The latest Balance of Performance adjustment has been announced heading into next month's 24 Hours of Le Mans.

Hypercars under the microscope | Eight illustrious manufacturers will line up in the top class at the 93rd 24 Hours of Le Mans (11-15 June 2025). One of those is Cadillac who typifies the American outlook of performance, design and technological innovation with the V-Series.R. Focus on a Hypercar with a distinct style, a unique engine and lofty ambitions.

No fewer than four Cadillac V-Series.R entries will be on the grid for the 93rd 24 Hours of Le Mans. This Hypercar is the result of a far-reaching collaboration between Cadillac Design, Cadillac Racing and chassis manufacturer Dallara. Inspired by the&nbsp;<a href="https://www.24h-lemans.com/en/news/24-hours-of-le-mans-cadillac-shows-off-new-hypercar-56383" target="_blank">Project GTP Hypercar</a> concept unveiled in June 2022, it incorporates emblematic characteristics of the Cadillac&nbsp;<a href="https://www.cadillac.com/performance/v-series?srsltid=AfmBOoo3PxXxFtcVrgneXzdWushxkxp8cn5eTi5pawAyeDgc6-ko1u-N" target="_blank">V-Series</a>&nbsp;range, such as vertical&nbsp;lighting, floating blades and a body that is sculpted like an aerodynamic work of art.

The car&rsquo;s bodylines are the outcome of in-depth engineering work undertaken to optimise airflows with side channels guiding the air around the car. The V-Series.R is a successful union of form and function designed to perform in both the FIA World Endurance Championship and IMSA WeatherTech SportsCar Championship.

<h2>A one-of-a-kind engine</h2>

The Cadillac V-Series.R is powered by a naturally aspirated engine &ndash; the LMC55R V8 &ndash; developed from a blank page by the General Motors teams in Pontiac (Michigan). The result is a muscular V8 block that sings loud and proud and stands out from the crowd! 
Over a century of Cadillac V8 expertise has gone into building this 5.5-litre engine, comprising 1911 different parts. It also forms a structural element of the chassis guaranteeing rigidity and light weight.

The American Hypercar fielded by Hertz Team JOTA, Cadillac WTR and Cadillac Whelen also carries a standardised hybrid drivetrain&nbsp;consisting of a Bosch motor generator unit (MGU) integrated into the Xtrac gearbox, and WAE batteries. The MGU recovers kinetic energy on braking, transforms it into electricity and stores it in a battery. It then uses this electricity on accelerating to provide a power boost to the car.

<h2>V for victory</h2>

The Cadillac V-Series.R made its competitive d&eacute;but at the 2023 Rolex 24 at Daytona and has since covered over 20,000 kilometres in development, showing reliability and consistency. The car put in a fine performance at the 24 Hours of Le Mans Centenary in 2023, finishing third overall.

For this 93rd running of the French endurance classic, Cadillac is clearly gunning for its maiden outright victory in the race and, to achieve this dream, is relying on the backing of Hertz Team JOTA and their decades of technical and racing expertise.

Here are five goods reasons for following and supporting the Cadillac V-Series:

1. A naturally aspirated V8 engine&nbsp;with distinct character, the only one of its kind in the Hypercar class. 
2.A strong design combining elegance and aerodynamic efficiency. 
3. Fully mastered hybrid technology. 
4. A 100% Cadillac project from the engine to the design. 
5. A clearly defined objective: winning the 24 Hours of Le Mans.

The Cadillac V-Series.R under the microscope: ready to roar for America at Le Mans

As Porsche Penske Motorsport’s adds the finishing touches to its preparation for the 24 Hours of Le Mans next week, the German manufacturer has revealed a new model, the 963 RSP. The car is the road version of the Hypercar fielded in the FIA World Endurance Championship and the IMSA WeatherTech SportsCar Championship.

The Porsche 963 RSP is an adaptation of its racing counterpart, which has already claimedpodiums in the FIA World Endurance Championship and the North American IMSA WeatherTech SportsCar Championship. If you were in or around Le Mans today, you may have spotted the beauty gliding through villages or in the streets of the old town.

The car is the result of collaboration between Porsche Penske Motorsport, Porsche Cars North America, and Roger Penske, whose initials are included in the name. The 963 RSP is inspired by the legendary 917 that belonged to Italian aristrocrat Count Rossi &ndash; well-known to classic car enthusiasts. Derived from the model that won the 1970 24 Hours of Le Mans, the count&rsquo;s road-legal 917 was built in 1975. Registered in Switzerland, the car was regularly driven by the count, heir to Martini &amp; Rossi, of Martini Racing fame. Who has never seen that livery?

<h2>Horn and cupholder</h2>

The Porsche 963 RSP is somewhat different to its elder sister. It sports the &lsquo;Martini&rsquo; silver paint, a reworked body and a tan leather and Alcantara interior to mirror the one chosen by Count Rossi fifty years ago. 
Indicators and brake lights, a higher suspension, less extreme wet-weather tyres, a slight tweaking of the bodywork, and a horn make the model worthy of a temporary license plate from French authorities. There&rsquo;s even a detachable cupholder.

&ldquo;That was an experience that will stay with me for a lifetime,&rdquo; said Timo Bernhard, who was at the wheel of the 963 RSP for its first miles on the road. &ldquo;Driving down a public road with a 917 beside me &ndash; it felt unreal. The car behaved perfectly &ndash; it felt a little friendlier and more forgiving than the normal 963 &ndash; and felt super special and a lot more comfortable, especially as I was not needing all my safety gear.&rdquo;

The Porsche 963 RSP will be presented at the 24 Hours of Le Mans (11-15 juin 2025) before returning to Stuttgart to be displayed in the Porsche museum. In July it will head to the UK with the Porsche 917 for the Goodwood Festival of Speed.

2025 24 Hours of Le Mans Scrutineering – Friday 6 June programme

	The Endurance Committee of the FIA and the WEC issued a change to the Balance of Performance for LM GTE on May 22.&nbsp; The adjustment will slightly improve the performance of the Porsche GT3 RSR entries following an increase of restrictor diameter of 0.3 mm, representing a 2.1% increase in air to the engine.&nbsp; The Aston Martin Vantage model must carry an additional 10 kg following the latest data review which includes the strong race performance at the recent Silverstone WEC event.&nbsp;

	The Aston Martin Vantage is no longer the lightest entry in the class, with that distinction now reserved for the Porsche GT3 RSR.&nbsp; The heaviest LM-GTE entries on the grid as the cars roll for the test day at Le Mans will be the BMW Z4 and Chrysler Viper.

	No performance changes were made to the Ferrari 458 Italia following their sweep of both GTE-Pro and GTE-Am at Spa last month. &nbsp;
