The Lotus Elan Series 1 was the original Lotus Elan. Introduced in 1962 as the Type 26, it established the basic formula that would define the Elan family: a compact two-seat drop head coupé, a fibreglass body, a steel backbone chassis, independent suspension, and a Lotus twin-cam engine. During production it was known as the Elan 1500 and later the Elan 1600. The “Series 1” name came later, after the Series 2 had been introduced.
The Series 1 was a very small and light sports car, but it was not a primitive one. Contemporary descriptions emphasized its twin-overhead-cam engine, all-independent suspension, rubber-cushioned drive, careful interior packaging, and unusually refined road manners for a lightweight sports car. It also introduced many of the visual cues now associated with the Elan, including its low fibreglass body, pop-up headlamps, compact proportions, and simple roadster profile.
Approximately 900 Series 1 cars were produced, including the early Elan 1500 cars and the Type 26R racing variants. The chassis sequence began at 26/0001 and the final Series 1 chassis is listed as 26/3900. Production ran from 1962 to 1964, with the Elan 1600 replacing the Elan 1500 during 1963 and the Series 2 succeeding the Series 1 in 1964.

History
The Elan began as Lotus’s new small sports car project, known internally as M2. It followed the Elite but was conceived around a different construction method: a separate steel backbone chassis carrying a fibreglass body. That approach allowed Lotus to keep the car very light while avoiding some of the complexity of the Elite’s fibreglass monocoque construction.
The Elan was announced in 1962 and appeared at the October 1962 London Motor Show. The display car’s headlamps were propped open mechanically because the car was not electrically connected or running at the show. The early car was introduced as the Elan 1500, using a 1,498 cc version of the Lotus Twin Cam engine. This first version had only a short production run before the enlarged 1,558 cc Elan 1600 replaced it.
The change from Elan 1500 to Elan 1600 took place in 1963. One source gives May 1963 and chassis 26/0023 as the introduction of the 1600, while another gives chassis 26/0026. The difference is small but unresolved in the supplied material. The same period also brought the optional hardtop. From that point forward, the Elan 1600 became the main Series 1 production model.
Although enthusiasts now call these cars “Series 1,” that name was not used as the original marketing identity. The retrospective Series 1 label became useful after the Elan S2 arrived in 1964. In period, the car was identified more naturally as the Elan 1500 or Elan 1600.
The Series 1 also reached the United States early in its life. A December 1963 test car was described as the first Elan brought in by a United States dealer, with West Coast importing associated with Bob Challman of Manhattan Beach, California. Fewer than 300 cars were planned for United States import during 1964. East Coast importing was associated with Cox & Pulver, Inc. in New York.
By November 1964, the Series 1 chassis sequence had reached its final listed number, 26/3900. It was then replaced by the Series 2, but the basic Elan concept had already been established: a very light car with quick steering, strong performance for its capacity, and a reputation for exceptional handling.
Production Notes
The supplied sources agree on the broad Series 1 production story but preserve several useful details and conflicts. The first production chassis is identified as 26/0001. The change to the Elan 1600 occurred in May 1963, although the exact first 1600 chassis is listed differently by different sources. The final Series 1 chassis is listed as 26/3900.
| Date | Type 26 chassis | Notes |
|---|---|---|
| January 1963 | 26/0001 | Elan 1500 introduced; first production chassis |
| May 1963 | 26/0023 | Elan 1600 introduced, according to Robinshaw & Ross |
| May 1963 | 26/0026 | Hardtop available as an option; Taylor gives this as the 1600 change point |
| January 1964 | 26/0330 | Series 1 production continued; no specification change noted |
| November 1964 | 26/3900 | Final listed Series 1 chassis number |
Kit-car sales complicate production dating. A car’s first registration date should not be assumed to be the same as its build date because some kits remained in component form at dealers before being purchased and assembled.
Unit Numbers
The supplied production estimate is approximately 900 Series 1 cars. That figure includes the early Elan 1500 cars and approximately 52 Type 26R racing variants. One cited 1966 report stated that about 900 S1s were made before the upgrade to S2. Another later figure gives about 850 Series 1s, but the difference narrows if roughly 50 26R variants are treated separately.
The early Elan 1500 count is also not perfectly settled. The supplied facts state that approximately 22 to 25 Elan 1500s were built, while one source cited within the facts page gives only eleven smaller-engined cars and another passage in the same source says no Elans were sold with the smaller 1,500 cc engine. Because the supplied page flags this as a conflict, the safest wording is that the Elan 1500 had a very short production run, most likely in the low twenties, pending stronger confirmation.
