The 18th edition of the Autosport 3 Hours will be organised by the Historic Sports Car Club on the Snetterton 200 circuit on Sunday 23 April 2023.

The three-hour endurance race for Pre ’66 GT cars will run with the support of Autosport magazine at the unbeatable entry fee of just £1295 per car.

This will be the 18th running of a famous race that began in the late 1950s. In period, Jim Clark (twice) and Jack Sears were winners while in more recent times winners have included Simon Hadfield, Chris Ward and Martin O’Connell. After an eight-year sabbatical, the race is being brought back to the historic racing calendar and will be for GT cars, as it was in the late 1950s and early 1960s.

The race is open to all owners and drivers of Pre ’66 GT cars, regardless of whether or not they normally race with the HSCC. The spirit of the race will be friendly, sporting and inclusive. High standards of on- and off-track behaviour will be expected and enforced.

It will be a non-championship race with a maximum grid of 38 cars plus reserves. There will be 50 minutes of qualifying on Sunday morning and one, two or three drivers per car.

The entry fee is just £1295 per car: that’s £1000 cheaper than some comparable 2022 fees and easily the best value for a historic race of this type and up to half the price of some three-hour races. All entrants will be offered day membership of the HSCC as part of the entry fee, if required.

Refuelling will only permitted in the pit lane outside the allocated pit garage for each entrant. Each car will be required to make a minimum of two five-minute pit stops during the race. At each mandatory pit stop the car must remain stationary for a minimum of five minutes even if the car is not being refuelled. There is no pit stop window for this race.

The overall winners will receive the Autosport 3 Hours Trophy and there will be awards for each class winner. The grid will be divided into classes as follows:

A: Standard, competition GT & GT prototype cars up to 2500cc (excluding metal-bodied cars)

B Metal-bodied standard & competition GT cars up to 2000cc

C All standard competition GT and GT prototype cars 2001 to 4000cc

D All standard competition GT & GT prototype cars over 4000cc

E All standard competition GT & GT prototype cars up to 1300cc
