Lotus Éclat: A Comprehensive Guide

The Lotus Éclat, a name derived from the French word for "splendor" or "brilliance," represents Lotus's foray into the world of luxurious, yet sporty, grand tourers. Produced from 1975 to 1982, the Éclat aimed to provide a more refined and practical alternative to the company's existing sports cars, while still maintaining the core Lotus principles of lightweight engineering and exceptional handling. This guide will provide a detailed overview of the Éclat, covering its history, generations, common issues, driving experience, and essential buying advice.

Generations

The Éclat had a relatively short production run, but underwent notable changes during its lifespan. Here's a breakdown of the major iterations:

• Series 1 (1975-1980):
• The original Éclat featured a distinctive fastback coupe design with a large glass rear window.
• Powered by the Lotus 907 2.0-liter DOHC four-cylinder engine.
• Initial models were available with a 4-speed manual or optional automatic transmission.
• Characteristic features include the relatively small rear lights and distinct interior trim.
• Éclat Sprint (1980-1982):
• Introduced in 1980, the Éclat Sprint offered a revised interior and some minor cosmetic updates.
• More significantly, it received an uprated version of the Lotus 907 engine, producing slightly more power and torque.
• Some Sprint models featured a 5-speed gearbox, further enhancing the driving experience.
• Notable changes included larger rear lights, and a redesigned dashboard with improved instrumentation.

Reliability & Common Issues

Owning a classic Lotus requires understanding its quirks and potential maintenance challenges. The Éclat is no exception. Here's a detailed look at some common reliability issues:

Engine (Lotus 907)

The Lotus 907 engine is a complex and sophisticated unit. While capable of delivering strong performance, it's also known for its sensitivity to proper maintenance. Key areas of concern include:

• Timing Belt: Regular timing belt replacement is absolutely crucial. Failure to do so can lead to catastrophic engine damage. Recommended interval is typically every 24,000 miles or 2 years, whichever comes first.
• Oil Leaks: The 907 engine is notorious for oil leaks, particularly from the cam covers, crankshaft seals, and oil pump. Regular checks and proactive resealing are necessary.
• Cooling System: Overheating can be a serious problem. Ensure the cooling system is in good condition, with a properly functioning radiator, thermostat, and water pump. Check for corrosion and leaks frequently.
• Carburetion/Fuel Injection: Early models used carburetors, which can be prone to tuning issues. Later models might have fuel injection. These components require careful adjustment and occasional maintenance to ensure optimal performance.

Chassis & Suspension

The Éclat's chassis provides excellent handling, but requires careful inspection for corrosion:

• Chassis Corrosion: The steel backbone chassis is susceptible to rust, especially in areas exposed to moisture and road salt. Thoroughly inspect the chassis rails, suspension mounting points, and outriggers for signs of corrosion. Repairing rust on the chassis is often an expensive undertaking.
• Suspension Components: The suspension components, including bushings, ball joints, and shock absorbers, can wear out over time, affecting handling and ride quality. Regular inspection and replacement are recommended.
• Brakes: Ensure the brakes are in good working order. Check the brake lines for corrosion and the calipers for leaks. The handbrake mechanism can also be prone to problems.

Body & Interior

The fiberglass body and interior components have their own set of potential issues:

• Fiberglass Cracks: The fiberglass body can develop cracks, especially around stress points and panel joints. Repairing fiberglass can be time-consuming and costly.
• Interior Trim: Interior trim pieces, such as the dashboard, seats, and door panels, can deteriorate over time due to age and exposure to sunlight. Finding replacement parts can be difficult.
• Electrical System: Like many British cars of the era, the Éclat's electrical system can be temperamental. Check for loose connections, corroded wires, and faulty switches.

Driving Experience

The Éclat offers a unique and rewarding driving experience, characterized by its nimble handling and distinctive character.

Pros:

• Excellent Handling: The Éclat's lightweight construction and well-designed suspension provide exceptional handling and cornering capabilities.
• Distinctive Styling: The Éclat's fastback coupe design is both elegant and eye-catching, making it a head-turner on the road.
• Comfortable Ride: Compared to some other Lotus models, the Éclat offers a relatively comfortable ride, making it suitable for longer journeys.
• Unique Engine Sound: The twin-cam engine produces a characteristic roar when revved

Cons:

• Maintenance Intensive: As with any classic car, the Éclat requires regular maintenance and attention to detail.
• Parts Availability: Finding replacement parts can be challenging and expensive, requiring patience and resourcefulness.
• Reliability Issues: The Éclat is known for its potential reliability issues, particularly with the engine and electrical system.
• Limited Practicality: While a GT, the rear seats are small and best suited to children, and the boot area isn't enormous.

Buying Advice

If you're considering purchasing a Lotus Éclat, here's some advice to help you make an informed decision:

Years to Look For:

• Éclat Sprint (1980-1982): The Sprint models offer improved performance and updated interiors compared to the earlier versions. The 5-speed gearbox is a desirable feature.

Years to Avoid (Potentially):

• Early Series 1 (1975-1976): These early models may have more reliability issues and fewer refinements compared to later versions. However, some collectors value these for their originality.

Key Inspection Points:

• Chassis Condition: Thoroughly inspect the chassis for rust, paying particular attention to the areas mentioned above. This is the most critical area to check.
• Engine Condition: Check for signs of oil leaks, overheating, and unusual noises. Compression test is advisable. Review the service history carefully to ensure regular maintenance has been performed.
• Body Condition: Inspect the fiberglass body for cracks, particularly around stress points. Check the paintwork for fading or damage.
• Interior Condition: Examine the interior trim for wear and tear. Check the operation of all electrical components.
• Documentation: Look for a comprehensive service history and any available original documentation. This can provide valuable insights into the car's past.

General Tips:

• Get a Pre-Purchase Inspection: Have the car inspected by a qualified mechanic who is familiar with Lotus vehicles.
• Join a Lotus Club: Connect with other Lotus enthusiasts for advice, support, and access to parts.
• Be Prepared for Maintenance: Budget for regular maintenance and potential repairs. Owning a classic Lotus requires a commitment to ongoing care.
• Factor in Running Costs: Insurance and fuel can be more expensive than with a modern car.

The Lotus Éclat is a rewarding classic car to own, offering a unique blend of performance, style, and character. With careful research, thorough inspection, and a commitment to maintenance, you can enjoy the pleasures of owning this iconic grand tourer.