Known individual cars in the supplied material include chassis 26/0064, a 1963 S1 registered 373 GNX, and chassis 26/0159, first registered 15 July 1963. These examples support the early Type 26 numbering sequence beginning at 26/0001.
Engines
The Series 1 used two versions of the Lotus Twin Cam engine. The first cars were Elan 1500s with a 1,498 cc engine. The later Elan 1600 used the enlarged 1,558 cc Lotus Twin Cam, based on the Ford Kent Pre-Crossflow engine.
The early 1,498 cc cars were short-lived. Contemporary and later sources in the supplied facts describe approximately 22 cars, or a range of 22 to 25 cars, before the larger 1,558 cc unit replaced the original engine. By September 1963, early cars were described as having the smaller engine, while later models were being produced with the 1,558 cc unit.
Period road tests praised the engine’s flexibility and character. One contemporary description emphasized flexibility, a flat torque curve, docility, and quietness. Another described the 1600 engine as tractable, quiet, and strong from 2,000 to 6,500 rpm in top gear. A governor rotor arm was factory-fitted in the distributor and set to cut out at 6,600 rpm. The practical recommended limit was around 6,500 rpm, although one test noted 7,000 rpm being used without apparent stress.
Chassis, Body, and Design
The Series 1 used a fibreglass body mounted on a steel backbone chassis. This became one of the defining Elan features. The body was made from five main mouldings: the body shell, bonnet, boot lid, and two wide-opening doors. The body shell itself was formed from inner and outer GRP halves bonded together, with metal framework incorporated around the door apertures.
The body design was compact and low, with pop-up headlamps recessed under swivelling covers when not in use. The headlamp concept is credited in the supplied material to Ron Hickman, with vacuum taken from the inlet manifold. The lamps were raised and lowered using vacuum cylinders and a vacuum reservoir, with dashboard switching and a flashing control.
The bumpers were also distinctive. They were foam-filled fibreglass pieces that continued the body lines rather than looking like separate add-on bars. Their design is also associated with Ron Hickman and was described as resistant to minor cracking, denting, and bending.
The engine hood was front-hinged and ran in nylon runners. It could be removed completely in about ten seconds. At the rear, the luggage compartment was carpeted and supplemented by additional space behind the seats. Supplied sources disagree on exact luggage volume, giving both 8 cu ft and 5.9 cu ft, so both values should be treated as source-specific rather than definitive.
Interior and Driving Environment
The Series 1 cockpit was simple, compact, and purposeful. The dashboard was an oiled teak panel and also served as a structural member of the body. It carried matching speedometer and rev counter instruments in front of the driver, with oil pressure and water temperature, fuel gauge, switches, and an open glove compartment arranged across the panel.
The interior was trimmed in Vynide and fully carpeted. A three-spoke wood-rimmed steering wheel and wooden gear lever knob were standard features. Seats were fixed-back bucket seats mounted on angled runners; as the seat moved forward it also rose and tipped slightly forward, helping shorter drivers see out while still allowing sufficient adjustment for six-foot occupants. The seat backs were not adjustable.
The cockpit had some ergonomic compromises. Several period comments noted narrow pedal spacing, limited foot room caused by the tunnel, and a handbrake placed under the dashboard. The handbrake was described as an umbrella-handle type. Heel-and-toe operation was possible, but tight footwear helped. Some testers also noted that the brake foot could catch the accelerator unintentionally.
Weather protection was better than might be expected for such a light open car but not perfect. The soft top used PVC fabric with separate clip-on fibreglass cant rails around the side window apertures. It could be erected in less than five minutes when unhurried, but the process was more mechanical than modern convertible tops and could require fitting pegs, joining sections, tucking ends, and using a small wrench. One test found it snug and rainproof, while another noted water leaks by the door posts and side windows that could drop from the closed position while driving.
Options
The Series 1 was available with several options and extras. The hardtop and tonneau cover were among the important Series 1 options. The hardtop appears in the supplied sources in two forms: a factory hardtop listed in the Autocar pricing and a Surbiton Motors fastback hardtop shown at the 1964 London Racing Car Show.

