HMV Freeway

Also known as Free-Way, Freeway II, H-M-Vehicles Free-way

One seat, one door, one headlamp and one cylinder. If the 12 hp Freeway would not do 100 miles to the US gallon at a steady 40 mph, about 2.35 litres per 100 km at 64 km/h, High Mileage Vehicles of Minnesota would give you your money back. It had no reverse gear.

How big is it?

True proportion

2.92 m

It is 49 mm shorter than a Fiat 500, about 1.7 adults laid end to end.

  • 1.35 m wide
  • 318 kg: about four adults
  • One seat, with a three-point harness
  • An 11-litre (3 US gallon) tank as standard
Drawn at true proportion. The track is 3.6 metres long; the adult stands at the same scale. The Peel P50 is the smallest production car, on every page for comparison.

The story

History

David Edmonson started on a car of his own in 1970, and his rule, as the owners’ club gives it, was to build it small and light.source 1 By the club’s account his prototype won a real-road mileage contest run by the SAE in 1977, at 2.9 litres per 100 km (80.3 US mpg), and again in 1978, at 2.7 litres (88.3 mpg).source 1 In 1978, with backers behind him, he announced two models for early 1979: an open Freeway with a snap-down cover and the smaller engine, and the enclosed Freeway II with a bigger one. The smaller engine came with the 100 mpg guarantee, the larger was expected to do about 2.9 litres per 100 km (80 mpg) at 64 km/h, and an electric model was offered. A factory was set up and orders were taken.source 1

Snowmobile parts

The Freeway was a three-wheeler with two wheels at the front and a lone driven wheel at the back. A Tecumseh air-cooled single, of 340 cc and 12 hp or 450 cc and 16 hp, sat behind the driver and drove through a variable belt of the kind used on snowmobiles to a jackshaft, then by chain to the rear wheel. There was no reverse; one was promised for the Deluxe and never made.source 2source 1 The frame was a welded steel-tube ladder with a second frame round it at bumper height, the suspension was independent all round, and the two-piece body was glass fibre about 3.2 mm thick, coloured in the moulding, red, yellow or orange as standard, with a full undertray beneath. It had one seat with a three-point harness, and a single headlamp.source 2source 1 At 2,921 mm (115 in) long and about 318 kg (700 lb), it could be registered as a motorcycle under federal rules, though some states took it as a car.source 2source 3 MTDM jokes that no helmet was needed, since the car was one.source 3

Thirty hours a car

The backers could not pay the bills, and after a split with one of them, Vexilar, in August 1979 Edmonson cut back, moved production and built only the hard-top, in Standard and Deluxe trim. The prototypes, with wings, a blended bumper and twin headlamps, looked different from the cars that followed. Orders had grown from 200 to over 1,000, on small refundable deposits.source 1 Six pilot cars were built in December 1979 and the first six production cars in March 1980. Money was always short: suppliers wanted cash in advance, and each car took 30 hours to build. One customer, order number 38, received the car in August 1980, 18 months after he ordered it, and about two-thirds of the orders were cancelled before delivery.source 1 By August 1981, 350 petrol cars and 15 electric ones were reported built.source 1

The electric Freeway had a 4 hp motor and four batteries behind the seat, later six, which made it very heavy at the back. The club tells of a Stanford professor, Bob Schneeveis, who tipped one onto two wheels while testing its stability, and of a Department of Transportation report that called the electrics extremely unstable.source 1 A diesel was listed but never ordered.source 2source 1

In 1982 HMV sent cars to dealers as samples, hoping to build a network, but fuel prices fell and sales fell with them.source 1source 3 The company went bankrupt in June 1982, after about 700 Freeways.source 2source 3source 1 By the club’s account the leftover stock paid the bills: one employee was paid in three cars, and a lawyer took one as his final fee. D&A Vehicles of Minnesota bought the rights and in 1984 built 15 Minikins, a two-seat convertible; MTDM says only a handful.source 1source 3 MTDM also points out that the later Elio three-wheeler claimed exactly the 84 mpg it says the Freeway had claimed.source 3

Orders and deliveries

About 700 soldAbout 700 Freeways were sold before High Mileage Vehicles went bankrupt in June 1982, by English Wikipedia, which cites the owners’ club, and by MTDM in its own words. More than 1,000 had been ordered, but about two-thirds of the orders were cancelled.

Famous for

Three points

  1. A guarantee of 100 mpg

    The 12 hp car came with a money-back promise of 2.35 litres per 100 km at a steady 64 km/h.source 2source 1

  2. One of everything

    One seat, one door, one headlamp and one cylinder.source 3

  3. No reverse

    Reverse was promised for the Deluxe and never fitted.source 2source 1

Racing and records

Economy and electric trials

The owners’ club records the Freeway’s wins in economy contests before production began, and an electric event whose date it does not give (more in racing and rallying).source 1

2.9 l/100 km
(80.3 US mpg): the prototype’s winning figure in the SAE real-road mileage contest of 1977.source 1
2.7 l/100 km
(88.3 US mpg): its winning figure in the same contest in 1978.source 1
50 km
endurance test won by an electric Freeway towing a trailer of 13 batteries; a six-battery car did well over 25 km.source 1

Survivors and collecting

Today

How many survive is not known, but the owners’ group, set up online and run by Michael Perry, keeps a database of surviving cars by serial number and date.source 2source 1 Leo’s Garage lists where parts can be found.source 4 Freeways turn up from time to time on eBay and Barn Finds, but none has been traced in a major auction.source 3 The photograph on this page shows a red 1981 Freeway at the Western Antique Aeroplane and Automobile Museum in Hood River, Oregon.
