Alex Lynn and Sébastien Bourdais are out. Antonio Felix da Costa and Ricky Taylor are in. Cadillac Racing, riding high off a 2026 IMSA championship, revealed its 2027 driver lineup this week with moves that preserve domestic stability while reshaping its World Endurance Championship assault.

The IMSA side stays largely intact. The No. 31 Cadillac Whelen car keeps Jack Aitken and Frederik Vesti as its full-season pair, with Earl Bamber joining for endurance rounds. The two Wayne Taylor Racing entries, the No. 10 and No. 40, retain their cores too: Ricky Taylor with Filipe Albuquerque, Jordan Taylor with Louis Deletraz.

Will Stevens and Norman Nato fill the endurance slots. A fourth driver for the No. 31 at the Rolex 24 At Daytona remains unannounced.

If it ain’t broke, don’t fix it. Cadillac already owns the IMSA GTP championship. The real story is what happened on the WEC side.

Cadillac Hertz Team JOTA’s two-car Hypercar effort will carry six drivers into 2027: da Costa, Bamber, Aitken, Nato, Taylor, and Stevens. The specific car assignments haven’t been disclosed, but the talent pool got a serious upgrade with da Costa’s return to JOTA and Taylor crossing the Atlantic for dual-program duty.

Da Costa previously raced for JOTA during what the team considers its golden stretch. He holds a WEC title and a class win at Le Mans. Taylor, meanwhile, already got a taste of the JOTA operation earlier this year, subbing in at Circuit of the Americas when Lynn was recovering from surgery.

His 32 IMSA victories and 76 podiums speak for themselves.

The departures of Lynn and Bourdais tell the other half of the story. Bourdais, the four-time Champ Car champion turned endurance ace, has been a fixture of the Cadillac program for years. Lynn, a former Formula E champion, brought global pedigree.

GM’s Eric Warren offered the standard diplomatic farewell, calling their contributions valued and their place in the “Cadillac family” secure.

But warm words don’t change the cold math. Cadillac’s WEC results have not matched its IMSA dominance. Two seasons in the Hypercar class have produced competitive runs but no championship. Swapping out two experienced drivers for a WEC title holder and a battle-tested IMSA champion suggests the patience has limits.

The dual-duty structure is worth watching. Aitken, Bamber, Nato, Stevens, and now Taylor will shuttle between IMSA endurance events and full WEC campaigns. That kind of workload demands precise calendar management and physical endurance, but it also means Cadillac’s best drivers stay sharp across the widest possible range of circuits and conditions.

Warren framed the lineup in terms of chemistry and familiarity. “In a series where teamwork and chemistry are vital, Ricky and Antonio already have a long-standing relationship with everyone at Cadillac,” he said. That phrasing is deliberate.

JOTA’s strength has always been operational cohesion, the ability to extract performance from preparation rather than raw speed alone.

Cadillac enters 2027 heading into its fifth year of GTP competition on American soil and its third in WEC’s Hypercar ranks. The V-Series.R has proven it belongs. The IMSA title confirmed it.

The question now is whether this reshuffled roster can close the gap in a WEC field that includes Toyota, Ferrari, Porsche, and a rapidly improving Peugeot program.

Two WEC rounds remain in 2026. How Cadillac finishes those could shape whether this lineup arrives at Daytona in January with momentum or with something to prove.
