Dixon was talking after a two-day check at Sebring, during which the two.2-litre, twin-turbocharged V6 engines had been paired with the widespread hybrid elements in full regeneration mode for the primary time.
The Kiwi drove the Chip Ganassi Racing-run Honda check automotive, whereas Will Power dealt with the Workforce Penske-fielded Chevrolet model. Each drivers recorded over 800 laps, and roughly 1,400 miles, between them across the eight-turn, 1.7-mile quick course at Sebring.
“It is going to change the technique, particularly if it’s important to regen and also you’re being attacked and it’s going to be exhausting to regen,” Dixon instructed IndyCar.com. “It’s going so as to add a unique dynamic.
“Not solely from a technique [standpoint] however for the individual within the seat. It’s a must to be considering fairly shortly and making the proper determination on the proper time, which can make the racing much more spicy, which shall be fairly cool.”
Deployment of additional horsepower, which can substitute the present push-to-pass overtake system, will come from the hybrid utilizing electrical energy regenerated beneath braking. Guide and computerized regeneration methods had been examined, and the supercapacitor system will present as much as a further 150 horsepower.
“I’m at all times excited to strive one thing new,” stated Energy. “I’ve been an enormous a part of the testing of the brand new hybrid, working on the Indianapolis Motor Speedway street course with out regeneration energy like we’re working right here.
“It’s going very easily. We’ve had no points, and now we’ve added the regen to the ability aspect of it. Every thing goes because the engineers anticipated.”
The inner combustion engine aspect is unchanged for 2024, after the plan to change to 2.4-litre motors was shelved. The hybrid unit – which is a collaborative effort between Chevrolet and Honda – is sufficiently small to suit contained in the bell housing.

“For each producers – I do know for Honda – it’s an enormous push to be relative to what they produce of their street automobiles,” added Dixon. “This may herald new expertise that may trickle down.
“A lot lighter, compact models, which shall be higher for the long run. It’s all about effectivity, to have much less emissions and make it higher for street automobiles.”
Testing of the brand new system will proceed all through the autumn and winter, forward of its race debut firstly of the 2024 season.
This may embrace oval testing, which is the larger unknown given the shortage of braking to regenerate the ability – though it has been recommended that this may be achieved by way of slipstreaming.
“Loads of issues to be determined, however finally you’ll be able to have extra energy all the time, which might be good,” Energy stated. “All of us love extra horsepower. I believe you need essentially the most regen which you can have and use the engine to its max. It’s thrilling.”
