1985-1989 Mercedes-Benz SL (R107 facelift ) 560 SL CAT V8 (230 Hp) Automatic

The Mercedes-Benz SL (R107) 560 SL, produced from June 1985 to August 1989, represents the pinnacle of the R107 series, a generation renowned for its blend of luxury, performance, and enduring design. This facelifted version, often referred to as the “California” model due to its focus on the US market, featured significant updates including smoother body lines and improved emissions control. The 560 SL, equipped with the M117 V8 engine and automatic transmission, was the top-of-the-line offering, positioned as the premium variant within the R107 range, above the 300SL and 420SL.

The heart of the 560 SL is the M117 E 56 5.5-liter V8 engine, internally designated as 117.967. This engine utilized multi-port fuel injection, a system that precisely delivers fuel to each cylinder for optimal combustion. The engine features a single overhead camshaft (SOHC) valvetrain operating two valves per cylinder. The 560 SL’s engine produced 230 horsepower at 4750 rpm and 373 Nm (275.11 lb-ft) of torque at 3250 rpm. This power was delivered through a four-speed automatic transmission, designed for smooth and comfortable cruising. The transmission’s gear ratios were optimized for both acceleration and highway efficiency, though it wasn’t designed for particularly aggressive shifting.

Driving the 560 SL offered a distinctly grand touring experience. While not a sports car in the modern sense, the V8 engine provided ample power for confident acceleration – 0 to 60 mph in approximately 7.3 seconds and a top speed of 138.57 mph. The automatic transmission, while smooth, did result in some power loss compared to the available manual transmission options in earlier R107 models. The focus was on relaxed, effortless performance, making it ideal for long-distance journeys. The weight-to-power ratio of 7.5 kg/hp contributed to a feeling of substantial solidity and stability on the road.

The 560 SL came standard with a comprehensive list of features befitting its flagship status. Interiors were typically trimmed with leather upholstery, and featured wood veneer accents on the dashboard and door panels. Standard equipment included power windows, power steering, air conditioning, and an AM/FM stereo. Optional extras included a sunroof, heated seats, and a more sophisticated audio system. The dashboard layout was classic Mercedes-Benz of the era, prioritizing functionality and a sense of understated elegance.

The chassis of the 560 SL featured a double wishbone suspension at the front, providing a comfortable ride and predictable handling. The rear suspension utilized a threaded twist beam, a cost-effective solution that offered a reasonable balance between comfort and stability. Braking duties were handled by ventilated discs at the front and solid discs at the rear, supplemented by an Anti-lock Braking System (ABS) for enhanced safety. The steering system was a cone worm with recirculation balls, providing a relatively heavy but precise steering feel. The 560 SL rode on 7J x 15 inch wheels, fitted with 205/65 R15 tires.

Contemporary reviews of the 560 SL generally praised its luxurious interior, smooth ride, and powerful engine. However, some critics noted the car’s considerable weight and the automatic transmission’s tendency to prioritize comfort over outright performance. Fuel economy, while acceptable for a V8 of this era, was not a strong point. Compared to the 300SL and 420SL, the 560 SL offered significantly more power and a more refined driving experience, but at a higher price point. Reliability was generally good, though the complexity of the M117 engine and its associated systems meant that maintenance could be expensive.

Today, the 560 SL remains a highly sought-after classic. The M117 engine, while complex, is known for its durability when properly maintained. Finding well-preserved examples can be challenging, as many have been used as daily drivers and may require significant restoration work. However, the 560 SL’s combination of timeless styling, robust engineering, and comfortable driving experience ensures its continued appeal to collectors and enthusiasts alike. Its status as the ultimate R107 variant contributes to its enduring value in the used car market.
