The Mercedes-Benz SL (R129) AMG SL 60 V8 Automatic, produced between September 1993 and December 1995, represented the pinnacle of performance for the R129 generation SL roadster during its short production run. Positioned as the flagship model, it offered a substantial upgrade over the standard SL variants, boasting a powerful V8 engine and a sophisticated automatic transmission. The R129 SL, launched in 1989, was a significant departure from its predecessor, the R107, offering increased refinement, improved safety features, and a more modern design. The AMG SL 60 was the most potent version available during this period, catering to buyers seeking uncompromising performance and exclusivity.
Powertrain & Engine Architecture
The heart of the AMG SL 60 is the M119 E 60 engine, a 6.0-liter (5956 cc / 363.46 cu. in.) naturally aspirated V8. This engine, hand-built by AMG, produced 381 horsepower at 5500 rpm and a substantial 580 Nm (427.79 lb-ft) of torque at 3750 rpm. The engine featured a cast iron block with aluminum cylinder heads, utilizing multi-port fuel injection. The valvetrain employed double overhead camshafts (DOHC) with four valves per cylinder, optimizing airflow for increased power output. The compression ratio was set at 10:1. The engine’s longitudinal front-mid layout contributed to balanced weight distribution.
Power was delivered to the rear wheels through a 4-speed automatic transmission, specifically designed to handle the engine’s considerable torque. This transmission wasn’t a standard Mercedes unit; it was reinforced and recalibrated by AMG for quicker shifts and increased durability. While not as technologically advanced as some contemporary transmissions, it provided smooth and reliable operation, complementing the engine’s character. The transmission’s gear ratios were tuned for a balance between acceleration and cruising efficiency.
Engine Specifications
The M119 E 60 engine was a significant engineering achievement for its time. Its large displacement and robust construction ensured longevity and provided a distinctive exhaust note. The engine oil specification required adherence to Mercedes-Benz standards to maintain optimal performance and protect the engine’s internal components.
Driving Characteristics
The AMG SL 60 offered a dramatically different driving experience compared to the standard SL models. Acceleration from 0 to 100 km/h (0-62 mph) was achieved in 5.6 seconds, while 0-60 mph took a calculated 5.3 seconds. The electronically limited top speed of 250 km/h (155.34 mph) underscored its high-performance capabilities. The automatic transmission, while smooth, did introduce a slight loss of responsiveness compared to a manual gearbox. However, the abundance of torque meant that the car felt strong and effortless in most driving situations.
The car’s weight of 1800 kg (3968.32 lbs) was noticeable, but the powerful engine mitigated much of the inertia. The suspension, tuned for both comfort and handling, provided a stable and controlled ride, even at high speeds. The rear-wheel drive configuration contributed to a sporty feel, although it required careful throttle control in wet conditions.
Equipment & Trim Levels
As the range-topping model, the AMG SL 60 came standard with a comprehensive list of features. The interior was typically appointed with high-quality leather upholstery, often in exclusive color combinations. Standard equipment included power-adjustable seats, climate control, a premium sound system, and a leather-wrapped steering wheel. Optional extras included upgraded audio systems, burl walnut trim, and various customization options through the AMG personalization program.
The exterior featured AMG-specific body styling, including unique front and rear bumpers, side skirts, and a rear spoiler. The car also rode on distinctive 8 J x 16 H 2 alloy wheels, shod with 225/55 ZR 16 tires. The overall aesthetic was one of understated elegance and sporting intent.
Chassis & Braking
The R129 SL chassis was a robust monocoque construction, providing a high level of rigidity. The front suspension utilized coil springs, wishbones, and a transverse stabilizer bar, while the rear suspension featured an independent multi-link setup with coil springs and a transverse stabilizer bar. This configuration provided a comfortable ride and precise handling.
Braking duties were handled by ventilated discs on all four wheels, coupled with an Anti-lock Braking System (ABS). The braking system was more than adequate for the car’s performance, providing confident stopping power. The steering system was a cone worm with recirculation balls and hydraulic power assistance, offering a balanced feel and reasonable precision.
Market Reception & Comparison
The AMG SL 60 was generally well-received by automotive critics, who praised its powerful engine, luxurious interior, and overall refinement. However, some critics noted the relatively high price tag and the slightly dated automatic transmission. Compared to the standard SL models (such as the 300SL or 320SL), the AMG SL 60 offered a significant performance advantage, but at a considerable premium. Compared to other high-performance roadsters of the era, such as the Porsche 911, the SL 60 offered a more comfortable and luxurious driving experience, albeit with slightly less outright performance.
Fuel economy was understandably poor for a vehicle of this type, with combined fuel consumption of 11.5 l/100 km (20.5 US mpg / 24.6 UK mpg / 8.7 km/l). Reliability was generally good, although the complexity of the AMG-tuned engine and transmission meant that maintenance costs could be higher than those of the standard SL models. The car met Euro 1 emission standards.
