The original Esprit, introduced in 1976, was designed by Giugiaro under the code name “Silver Car.” It featured a fiberglass body over a steel backbone chassis, a design philosophy that emphasized lightweight construction. The car was powered by a 2.0-liter inline-four engine, which provided adequate performance but left room for improvement, particularly in the face of increasing competition from other sports car manufacturers.
The decision to introduce a turbocharged version of the Esprit was part of a broader strategy by Lotus to expand its market appeal and compete with more powerful rivals. The Esprit Turbo retained the core characteristics of the original car, including its mid-engine layout and sharp, angular design, while adding significant performance enhancements. This approach was in line with Lotus’s ethos of “adding lightness,” a principle famously championed by the company’s founder, Colin Chapman.
The Turbo variant was developed using a modified version of the 2.2-liter Lotus 912 engine, which was fitted with a Garrett T3 turbocharger. This setup allowed the car to produce significantly more power than the naturally aspirated version, transforming the Esprit into a true high-performance machine. The addition of the turbocharger also necessitated changes to the car’s cooling and fuel systems, as well as the introduction of new components to handle the increased power output.
The Lotus Esprit Turbo was a significant technological achievement, combining advanced engineering with Lotus’s trademark focus on lightweight construction. The car’s heart was its 2.2-liter inline-four engine, known as the 912. This engine, developed by Lotus, featured a double overhead camshaft (DOHC) configuration and was equipped with a Garrett T3 turbocharger, which provided forced induction to boost power output.
In its original form, the Esprit Turbo’s engine produced around 210 horsepower and 200 lb-ft of torque. This represented a substantial increase over the naturally aspirated version of the Esprit, which had previously been criticized for lacking sufficient power. The turbocharged engine allowed the Esprit Turbo to achieve a top speed of approximately 150 mph and accelerate from 0 to 60 mph in under six seconds, making it one of the fastest cars of its era.
The Esprit Turbo’s performance was further enhanced by its lightweight construction. The car featured a fiberglass body mounted on a steel backbone chassis, a design that provided excellent rigidity while keeping weight to a minimum. This construction method, combined with the car’s mid-engine layout, resulted in exceptional handling characteristics, with a near-perfect weight distribution that contributed to its agility and responsiveness.
The suspension system of the Esprit Turbo was designed to provide a balance between comfort and performance. It featured independent suspension with coil springs and telescopic dampers at all four corners, along with anti-roll bars to reduce body roll during cornering. The car was equipped with ventilated disc brakes at the front and solid discs at the rear, providing ample stopping power to match its performance capabilities.
Aerodynamically, the Esprit Turbo benefited from several design features that reduced drag and increased downforce. The car’s low, wedge-shaped profile minimized air resistance, while a front spoiler and rear wing helped to stabilize the car at high speeds.
