Crash Test Information:
Limited official crash test data available for this era of exotic car. Emphasis on design for occupant safety within a low-volume supercar context.
Braking System:
Four-wheel Disc Brakes, often ABS equipped. Ventilated front and rear discs common.
Seatbelts:
Three-point inertia-reel seatbelts. High-back bucket seats with integrated headrests.
Airbags:
Driver's airbag typically standard from the early 90s, passenger airbag less common in this segment at the time. Check specific model year/trim.
Audio System:
Premium audio systems of the era, often branded (e.g., Alpine, Clarion), with cassette players and radio. CD changers may have been optional.
ABS:
Anti-lock Braking System (ABS) was available/standard on later models, enhancing braking control.
Original Connectivity:
Limited by modern standards; primarily focused on vehicle performance and driver engagement.
Oil Change Interval:
Typically every 6,000-7,500 miles or annually. Refer to manual for exact interval and engine type.
Major Service Interval:
Timing belt replacement is critical; interval varies but often around 30,000-50,000 miles or 5 years. Consult manual for specific engine variant.
Engine Oil Type:
Synthetic 5W-40 or 10W-40 API SL/SJ rated oil is commonly recommended. Consult manual for precise Lotus specification (e.g., API SG or SH, ACEA A2/A3).
Brake Fluid Type:
DOT 4 high-performance brake fluid. Should be flushed and replaced every 2-3 years.
Common Problems:
Electrical gremlins are common in older Lotus models; fibreglass body panel fitment; turbocharger wear; clutch wear; suspension bushing degradation; potential for rust in chassis members if not properly maintained.
Technical Focus Areas:
Proper maintenance of the turbocharged engine's cooling and lubrication systems is vital. Turbocharger performance and reliability are key. Accurate diagnosis of electrical faults is essential.
Manufacturer Philosophy:
Colin Chapman's 'Simplify, then add lightness' philosophy continues to influence Lotus design, even with increased luxury and performance.
Espir Development:
The X180 generation (introduced 1987) evolved through various iterations, with the S4 and S4s models in the 1993-1996 range representing the later, more refined, and powerful versions of the Giugiaro-designed, Peter Stevens-styled car.
Production Period:
Lotus Esprit production ran from 1976 to 2004. The 1993-1996 models represent a significant phase in its development.
