Engine and Performance of the Nissan Sunny III (N14)

Powertrain Overview

At the heart of the Nissan Sunny III (N14) 1.6 16V (110 Hp) model lay a robust and well-engineered internal combustion engine designed for efficiency and durability. This naturally aspirated, inline four-cylinder petrol (gasoline) engine featured a front, transverse layout, typical for front-wheel-drive compact cars of its era. With an engine displacement of 1596 cm³ (approximately 1.6 liters or 97.39 cubic inches), it was a common and well-proven powerplant in Nissan’s lineup.

A key highlight of this engine was its advanced valvetrain for the time: a Double Overhead Camshaft (DOHC) configuration with 16 valves, meaning four valves per cylinder. This setup significantly improved engine breathing compared to older 8-valve or single overhead camshaft designs, allowing for better airflow into and out of the cylinders, which translated directly into improved power output and efficiency. Fuel delivery was managed by a multi-port manifold injection system, a sophisticated method that provided precise fuel metering to each cylinder, optimizing combustion and reducing emissions compared to older carburetor systems.

Performance Characteristics

The 1.6-liter DOHC engine generated a respectable 110 horsepower at 6000 rpm. This power output, coupled with a torque figure of 147 Nm (108.42 lb.-ft.) at 4000 rpm, provided the Nissan Sunny III (N14) with lively performance for its segment. The power-per-liter ratio stood at 68.9 Hp/l, indicating efficient power extraction from its displacement.

The powertrain architecture directed power to the front wheels via a 5-speed manual transmission. This combination offered drivers a direct and engaging driving experience, allowing for optimal control over the engine’s power band. With a curb weight of 1030 kg (2270.76 lbs), the Sunny III (N14) boasted a weight-to-power ratio of 9.4 kg/Hp (or 106.8 Hp per tonne) and a weight-to-torque ratio of 7 kg/Nm (or 142.7 Nm per tonne). These figures underscore the car’s agile nature and capable acceleration for a compact sedan of the early 1990s, making it suitable for both city commuting and longer highway journeys. Its compression ratio of 9.5:1 was also standard for naturally aspirated gasoline engines of that period, balancing performance with fuel economy.

Design and Features

Exterior and Interior Design

The Nissan Sunny III (N14) sedan embodied the design philosophy of the early 1990s: clean lines, functional aesthetics, and a focus on practicality. Its four-door sedan body type offered a traditional and widely accepted silhouette, emphasizing passenger comfort and cargo capacity. The exterior dimensions were compact yet substantial enough to provide a comfortable interior for five occupants. With a length of 4230 mm (166.54 inches), a width of 1690 mm (66.54 inches), and a height of 1395 mm (54.92 inches), the N14 Sunny was easy to maneuver in urban environments while maintaining a stable presence on the road. The wheelbase of 2430 mm (95.67 inches) was optimized for both ride comfort and interior space.

Inside, the Sunny N14 offered a no-nonsense, ergonomically sound cabin. The five-seat configuration provided adequate room for adults, and the materials, while not luxurious, were durable and well-fitted, reflecting Nissan’s commitment to reliability. Practicality was a strong suit, exemplified by a generous trunk (boot) space of 440 liters (15.54 cubic feet), making it highly capable for family errands or road trips. The fuel tank capacity of 50 liters (13.21 US gallons) ensured a decent range between fill-ups.

Chassis, Safety, and Convenience Features

Underneath its unassuming exterior, the Nissan Sunny III (N14) featured a conventional yet competent chassis setup. The front suspension utilized a wishbone design, known for providing good ride comfort and handling stability. The rear suspension employed a spring strut system, a cost-effective and space-efficient solution common in compact cars. Braking power was provided by ventilated discs at the front, offering superior heat dissipation and stopping performance, complemented by drum brakes at the rear.

A significant safety feature for its class and era was the inclusion of ABS (Anti-lock Braking System). In the early 1990s, ABS was still a premium option or reserved for higher-end vehicles, making its presence in the Sunny N14 a testament to Nissan’s focus on progressive safety. Steering was managed by a rack and pinion system, assisted by hydraulic power steering, providing a comfortable and responsive feel to the driver. The car rode on 175/70 R13 tires, a common size for compact cars of the period, balancing grip with ride comfort and affordability. The front and rear tracks of 1445 mm (56.89 inches) and 1430 mm (56.3 inches) respectively contributed to the car’s stable road manners.
