American manufacturer Cadillac has updated its hypercar for its two-pronged championship commitments in 2026.

Next season, the&nbsp;Cadillac V-Series.R&nbsp;will compete in the FIA World Endurance Championship and the IMSA WeatherTech SportsCar Championship&nbsp;with a new aero set-up. While the American hypercar retains signature design elements of the production V-Series, notable changes have been made. These include the removal of the front dive planes and winglets and a reshaped rear wing profile. The rear wing now appears to be lower as a result.

These updates are intended to boost the peak speed of the V-Series.R. At the 24 Hours of Le Mans, the quickest Cadillac V-Series.R (the Cadillac Whelen #311 car) reached&nbsp;345.6 kph. In comparison, the top speed for a Ferrari 499P was 349 kph&nbsp;(for the Ferrari AF Corse #50 car). The Hertz Team JOTA #12 Cadillac meanwhile peaked at 343.4 kph.

Three Cadillac V-Series.Rs are taking part in the IMSA WeatherTech SportsCar Championship homologation tests today and tomorrow at the Daytona International Speedway. All feature these improvements.

Cadillac Hertz Team JOTA has announced its driver line-ups for the 2026 FIA World Endurance Championship season. The American manufacturer is banking on continuity and experience.

Cadillac Hertz Team JOTA ended the 2025 season in fourth place in the FIA Hypercar World Endurance Manufacturers&rsquo; Championship. Highlights of the campaign were undoubtedly a maiden victory in the 6 Hours of S&atilde;o Paulo and three pole positions, including Hyperpole at the 93rd 24 Hours of Le Mans. The outfit is banking on two talented, experienced driver line-ups to add further wins to its tally in 2026.

Alex Lynn,&nbsp;Norman Nato&nbsp;and Will Stevens scored points in every round in 2025 and will continue to&nbsp; share the wheel of the #12 <a href="https://www.24h-lemans.com/en/news/the-cadillac-v-series-r-under-the-microscope-ready-to-roar-for-america-at-le-mans-59659" target="_blank">Cadillac V-Series.R</a>. 
Thirty-year-old Jack Aitken will join Earl Bamber&nbsp;and S&eacute;bastien Bourdais&nbsp;in the #38 sister car. He will take the seat vacated by Jenson Button, the 2009 Formula One world champion, who is retiring after two seasons with JOTA.

&ldquo;We&rsquo;re delighted to welcome Jack on board,&rdquo;&nbsp;said JOTA Sport director and founder David Clark.&nbsp;&ldquo;We&rsquo;ve been following his progress closely this year and have been really impressed by his raw pace and consistency &mdash; both essential ingredients for success in the Hypercar category. As an existing member of the wider Cadillac Racing driver family, Jack is a natural fit for us. He already understands the culture, the people, and the expectations within the Cadillac ecosystem. Beyond his performance on track, Jack&rsquo;s calm personality and team-first attitude make him an excellent addition to our driver line-up. We never take team chemistry for granted &mdash; six individual stars won&rsquo;t win endurance races, but six drivers who work as one can. Everything we&rsquo;ve seen from Jack so far shows he embodies that spirit, and we can&rsquo;t wait to see what he achieves with the team next season.&rdquo;

Aitken had the chance to try out the Cadillac V-Series.R in its FIA WEC set-up during the Rookie Test held the day after the Bapco Energies 8 Hours of Bahrain. Next season, he will also compete in the IMSA WeatherTech SportsCar Championship with Action Express Racing.&nbsp;&ldquo;I am very appreciative that Cadillac has that trust and are willing to give me the opportunity,&rdquo; said the British racer. &ldquo;It&rsquo;s very exciting for me personally because I&rsquo;ve never raced in the WEC and I&rsquo;ve never raced with JOTA, even though we&rsquo;ve come close a couple of times and have had a relationship that is now coming to fruition. They have fantastic people &ndash; from the drivers to the staff &ndash; and it&rsquo;s a team that has had success in WEC.&nbsp; I&rsquo;m excited to try to take what I&rsquo;ve learned in IMSA at Action Express and bring that across to try to push things forward.&nbsp; I&rsquo;m excited to start the year and to double up on my time in the Cadillac V-Series.R.&rdquo;
