This must-see family spectacular will bring some of the world's most exclusive and desirable cars to this epic weekend to celebrate all things automotive.

More than 1,000 vehicles will be on display over the weekend, from supercars to classics, Americana to the highly modified and the "interesting".

The event will also host a £50m-plus hypercar enclosure in the shadow of Knebworth House.

Event supporter Zach’s Garage will be hosting hypercars and supercars, as well as extremely valuable vehicles worth in excess of £1million each.

Among the rare motors joining the display will be the 'Hero Car' of the event, the 24ct gold leaf inlayed Koenigsegg Regera.

This was one of the stunning vehicles that drove into Knebworth last Tuesday for an exclusive promo press launch.

Also on show at Knebworth last week was a Bugatti Chiron.

The luxury Koenigsegg Regera is one of the most expensive and fastest cars in the world.

Made in Sweden, the Koenigsegg set a new 0-400-0 km/h world record in 2019 when a Regera completed the run in 31.49 seconds – with just one gear!

Its limited production, combined with its cutting-edge revolutionary technology, make it one of the most exclusive cars on the road in the world today.

In addition, over 50 car clubs are set to attend the Knebworth event, so enthusiasts will see an incredible array of classics, highly modified, American and supercars.

There will be a programme of events within the main arena. The highlight will be the ‘Petrolheadonism Elite 2021’ competitors, displaying the most astounding vehicles from seven varied classes, presented by seven different experts in their field.

These cars will parade around a ‘catwalk’ each day creating a moving masterpiece of horsepower.

Visitors are welcome to bring a picnic and explore some of Knebworth Park’s other attractions.

Perfect for a family day out, your ticket to the event includes free on-site parking and free entrance to the adventure playground, the dinosaur trail and 28-acre formal gardens.
