Lotus ECU (specific model varies, e.g., MBE)
Cdot Impact Resistance:
N/A (Not typically rated by NHTSA/Euro NCAP in the same manner as mainstream vehicles due to low production volume and market segment).
Braking System:
Lotus-tuned ABS, lightweight alloy calipers, ventilated discs.
Traction Control:
Not typically fitted on these early 111S models.
Airbags:
Driver's airbag standard.
Roll Over Protection:
Integrated roll-over hoop structure within the chassis.
Seatbelts:
3-point inertia reel seatbelts, often with harnesses for track use.

Oil Change Interval:
Every 12 months or 9,000 miles (15,000 km), whichever comes first. Check manual for specific conditions.
Major Service:
Detailed inspections recommended at 24,000 miles (40,000 km) or 24 months. Includes cambelt check/replacement (refer to manual for specific K-series VVC requirements).
Engine Oil:
Refer to manual for specific viscosity (e.g., Castrol Edge 10W-40 or 10W-30 for K-Series). Consult manual for precise API/ACEA ratings.
Coolant:
Ethylene Glycol based antifreeze, typically 50/50 mix with distilled water. Refer to manual for specific OAT or HOAT type.
