Bottom Line Up Front
The British government once gave returning disabled veterans a free three‑wheel “Invacar” – a vehicle that soon earned a reputation for flipping over and even catching fire.

Design & Looks
Invacars looked like a cross between a small truck and a wheelchair. The body was a lightweight steel tub with a single front wheel and two rear wheels for stability. Inside, the driver sat in a reclining seat with hand‑controlled steering and brakes. The design was practical for people who could not use foot pedals, but the narrow front track made the car prone to tipping when cornering too fast.

Performance & Mileage
Most Invacars were powered by a tiny 500 cc or 600 cc two‑stroke engine that produced around 8 hp. That was enough for a top speed of 30‑35 mph and a fuel economy of roughly 45‑55 mpg (US). The low power meant the car struggled on hills, and the engine’s heat‑rich exhaust was a known fire hazard, especially when the cooling system failed.

Price & Rivals
Because the cars were given away, veterans paid nothing for the vehicle itself. However, maintenance quickly became a hidden cost. Spare parts were scarce, and the bespoke hand‑controls required specialist mechanics. At the time, the only real rival was the French Microcar, which used a similar three‑wheel layout but had a more stable wheelbase.
By the late 1960s the safety concerns – frequent roll‑overs and occasional engine‑fire incidents – led the government to discontinue the program. The remaining fleet was gradually withdrawn from the roads, leaving a handful of collectors today.

FAQ
What was the typical fuel consumption of an Invacar?
About 45‑55 miles per gallon, depending on engine size and driving conditions.
Did Invacars have any safety features to prevent flipping?
No. The design relied on low speed and careful steering. There were no anti‑roll bars or electronic stability controls.
Are any Invacars still road‑legal today?
Only a few are kept as museum pieces or private collectibles. Modern regulations generally prevent them from being used on public highways.