Performance Data
The Series 1’s performance varied by test car, test conditions, gearbox, tyres, and measurement method. Period figures generally place the Elan 1600 at about 7.2 to 9.0 seconds from 0 to 60 mph, with top speeds from about 107 to 115 mph in measured tests.
| Source | Date | Differential ratio | 0–60 mph | 0–100 mph | Top speed |
|---|---|---|---|---|---|
| Road & Track | December 1963 | 3.90 | 9.0 sec, two-up | 22.0 sec, two-up | 107 mph |
| Car and Driver | February 1964 | 3.90 | 7.2 sec | 22.1 sec | 112 mph |
| Autocar | 21 August 1964 | 3.90 | 8.7 sec | 26.8 sec | 114.2 mph mean / 115.0 mph best |
| Motor | 26 September 1964 | 3.9 | 9.0 sec | 24.1 sec | 112.5 mph |
| Zero to 60 Times / Car Folio | 1964 | — | 8.6 sec | — | — |
Road & Track’s December 1963 test used two occupants with a combined weight of approximately 400 lb. It recorded 0–60 mph in 9.0 seconds, 0–100 mph in 22.0 seconds, and the standing quarter mile in 16.9 seconds at 86.6 mph. The text estimated that a single-occupant run would produce about 8.5 seconds to 60 mph.
Car and Driver’s February 1964 test was quicker to 60 mph, recording 7.2 seconds and a standing quarter mile of 15.6 seconds at 87 mph. Autocar’s August 1964 test recorded 8.7 seconds to 60 mph, 16.4 seconds for the standing quarter mile, and a best top speed of 115.0 mph.
Autocar also recorded maximum speeds by gear:
| Gear | Maximum speed |
|---|---|
| 1st | 46 mph |
| 2nd | 70 mph |
| 3rd | 92 mph |
| Top | 114.2 mph mean / 115.0 mph best |
Fuel economy also varied by test and by gallon type. Road & Track reported 22–26 mpg using US gallons. Autocar reported 27.9 mpg overall over 1,333 miles, with a normal range of 26–35 mpg using Imperial gallons. These figures should not be directly compared without accounting for the different gallon sizes and test conditions.

Pricing
At announcement, the Elan was listed at £1,499 fully built and £1,095 as a kit. One January 1963 source gives the kit price as £1,090, a small £5 discrepancy that may reflect rounding or a minor price change. The kit format was important to the Elan’s early market position and also explains why registration dates can be misleading.
Sports Car Graphic’s January 1963 comparative pricing placed the assembled Elan 1500 below the Lotus Elite, E-type Jaguar, Alfa Romeo Giulietta Spyder, and Porsche 1600, while the kit price was much lower.
| Make / model | UK price | US equivalent |
|---|---|---|
| Lotus Elan 1500, assembled | £1,499 | $4,200 |
| Lotus Elan 1500, kit | £1,095 | $3,050 |
| Lotus Elite | £1,948 | $5,450 |
| E-type Jaguar | £2,036 | $5,700 |
| Daimler SP 2.0 | £1,451 | $4,000 |
| Alfa Romeo Giulietta Spyder | £1,690 | $4,750 |
| Porsche 1600 | £2,163 | $6,100 |
United States pricing later in 1963 and 1964 varied by coast and preparation. Road & Track listed a December 1963 US list price of $3,822 and a West Coast port-of-entry price of approximately $4,000 including built-in heater, de-crating, and preparation. Car and Driver listed an East Coast port-of-entry price of $4,295 in February 1964.
Road Test Impressions
The strongest theme running through the period test material is that the Elan drove like a serious sports car while offering a level of refinement that surprised testers familiar with earlier lightweight Lotus cars. Jim Clark was quoted as saying that the ride was superb and that the handling was even better than the Elite’s.
Several testers highlighted the steering and handling. Early commentary described the road manners as immaculate, with little lean or tyre squeal, and steering that felt taut and well bred. Another test found mild understeer when pressed hard, easily corrected on wet roads with a little more steering lock. Autocar’s later assessment called the Elan a thoroughbred sports car because its character came so directly from Lotus racing experience.
The engine received similar praise. Period comments emphasized tractability, flexibility, quietness, and useful torque rather than only peak speed. The car’s light weight meant the engine did not need large displacement to feel quick.
The car was not without faults. The soft top was more complicated than many modern drivers would expect. The cockpit could feel hemmed in among larger vehicles. Pedal spacing was tight. The handbrake position drew criticism. Some cars showed water leaks, window movement, or uneven carburetion. But the overall impression was that the Elan’s handling, ride, steering, and performance made those flaws acceptable in a focused sports car.
