Lotus Elan Sprint

Lotus Elan Sprint

The 1971 Lotus Elan Sprint represents the final, finest evolution of what many consider the most important sports car Lotus ever built. Introduced in February 1971, the Sprint was the last Elan variant produced before the model was replaced by the Elan Plus 2S 130, and it concentrated everything Lotus had learned about the platform into one definitive specification.

The 'Big Valve' twin-cam engine, displacing 1,558cc, produced 126 horsepower in its highest state of tune -- an extraordinary figure that equated to over 80 horsepower per liter from a naturally aspirated engine using early 1970s technology. The Big Valve designation referred to the larger intake and exhaust valves that improved gas flow at high rpm, while revised camshaft profiles and polished ports contributed to the engine's exceptional specific output.

The twin-cam's character was pure Lotus. Below 3,000 rpm, it was docile enough for traffic. Above 4,000 rpm, it came alive with an urgency and willingness to rev that was intoxicating. The peak power arrived at 6,500 rpm, and the engine remained on song to beyond 7,000 rpm. Twin Dell'Orto or Weber carburetors provided the fuel delivery, and their response to throttle inputs was immediate and precise.

At approximately 686 kg (1,512 lbs), the Sprint achieved a power-to-weight ratio that many modern sports cars struggle to match. This extreme lightness, combined with the twin-cam's punch, created acceleration that felt explosive relative to the modest displacement. The Sprint could reach 60 mph in approximately 6.7 seconds and achieve a top speed of 122 mph.

The Sprint's handling was the stuff of legend. The backbone chassis provided a rigid platform for the four-wheel independent suspension to work against, and the result was a level of precision, feedback, and adjustability that made the Elan a driving instructor's reference point. The car responded to weight transfer, throttle position, and steering input with uncanny accuracy, rewarding skilled drivers with an experience that bordered on telepathic.

Disc brakes at all four corners provided stopping power that was more than adequate for the Sprint's light weight, and the unassisted rack-and-pinion steering was perfectly weighted with exceptional feel.

The Sprint was visually distinguished by its two-tone paint scheme, with contrasting colors divided at the body's shoulder line. This distinctive treatment, combined with the gold 'Sprint' badges, made the car immediately identifiable as the top-specification Elan.

The 1971 Sprint represented the culmination of nearly a decade of Elan development. Every weakness had been addressed, every system refined, and every component optimized. The result was a sports car that, despite its age, remained competitive with far newer designs -- a testament to the fundamental rightness of Chapman's original concept.

Today, the Sprint is the most sought-after Elan variant, commanding the highest prices in the collector market. Its combination of the most powerful engine, the most refined chassis, and the iconic Sprint livery makes it the definitive expression of one of the most influential sports cars ever built.
