Gaydon, United Kingdom, July 27, 2022 – For the Jaguar I-TYPE 5 Formula E race car to function at its peak, it is crucial to know precisely when to employ power and when to utilize energy recovery through regenerative braking.
Races are won by efficiency. Road cars are already getting better thanks to this Jaguar racing energy technology.
Intelligent upgrades:
The Jaguar TCS Racing team developed Predictive Energy Optimisation (PEO), which improves energy efficiency in real-world driving by up to 10%*.
Ideal harmony
PEO determines the most effective way to utilise the power from the PHEVs’ electric motor and gasoline engine as it travels to maximize range and efficiency in the Jaguar F-PACE P400E and E-PACE P300E models.
Continually planning ahead:
To ensure a silent arrival and no exhaust emissions, PEO also saves at least six kilometers of electric-only range for you to use on the last leg of your journey.
Excellent timing
When approaching curves, intersections, and roundabouts, Jaguar’s Eco Coach, included in the XE, XF, E-PACE, and F-PACE MHEVs, tells drivers to accelerate to maximize energy regeneration.
Race established
Mitch Evans and Sam Bird of Jaguar TCS Racing utilise the lift and coast cycles of Eco Coach technology to optimize their energy strategy during an E-Prix.
Mitch Evans and Sam Bird of Jaguar TCS Racing are skilled judges of the greatest braking position for a corner as well as the best spot to pull off the throttle, allowing them to maximize regen and avoid wasting energy using the friction brakes.
Gaining knowledge from these tactics will directly aid Jaguar’s plug-in electric hybrids (PHEVs) and mild hybrids by increasing efficiency and lowering emissions (MHEVs).
The Jaguar TCS Racing team builds a highly accurate model of every city circuit in advance of each round of the ABB FIA Formula E World Championship, down to the drainage covers.
The model built for the London e-Prix, which will take place on July 30 and 31, also takes into account changes made for this season to the curvature of the double chicane between turns 10 and 13.
The models are used to create the energy strategies for the races in the cutting-edge driver-in-the-loop simulator.
These race-winning tactics guarantee that the drivers always apply the brakes and take off at the ideal moments, allowing them to save as much energy as they can.
Every joule of energy transferred to power the I-TYPE 5’s motor and returned to charge the battery during regenerative braking is accounted for and used as efficiently as possible thanks to this feature.
Sam and Mitch make sure they have the energy to make it to the finish line while taking full advantage of the performance required to maintain the lead.
What practical applications of Jaguar Racing Energy Technology there are
The Predictive Energy Optimisation capability for the Jaguar F-PACE P400e and E-PACE P300e PHEV vehicles was developed using software learnings from this approach.
When a location is entered into the Pivi Pro infotainment system’s navigation, PEO receives an overview of your trip (up to 650km in length), which it divides into 100-meter parts for study.
PEO makes an informed choice about which powertrain should be used at each stage, prioritizing the electric motor in urban areas to deliver zero tailpipe emissions driving, for example, or the efficient Ingenium petrol engine on motorways.
It does this by analyzing a wealth of GPS map data, including the types of roads – and average speeds on them, as well as gradients.
In real-world driving, this sophisticated, predictive regulation of the two power sources can increase energy efficiency by up to 10%*.
The system also makes sure that you have at least six kilometers of EV range available in reserve, ready to be used throughout the last leg of your journey and allowing you to arrive at your destination without making any noise or emitting any tailpipe emissions.
Eco Coach attribute
Used in the Jaguar XE, XF, E-PACE, and F-PACE MHEVs, the system reads the road ahead and tells drivers when to take off, maximizing the advantages of regenerative braking.
This helps customers develop a smoother, more efficient driving style.
The lift and coast cycles Mitch Evans and Sam Bird use to optimize energy utilization during an E-Prix are analogous to Eco Coach technology.
In Formula E, regenerate is essential since the race vehicles regenerate about a third of the energy needed to finish the 45-minute plus one-lap race distance.
Utilizing GPS technology
On the road, Eco Coach determines the most likely path the car will travel using the GPS location of the vehicle and data stored in the cloud.
The technology can look ahead for up to 2.5 km, or the so-called electronic horizon, to understand upcoming road features like corners, junctions, and roundabouts, lower speed limits, and downhill slopes—all elements that would probably cause the driver to depress the accelerator pedal.
This technology works in conjunction with map data, including gradients, road curvature, and speed limits.
This sophisticated image of the road ahead, which is updated every 10 meters, is provided to the powertrain control module to help it decide when it is best for the driver to take off, allowing as much deceleration as possible to be accomplished by regenerative braking rather than friction brakes.
When the car reaches this position, Eco Coach intuitively signals the driver to let off the gas by displaying a filled-in green pedal icon in the instrument panel.
When the driver does so, the icon transforms into an outline and vanishes when they hit the brakes.
The steering wheel light system used by race car drivers to determine when to lift and coast on the race circuit is replicated by this.
“Less than one percentage point of energy consumption per lap can mean the difference between winning and losing; therefore, any small improvement in efficiency matters.
Because of this, we meticulously model every track and the Jaguar I-performance TYPE’s on it in order to create the best energy plan for each Formula E race.

The Predictive Energy Optimisation technology in Jaguar’s plug-in hybrids is so effective because of the methods we employ and the priceless knowledge we have amassed, allowing customers to get the most out of their cutting-edge powertrains.
The Eco Coach system in Jaguar’s mild hybrid vehicles serves the similar purpose, assisting drivers in reducing pollutants and fuel consumption.
Both are excellent illustrations of our Race to Innovate philosophy and how we are imparting to our clients the lessons we have learned from the very competitive world championship motorsport.
