Engine Specifications
The engine options for the 2013 E-Class coupes and cabriolets are key to understanding their performance and maintenance needs. The E350 models are equipped with a 60-degree V6 engine featuring a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder. This naturally aspirated, direct-injection engine has a displacement of 3,498 cc, with a bore of 3.66 inches and a stroke of 3.39 inches, and a compression ratio of 12.0:1. It delivers 302 horsepower at 6,500 rpm and 273 lb-ft of torque between 3,500 and 5,250 rpm, reaching a maximum engine speed of 7,000 rpm.
In contrast, the more powerful E550 variants boast a 90-degree V8 engine, also with a DOHC valvetrain and four valves per cylinder. Constructed with an aluminum block and heads, this engine displaces 4,663 cc. It features direct gasoline injection with piezo injectors and twin turbochargers, operating at 12.9 lbs of boost. The bore and stroke are the same as the V6 at 3.66 and 3.39 inches respectively, but the compression ratio is a lower 10.5:1, optimized for forced induction. This V8 produces 402 horsepower between 5,000 and 5,750 rpm and a substantial 443 lb-ft of torque from 1,600 to 4,750 rpm. The E550’s maximum engine speed is 6,300 rpm.
Transmission and Drivetrain
All 2013 Mercedes-Benz E-Class coupe and cabriolet models utilize a seven-speed automatic transmission with Touch Shift manual shift control. The gear ratios are consistent across all models, with ratios from 4.38:1 in first gear to 0.73:1 in seventh gear, and a reverse gear ratio of -3.42:1. A “comfort mode” reverse gear (R2) operates at -2.231. The final drive ratio is 2.82:1 for E350 models and 2.65:1 for E550 models, reflecting the different torque characteristics of the engines. The E350 4MATIC model features all-wheel drive, enhancing traction and stability in varied driving conditions.
Chassis, Suspension, and Brakes
The suspension system in the 2013 E-Class is designed for both comfort and handling. All models are equipped with AGILITY CONTROL suspension, featuring a stroke-dependent damping system. The E550 Cabriolet upgrades to a dynamic handling suspension with continuously variable damping. Both front and rear suspensions are independent, utilizing stabilizer bars. Steering is power-assisted, speed-sensitive rack-and-pinion, with a 14.7:1 steering ratio and 3 turns lock-to-lock, resulting in a turning radius of 35.3 inches.
Braking systems are robust, featuring dual-circuit, power-assisted four-wheel discs with ABS and Brake Assist. The E350 models have front disc diameters of 12.7 inches and rear discs of 11.8 inches. The E550 models upgrade to larger 14.2-inch front discs while retaining 11.8-inch rear discs, reflecting their higher performance capabilities.

Dimensions and Capacities
The exterior dimensions are uniform across coupe and cabriolet models, with a wheelbase of 108.7 inches, a length of 185 inches, and a width of 70.3 inches. Height varies slightly, with coupes at 54.8 inches and the cabriolet at 55.0 inches. Ground clearance is consistent at 3.0 inches. Interior dimensions offer front headroom of 36.8 inches in coupes and 38.3 inches in the cabriolet, and front legroom of 42.0 inches across all models. Cargo volume is 13.3 cubic feet in coupes and 11.5 cubic feet in the cabriolet (8.8 cu. ft. with the top down). Fuel tank capacity is 17.4 gallons with a 4.6-gallon reserve.
Performance Metrics
Performance varies between models, with 0-60 mph times of 6.1 seconds for E350 models and a quicker 4.9 seconds for E550 models. Top speed is electronically limited to 130 mph for all variants. Fuel economy differs, with the E350 models achieving around 17 mpg city / 24 mpg highway / 20 mpg combined, while the E550 models are slightly less efficient at 17 mpg city / 27 mpg highway / 21 mpg combined for the coupe and 16 mpg city / 25 mpg highway / 19 mpg combined for the cabriolet.
Understanding these detailed specifications of the 2013 Mercedes-Benz E-Class is essential for automotive service professionals. From engine mechanics to chassis specialists, these data points provide a solid foundation for accurate diagnostics and effective repair strategies, ensuring optimal performance and longevity for these luxury vehicles.
