Scalextric is a toy brand for a range of slot car racing sets which first appeared in the late 1950s, as a creation of British firm Minimodels. The brand is currently owned and distributed by Hornby.


Scalextric came from the Scalex brand of Minimodels Ltd, which was a clockwork powered race car system that first appeared in 1952. Their inventor, B. "Freddie" Francis, showed Scalextric ("Scalex" plus "electric") cars at the annual Harrogate Toy Fair in 1957 in the UK. In 1958, unable to meet demand for the popular range, the parent company was sold to Lines Bros Ltd, which operated as Tri-ang. Its subsidiary Rovex, which specialised in plastic, then developed Scalextric, converting the metal cars to the easier and cheaper to mould plastic. The track, which was originally a rubber compound, later became moulded plastic. Production continued at Minimodels in Havant until 1967, when it moved to Rovex's own site.[1]

When Lines Bros collapsed, its subsidiary Rovex-Triang, which handled Scalextric and the Triang railway brand, was sold off, eventually becoming Hornby Railways. Although Scalextric remained based in the UK, most of the products are now made in China.[1]

Results were hit in 2007 by the closure of the Scalextric Race World retail store in Tacoma; Scalextric-USA created a store front in Auburn, Washington showcasing Scalextric slot cars, tracks and accessories.[2]

Most Scalextric models are 1:32 scale, though between 1968 and 1970 Super124 cars and track were manufactured at 1:24 scale. In the late 1990s, Micro Scalextric at 1:64 scale was introduced. Cars and track are not compatible between scales.

At the beginning of the 21st century, Scalextric track underwent a major redesign to make it easier to assemble. The new design is known as Scalextric Sport and can be connected to the original track using special adaptor pieces. The new track was designed to be compatible with all earlier 1:32 cars.

Other manufacturers, such as Fly,, SCX, MRRC and Ninco, produce cars that can run on Scalextric track without modification.

In 2004 Scalextric Sport Digital (SSD) was introduced, with which up to four digital cars can be raced in a single slot. The cars can change from one slot to another using special slot-lane change tracks, the lane change or otherwise being controlled by a button on the throttle. Sport Digital cars will run on analogue layouts without modification, but analogue cars require a digital decoder to be installed before they can run on a digital layout.[3]

Many of the original Scalextric cars can be fitted with a digital decoder depending on available space within the body shell. Performance of converted cars on a digital system can vary, but enthusiasts have been able to successfully convert a wide range of cars, both from Scalextric and other brands.

As use of Scalextric Digital has increased, a community has established itself where users have developed enhanced powerbase functionality, fuel management and timing systems for increased realism.

To convert Scalextric Sport into Scalextric Digital requires a digital power base, power supply (transformer), lane changing track (to utilise the full benefits), and digital controllers.

In late 2010 Scalextric released a revised six-car digital powerbase, C7042. This powerbase includes a separate screen which aids set up and also displays race information such as lap times. The company worked closely with customers when developing the new system. The result includes features such as yellow flag options for dealing with crashed cars, ghost cars to race against which can run and change lanes automatically, and the ability to race in analogue mode for older models that have not been converted to digital.

In Spain, Hornby Scalextric is marketed under the brand Superslot, as the Scalextric brand is owned there by Tecnitoys, whose products are sold internationally under the SCX brand. Whilst there are some common standards, parts of the two ranges, particularly in their digital offerings, are not compatible.


Scalextric is typically sold as a set containing enough track to make a circuit, the necessary power supply and throttles and two cars. The cars are usually based on real vehicles from Formula 1, A1 Grand Prix, NASCAR, rallying, touring, or Le Mans, or based on ordinary road going cars. A number of novelty sets have been produced; for example, horse racing sets and 360 degree sets. The latter, produced sporadically since the 1960s, have a specially-made guide that enables the car to run back the way it has come by spinning through 180 degrees.


Scalextric have offered a number of TV and film tie-ins, including Batman Begins, Teenage Mutant Ninja Turtles, The Simpsons and the 2007 Live-action Transformers movie. They also produced sets for The Amazing Spider-Man (the 1970s series), Tim Burton's Batman, James Bond 007 1960's, 2012's Skyfall movie in 1:32 and 1:64 scale Knight Rider, Starsky and Hutch, The Italian Job (2003), Top Gear, The Sweeney', The Dukes of Hazzard as well as 1:32 and 1:64 scalex Star Wars sets.

Scalextric has also recently licensed the Need for Speed brand from Electronic Arts and has produced a set based on the popular video game series.

On 22 November 2004, thieves stole 2,500 Simpsons Scalextric sets from the back of a lorry which was parked near services on the M2 motorway in England.[4]


In addition to all types of cars, Scalextric vehicles have included motorbikes, sidecars, go-karts, pickup trucks, SUVs, racing trucks, articulated trucks, horses, skateboards and bicycles.


Standard track consists of straights of various lengths and corners of different radii and degree of turn. Special track includes several different styles of chicane, cross-over tracks, crossroad track and humpback bridge. Novelty pieces of track have included pit lane tracks, Le Mans start, blow-out track and loop-the-loop tracks.[1]

There are five generations of 1/32 scale Scalextric track:

  1. Original Scalextric Track (Mk. 1): This was made from rubber with thin, vertical electrical connectors, and held together with separate metal clips. This track had white lines between the lanes.
  2. Original Scalextric Track (Mk. 2): Released in 1962, the material became plastic, electrical connections were through wider, horizontal pins, and the track was held together by two integrated circular, spoon-shaped pins and sockets moulded into each end. Converter pieces were available to link the two types. It is now known as Classic track. Classic track is compatible with another leading brand, SCX's classic track.
  3. Scalextric Sport: Released in 2001, another plastic track, but with a smoother surface. The track connectors are square and slot into place unlike the ring shaped Classic track ones. Converter pieces are available to link to Classic track.
  4. Scalextric Digital: Released in 2004, Scalextric Digital is compatible with Sport. It allows up to 6 cars on a 2 lane track at one time, with each car fully controllable. This was a feature previously unavailable from Scalextric.
  5. Scalextric Start: Released in 2010, Scalextric Start aims to be a basic track for children. It has only one type of straight and corner, and each set can be made up into various layouts; the cars included in the sets are fantasy models, which reduce manufacturers' licensing costs, and a converter track piece is available to allow cars to cross from Start track to Sport and back again.

Scalextric racing in popular culture[edit]

In 2009, BBC Top Gear presenter James May announced plans to recreate the full length Brooklands racing track using Scalextric track and cars.[5] This was undertaken with a team of 350 volunteers building the track from an uncounted number of pieces of Scalextric track, navigating ponds and roads, closely following the route of the old Brooklands track. This event broke the Guinness World Record for the longest ever Scalextric track in the world, intended to measure the original 2.75 miles (4.43 km) of the original Brooklands circuit but in reality recording 2.95 miles (4.75 km) in length, because of the need to navigate modern features that block the original course. The episode was first shown on BBC2 on 17 November 2009 as part of James May's Toy Stories.

Early Scalextric cars as they appeared[edit]

  • C190 - Le Mans 24Hr Pit Stop - Made up of 4 special pieces of track. (Innovative uses of this include using a multiple number to achieve non-digital lane switching).
  • C209 - Lighting Gantry - Pressing the top button starts the count down. Features traffic lights, and was powered by wires connected to the transformer/PSU.
