Petrolheadonism Underground is set to return to Wembley on 29 and 30 March 2025, bringing thousands of car enthusiasts together for a weekend dedicated to automotive culture.
The event will showcase hundreds of supercars, alongside a lineup that includes retro, classic, modified, hypercars, and Americana vehicles. Visitors will also have the chance to explore trade stands and suppliers, featuring the latest in automotive technology and design.
Some of the biggest names in the automotive world will be taking part in live interviews on the Carvertical Main Stage in the Green Parking display. Among them are Wheeler Dealer Mike Brewer, Smallest Cog’s Izzy Hammond, Auto Alex, Shmee150, Ratarossa, and many more.
Petrolheadonism Underground will take place in two huge car parks just outside Wembley Stadium, in Wembley Park, providing the perfect setting for a massive display for anyone in attendance.
The EBC Brakes performance and motorsport stage will be another highlight, giving fans an insight into high-performance engineering and motorsport culture.

For 2025, the event is introducing the Dadcars Family Zone, where visitors can ride Razr Karts, take part in car-themed art activities, and check out practical but stylish family cars. One of the big reveals will be the world’s first six-seater Maserati Granturismo, known as the “Daderati.”
In the Pink Lower Zone, DJ Mistacutup will be hosting an underground car show, complete with a laser light display and scratch DJs.
