug, or larger.
“As the automotive industry seeks ways to unlock incremental efficiency and performance benefits from the internal combustion engine, jet – or pre-chamber – ignition technology is rising to the fore,” explains MAHLE Powertrain’s head of new technology and data management, Adrian Cooper. “We are beginning to see jet ignition being adopted into high-end production powertrains, such as Maserati’s recent Nettuno V6.”
MAHLE Powertrain has over 10 years’ experience developing its novel MJI pre-chamber ignition technology, which enables a highly efficient combustion process using either a passive or active system, suitable for use with either port or direct fuel injection systems. “We have worked with manufacturers and pinnacle motorsport such as F1 on the integration of this technology for close to ten years,” says Cooper. “However, our recent work on passive MJI makes the technology more accessible for adoption by mass-produced engines even as a retro-fit to existing designs, as part of a highly efficient powertrain.”
The passive MJI system features a small pre-chamber, which when ignited discharges extremely fast-moving, heated jets through a series of nozzles. This provides multiple ignition sites within the main combustion chamber, which leads to rapid, highly stable combustion and significantly improved knock mitigation characteristics. This enables the use of a higher compression ratio and in testing, up to a 10% reduction in fuel consumption has been measured.
“We have also used the opportunity during the pandemic to further develop the cold-start and emissions performance,” continues Cooper. “Through careful development, we’ve been able to engineer a system that operates under these conditions without requiring a second ignition source, enabling the system to be applied to existing cylinder heads without the requirement for costly re-engineering. We have adapted an MJI-equipped production engine to start, run and perform reliably at -8 degrees C with equivalent catalyst light-off capability to conventional spark ignition. This is very encouraging, and we’ll be continuing development to lower this figure substantially.”
Cooper stresses that the key to maximising the benefits of MJI is to understand the vehicle manufacturer’s requirements and develop the correct combustion strategy accordingly. “Our experience of integrating these systems means we can tailor MJI to many different applications, from low cost hybrid ICE to down-sized, high specific power engines or even to heavy-duty gas engines. While the engineering effort to integrate the MJI system has been simplified, other engine systems need to be further optimised in order to gain the largest benefits, which might include higher compression ratio, revised inlet camshaft profile and re-matching of the boosting system. A whole system engineering approach is the way to get the best from MJI.”
MAHLE Powertrain is now working on the development of a demonstrator engine to showcase the technology’s potential in applications between 80kW to 120kW.

- 3 Comments on MAHLE pushes ahead with future technologies
From now on, MAHLE will focus even more strongly on its strategic future priorities. The Stuttgart-based technology group is therefore maintaining its investments in research and development at a high level despite the crisis. MAHLE will further strengthen its research and development activities by expanding its global competence centers, including those in Germany and China. The key development areas are battery systems and hydrogen applications—for which MAHLE already supplies numerous innovations. MAHLE has recently begun to install hydrogen testing infrastructure at its headquarters in Stuttgart. MAHLE CEO Jörg Stratmann has weighed in to the topical debate on how to achieve the climate targets, advocating an approach that is open to all technologies: “We must tackle the climate targets using effective technologies and all the solutions currently available to us.”
“Viewed from an international perspective, there will not be one single powertrain of the future. That’s why MAHLE is continuing to follow its dual strategy: electrification, development of the fuel cell, and the use of hydrogen and alternative fuels in an intelligently electrified combustion engine,” said Dr. Jörg Stratmann, Chairman of the MAHLE Management Board and CEO at a press conference in Stuttgart on Friday. “At the moment, the change in powertrain technologies is driven primarily by political objectives. The current one-dimensional debate focused on a single drive is not productive. We want a dialog that has a basis in technology.”
As part of the expansion of its global R&D infrastructure, the group has recently set up a new competence center for mechatronics in Kornwestheim, near Stuttgart. In the future, all international activities in this field will be coordinated from this location. In Fellbach, also near Stuttgart, a new, ultramodern test bench for electric drives has been commissioned, which is one of very few of its kind in Germany. An e-mobility development center in Suzhou/China is scheduled for completion in December. MAHLE will pool its expertise in mechatronics, thermal management, and fluid management at the site and work on solutions specifically for the Chinese market.
MAHLE sees the use of hydrogen as key when it comes to shaping carbon-neutral mobility—both in fuel cell technology and in the combustion engine. Through policy initiatives and a highly diverse range of collaboration agreements in the industrial sector, the group is working hard to accelerate the establishment of these technologies. At MAHLE, research and development activities relating to hydrogen are pooled in a project house.
At the press conference, MAHLE’s Head of Corporate Research and Advanced Engineering, Dr. Martin Berger, presented a current project involving a type IV hydrogen tank. The design consists of a liner made of plastic and an outer casing made of carbon fiber. MAHLE is working on the development of a new production process for this tank that will increase its hydrogen storage density and make it cheaper at the same time. The group is also installing hydrogen infrastructure to test fuel cells and hydrogen-powered combustion engines.
To accelerate the market penetration of battery electric mobility, MAHLE is working intently on the subject of battery cooling. To allow for fast charging, the temperature in the battery cell needs to be evenly distributed and must not rise too high. On this point, Martin Berger gave an insight into another of MAHLE’s new developments—by harnessing the concept of immersion cooling, charging times can be reduced and batteries made smaller. He commented that: “Immersion cooling paves the way for a whole new generation of battery systems. With this technology, electric vehicles will be cheaper, lighter, and more resource-efficient.”

• Use of recycled ‘green’ parts cuts force’s vehicle downtime
• Savings of £45k per year achieved, thanks to MyGreenFleet parts supply
• Cash saving and operational benefits boost force in its fight against crime
South Wales Police Force is saving £45,000 a year on fleet maintenance and has drastically cut its vehicle downtime thanks to the use of green parts supplied by SYNETIQ.
The adoption of the ‘green’ policy’ has given the force a welcome cash boost, and also helped it to maximise operational capabilities for its fleet of patrol vehicles.
As a major client of MyGreenFleet since 2017, the use of green parts has become the mainstay of South Wales Police Force’s maintenance strategy.
The use of green vehicle parts supplied by MyGreenFleet – a supply portal operated by SYNETIQ, the largest salvage and vehicle recycling company in the UK – has also reduced the environmental impact of its fleet of more than 1,200 vehicles. South Wales Police no longer rely on new, manufactured replacement parts and body panels that have a higher carbon footprint than green parts.
Because it is often quicker to use green parts, the force was also able to cut the amount of time its vehicles were off the road because delivery times are much quicker than those of new parts.
As the largest police force in Wales, which serves an area of 1,250 square miles via a fleet of 850 dedicated police vehicles, South Wales Police has a clear need to maintain the frontline availability of these vehicles for its officers and keep the downtime to a minimum.
Before the introduction of SYNETIQ MyGreenFleet to the force, a lack of rapidly available parts would sometimes see parts temporarily harvested from vehicles to keep other vehicles on the road. Now, thanks to the availability of next-day-delivery green parts, that is no longer necessary – vehicles are back on the road quickly, allowing officers to continue serving the population of South Wales.
The data generated by the MyGreenFleet portal is used by SYNETIQ to identify the most common replacement parts, so MyGreenFleet can ensure good availability all year round.
With the immediate supply of popular items such as door mirrors, replacements can be delivered within 24 hours, and vehicles can return to frontline use.
