Depth:
Comprehensive, covering from basic maintenance to detailed component overhauls and repairs, suitable for skilled DIY mechanics and professional technicians.
Engine Type:
Rover K-Series 4-cylinder, DOHC, 16-valve
Displacement:
1.8 Liters (1796 cc)
Horsepower:
Typically 118 hp (1.8i) or 160 hp (1.8 VVC - Variable Valve Control) for naturally aspirated models. Supercharged variants (190 hp) were also available, though often designated by their supercharger name, e.g., 'Exige' variant within Elise lineage.
Torque:
Varies by variant; e.g., ~165 Nm for the 160 hp VVC engine.
Fuel Delivery:
Multi-point fuel injection (MPI)
Fuel Type:
Unleaded gasoline (95-98 RON)
Length:
Approx. 3700 mm (145.7 in)
Width:
Approx. 1700 mm (66.9 in)
Height:
Approx. 1130 mm (44.5 in)
Curb Weight:
As low as approx. 700-750 kg (1543-1653 lbs) depending on specification.
Wheelbase:
Approx. 2300 mm (90.6 in)
Crash Safety:
As a low-volume, specialist sports car, formal crash test ratings like NHTSA or Euro NCAP may not be directly comparable or extensive. Focus is on intrinsic safety through chassis design and driver control.
Braking System:
Typically 4-wheel disc brakes, often with AP Racing or similar performance-oriented components.
ABS:
ABS was often an option or standard on later S1 models, but not universally present on all early examples.
Airbags:
Driver's airbag typically standard; passenger airbag often omitted to save weight.
Roll Over Protection:
Integrated roll bar and reinforced A-pillars within the aluminum chassis structure.
Oil Change:
Typically every 12,000 km (7,500 miles) or 12 months, whichever comes first. Check manual for specific recommendations.
Other Inspections:
Inspection of suspension components, brake system, fluid levels, and drive belts recommended at similar intervals or as per specific mileage milestones.
Engine Oil:
Viscosity: 10W-40 or 5W-40 synthetic. Specification: API SJ or higher. Capacity: Approx. 4.5 liters (with filter).
Coolant:
Ethylene glycol-based antifreeze, mix ratio 50:50 with distilled water. Refer to manual for specific Lotus coolant type.
Brake Fluid:
DOT 4 or DOT 5.1, depending on manufacturer recommendation for ABS systems if fitted. High-temperature performance is critical.
Gearbox Oil:
Likely API GL-4 or GL-5, viscosity 75W-90. Specific Lotus-approved fluid recommended. Capacity: Approx. 2.0 liters.
Head Gasket:
The K-Series engine, particularly in early or hard-driven applications, can be prone to head gasket failure if overheating occurs or if not properly maintained. The manual would detail proper torque sequences and coolant procedures.
Clutch Release Bearing:
Wear and noise from the clutch release bearing is a known concern on some K-series applications.
Composite Body Repair:
Repairing or bonding composite body panels requires specialized adhesives and techniques, which would be covered in detail.
Lotus Philosophy:
Founded by Colin Chapman, Lotus has a long-standing reputation for lightweight construction, aerodynamic efficiency, and superior handling ('Add lightness').
Elise Genesis:
The Elise was conceived as a spiritual successor to the Lotus Elan, emphasizing raw driving pleasure and affordability within the sports car segment.
Series 1 Development:
The Series 1 (S1) Elise, launched in 1996, featured the revolutionary extruded aluminum chassis and composite body panels, setting a new benchmark for lightweight sports car design.
Manufacturing Location:
Hethel, Norfolk, England
Handling Acclaim:
Consistently praised by automotive journalists and enthusiasts for its class-leading handling, steering feel, and chassis feedback. Often cited as a benchmark for pure driving engagement.
Consumer Reviews:
Highly regarded by owners for its driving experience, though sometimes criticized for practicality and interior refinement compared to more mainstream sports cars.
