Broadspeed GTS classic cars for sale

History of the Broadspeed GTS

Broadspeed Engineering, based in Birmingham, made its mark during the 1960s and 1970s as a respected name in British tuning and motorsport. Founded by Ralph Broad, the company initially carved its reputation preparing and racing Ford Anglias and Escorts, but soon shifted focus to creating high-performance versions of small British cars. The GTS series, developed from the Mini, was Broadspeed’s ambitious answer to the burgeoning demand for compact cars with racing pedigree. Marked by improved aerodynamics and engine enhancements, these models found favour on both the road and historic racing circuits. The GTS was never mass-produced; instead, each car was tailored to customer requirements, making every example notable for its individuality and period upgrades.

Model History

The Broadspeed GTS was derived from the popular Mini, taking the humble city car and transforming it into a bespoke, race-bred special. Unlike mainstream Mini derivatives, the GTS boasted Broadspeed’s own bodywork modifications and powertrain improvements. No direct predecessor existed; rather, it emerged as a natural progression from Broadspeed’s success with Mini racers in UK touring car events. While production numbers were limited, each GTS showcased incremental innovations in tuning and lightweight construction. There was no official successor, as Broadspeed eventually shifted focus towards Ford models in later years, making surviving GTSs even more notable.

Highlights of the Broadspeed GTS

A hallmark of the GTS is Broadspeed’s reimagined fastback profile, achieved by grafting a sloped rear hatch to the Mini bodyshell. This not only improved aerodynamics but gave the GTS instantly recognisable lines. Engine work ranged from mild tune-ups to full race specifications, with enhanced carburettors, free-flow exhausts, and tweaked suspension geometry for spirited handling. The interior could be ordered to individual specification, often featuring Smiths gauges, bucket seats, and custom switchgear—underscoring the bespoke nature of each build.

Technical Data

Special Editions and Collectible Models

Given that all Broadspeed GTS models were built to order, each one can be considered unique, with some cars benefiting from extra competition upgrades such as limited-slip differentials, roll cages, or Webasto sunroofs. Certain vehicles have histories tied to period motorsport, which can further increase their historical significance.

Weak Spots and Common Issues

Originality and provenance are key issues when considering a Broadspeed GTS, as many replicas or partially converted cars circulate in the market. Bodywork—especially the unique fastback conversion—can be prone to corrosion at the joins and sills if not properly maintained. Mechanical wear in tuned A-series engines and modified suspension components is common, and original Broadspeed parts may be difficult to source.

Engine and Performance, Transmission and Handling

With performance depending heavily on individual specification, GTS models generally offer significantly enhanced acceleration and cornering prowess over standard Minis. Power delivery is lively, especially in 1275cc configurations, and the modified suspension geometry allows for agile responses on tight roads or circuits. Most retain the original Mini’s front-wheel-drive layout and four-speed manual gearbox, often with shortened gear ratios for sporting use. Popular configurations include the 1275cc version with Weber carburettor and close-ratio gearbox, as well as cars ordered with full touring car competition upgrades—both highly sought after for historic track events.

Interior, Comfort, Exterior and Design

The most striking design element is the visually distinctive fastback conversion, which gives the GTS a sleeker silhouette than any standard Mini variation. Interior treatments range from minimalistic, race-focused environments to surprisingly luxurious trims, depending on client specification. Accessories such as auxiliary spot lamps, special paint schemes, and period-correct Minilite wheels are frequently found. Materials reflect 1960s-1970s British automotive construction, with a mix of vinyl, fabric, and bespoke dashboard layouts. Certain examples feature rare additions including roll bars, rally trip meters, or tuned exhausts as dealer- or factory-fitted equipment.

Other Relevant Features

Due to the model’s rarity and custom-built nature, verifying the authentic provenance and original specification is crucial when buying or restoring a Broadspeed GTS. Specialist clubs and historic racing organisations often maintain registries to trace car histories.

Summary

The Broadspeed GTS offers a compelling fusion of British engineering ingenuity and motorsport heritage, born from a time when individuality trumped mass production. For connoisseurs seeking something beyond the usual Mini derivative, the GTS delivers mechanical interest, rarity, and unmistakable 1960s character—all with the potential for exhilarating performance in the right hands.
