Renault Samsung SM5 I 518i (132 Hp)

The Renault Samsung SM5 I 518i (132 Hp) represents a significant chapter in the history of the South Korean automotive industry, marking the entry of Renault into the market through its acquisition of Samsung Motors. Launched in 1998, the first-generation SM5 was a mid-size sedan designed primarily for the discerning South Korean domestic market, where it quickly established a reputation for reliability, comfort, and robust engineering. This vehicle was not an original Renault design but rather a rebadged and localized version of the Nissan Cefiro (A32 generation), also known as the Nissan Maxima in some international markets. This strategic move allowed Renault Samsung to leverage Nissan’s well-regarded platforms and powertrains, offering a product that combined Japanese engineering prowess with a localized brand identity. The SM5 I was positioned as a premium yet accessible family sedan, competing in a highly competitive segment with established Korean players. Its production run from 1998 to 2005 saw it become a familiar sight on Korean roads, embodying a blend of international engineering and domestic market sensibilities.

The Renault Samsung SM5 I 518i (132 Hp): Powertrain and Dynamic Performance

At the heart of the Renault Samsung SM5 I 518i (132 Hp) lies a robust and well-proven 1.8-liter (1838 cm³ or 112.16 cu. in.) naturally aspirated inline-four gasoline engine. This powertrain, a testament to Nissan’s engineering legacy, was designed for smooth operation and dependable performance rather than outright speed. The engine layout is a front, transverse configuration, driving the front wheels, a common and efficient setup for mid-size sedans of this era. With a power output of 132 horsepower delivered at a relatively high 6200 rpm, the 518i engine provided adequate motivation for the SM5’s dimensions and weight. The torque figure stands at 119.49 lb.-ft. (162 Nm) peaking at 4800 rpm, indicating a powerplant that prefers to rev to extract its full potential, characteristic of many naturally aspirated engines from the late 20th century. This power delivery profile, coupled with a commendable power per liter ratio of 71.8 Hp/l, ensured responsive acceleration in urban driving and comfortable cruising on highways.

The engine’s technical specifications further underscore its design for longevity and efficiency. It features a Double Overhead Camshaft (DOHC) valvetrain with four valves per cylinder, optimizing airflow for better combustion and higher power output compared to simpler two-valve designs. Fuel is delivered via a multi-port manifold injection system, a standard and reliable method for precise fuel metering. With a compression ratio of 10:1, the engine was designed to run efficiently on standard gasoline. The cylinder bore of 3.25 inches (82.5 mm) and piston stroke of 3.39 inches (86 mm) suggest a slightly undersquare design, contributing to a good balance of torque and horsepower characteristics. Mated to a 5-speed manual transmission, the driver had direct control over the engine’s output, allowing for optimal gear selection to suit varying driving conditions. This combination yielded a respectable maximum speed of 117.44 mph (189 km/h), making the SM5 I 518i a capable performer for everyday driving and longer journeys. The car’s weight-to-power ratio of 10 kg/Hp and a weight-to-torque ratio of 8.1 kg/Nm further illustrate its balanced engineering, prioritizing smooth, predictable dynamics over aggressive sportiness.

Design Philosophy and Features of the Renault Samsung SM5 I

The design of the Renault Samsung SM5 I is a reflection of its origins and its target market. As a four-door, five-seat sedan, its aesthetic prioritizes understated elegance and timeless appeal, typical of the Nissan Cefiro/Maxima A32 it was based upon. The exterior lines are clean and conventional, avoiding flamboyant styling cues in favor of a mature and executive presence that resonated well with Korean consumers. Measuring 189.96 inches (4825 mm) in length, 69.88 inches (1775 mm) in width, and 55.71 inches (1415 mm) in height, the SM5 I occupied a substantial footprint on the road, contributing to a sense of solidity and passenger comfort. The generous 106.3-inch (2700 mm) wheelbase was a key factor in providing ample interior space for both front and rear occupants, a crucial consideration for a family-oriented sedan.

Inside, the SM5 I focused on practicality and ergonomic design. While specific luxury features varied by trim, the general cabin philosophy emphasized durable materials and intuitive controls. The spacious interior was complemented by a substantial trunk capacity of 15.54 cu. ft. (440 liters), making it well-suited for family trips or business use. The vehicle’s kerb weight of 2910.1 lbs. (1320 kg) and a maximum permissible weight of 3880.14 lbs. (1760 kg) highlight its robust construction, capable of carrying a significant payload of 970.03 lbs. (440 kg). The fuel tank capacity of 17.17 US gallons (65 liters) provided a decent range, reducing the frequency of fuel stops.

In terms of chassis and handling, the SM5 I was engineered for a comfortable and composed ride. It featured a wishbone front suspension system, renowned for its ability to provide precise wheel control and absorb road imperfections effectively. The rear suspension employed coil springs, contributing to a smooth ride quality that was a hallmark of the Cefiro platform. Braking performance was handled by ventilated discs at the front and solid discs at the rear, offering reliable stopping power. The steering system utilized a rack and pinion setup, enhanced by hydraulic power steering, ensuring light and responsive steering effort, particularly beneficial in urban maneuvering. The car was fitted with 195/65 R15 H tires on 15-inch wheel rims, a common specification for mid-size sedans of its era, balancing grip, comfort, and rolling resistance. Overall, the Renault Samsung SM5 I offered a well-rounded package, blending dependable performance with a comfortable and practical design, making it a compelling choice in its market segment.
