Engine Bore Stroke: 1.8L: 80.0 mm x 88.5 mm; 2.0L: 84.5 mm x 88.5 mm Engine Horsepower Ps: 1.8L: Approx. 122 PS (120 hp); 2.0L: Approx. 130 PS (128 hp) Engine Torque Nm: 1.8L: Approx. 160 Nm (118 lb-ft); 2.0L: Approx. 170 Nm (125 lb-ft) Fuel System Fuel Delivery: Typically equipped with twin downdraft Weber or Dell'Orto carburetors (e.g., 40 DCNF or 40 DHLA). Fuel Type: Unleaded Gasoline (premium recommended) Ignition System Ignition Type: Distributor-based ignition system, typically with breaker points and condenser or early electronic ignition. 🔧 Transmission Standard Transmission Type Standard: 5-speed manual transaxle Optional Transmission Type Optional: Some early models may have been available with an automatic transmission, though manual was standard and preferred. Features Transaxle Layout: Rear-mounted transaxle, combining gearbox and differential for near-perfect weight distribution. 📐 Dimensions Exterior Wheelbase Mm: Approx. 2510 mm (98.8 in) Length Mm: Approx. 4240 mm (167 in) Width Mm: Approx. 1670 mm (65.7 in) Height Mm: Approx. 1360 mm (53.5 in) Weights Curb Weight Kg: Approx. 1150-1250 kg (2535-2755 lbs) depending on engine and equipment. Front Rear Weight Distribution: Near 50/50 due to rear transaxle design, contributing to exceptional handling. 🛡️ Safety Features Active Features Braking System Design: Four-wheel Dunlop disc brakes, often with a dual-circuit hydraulic system for safety. Suspension Design: Independent front suspension (often trailing arms or MacPherson struts), De Dion rear axle with Watts linkage, providing excellent roadholding and stability. Passive Features Body Construction: Unitary body construction with integrated crumple zones, though passive safety standards of the era were less stringent than modern vehicles. 💡 Technology Features Infotainment Infotainment System: Basic analog instrumentation: speedometer, tachometer, fuel gauge, oil pressure gauge, temperature gauge. Likely an AM/FM radio with a single speaker. Driver Assistance Driver Assistance Features: None in the modern sense. Driver aids would be limited to the inherent handling characteristics and reliable braking system of the era. 🔧 Maintenance Service Intervals Oil Change Interval Km: Typically every 5,000 - 7,500 km (3,000 - 5,000 miles) or 6-12 months, depending on usage and oil quality. Tune Up Interval Km: Spark plug replacement, ignition timing, and carburetor adjustments typically recommended every 15,000 - 20,000 km (10,000 - 12,000 miles).
