The Mercedes-Benz E 350 CGI T-modell (S211 facelift), produced from 2006 to 2009, represented a significant evolution of the popular E-Class wagon. Positioned as a premium offering within the S211 range, it combined a high-output 3.5-liter V6 engine with the sophisticated 7G-TRONIC automatic transmission. This variant aimed to deliver a blend of performance, luxury, and practicality for buyers seeking a refined estate car experience. The “CGI” designation denoted the use of direct fuel injection, a technology Mercedes-Benz employed to enhance both power and efficiency. It sat above the E 320 CDI and E 280 models in terms of performance, but below the higher-performance AMG variants.

Powertrain & Engine Architecture
The heart of the E 350 CGI T-modell was the M272.985 3.5-liter V6 engine. This engine featured a 60-degree V-angle and employed a sophisticated direct injection system, branded as CGI (Compressed Ignition). Direct injection allowed for more precise fuel delivery, resulting in improved combustion efficiency and increased power output. The engine utilized a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder, further enhancing its breathing capabilities. The M272 engine family was known for its smooth operation and relatively high power density. Paired with this engine was the 7G-TRONIC seven-speed automatic transmission. This transmission offered a wide range of gear ratios, contributing to both fuel efficiency and responsive acceleration. The 7G-TRONIC featured a torque converter lock-up clutch that engaged in most gears, minimizing slippage and improving efficiency.
Driving Characteristics
The E 350 CGI T-modell offered a refined and comfortable driving experience. The 292 horsepower and 365 Nm (269 lb-ft) of torque provided ample power for everyday driving and confident overtaking maneuvers. While not a sports car, the combination of the V6 engine and the 7G-TRONIC transmission delivered a 0-60 mph time of around 6.7 seconds. The 7G-TRONIC’s close gear ratios kept the engine in its optimal power band, providing smooth and seamless acceleration. Compared to the E 320 CDI, the E 350 CGI offered noticeably quicker acceleration and a more responsive feel. However, the diesel variant provided superior fuel economy. The E 350 CGI also felt more agile than the heavier, more basic E-Class wagons.
Equipment & Trim Levels
The E 350 CGI T-modell typically came well-equipped as a premium variant. Standard features often included leather upholstery, automatic climate control, a premium audio system, and power-adjustable front seats. Optional extras included a sunroof, navigation system, upgraded wheels, and advanced safety features like Distronic adaptive cruise control. Interior trim options ranged from wood veneers to aluminum accents, allowing buyers to personalize the cabin. The wagon’s rear seats could be folded down to expand cargo capacity, and a self-leveling suspension system was often included to maintain a consistent ride height even when heavily loaded.
Chassis & Braking
The S211 E-Class wagon featured a robust chassis with a double wishbone front suspension and an independent multi-link rear suspension. This suspension setup provided a comfortable ride while maintaining good handling characteristics. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering. The E 350 CGI typically came equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) and electronic brake-force distribution (EBD) were standard safety features.
Market Reception & Comparison
The E 350 CGI T-modell was generally well-received by automotive critics. It was praised for its powerful engine, refined ride, and spacious interior. However, some reviewers noted that the fuel economy, while improved by the CGI technology, was still relatively high compared to diesel alternatives. Compared to the E 320 CDI, the E 350 CGI offered a more engaging driving experience but at the cost of fuel efficiency. Against competitors like the BMW 5 Series Touring and Audi A6 Avant, the E 350 CGI offered a compelling combination of luxury, performance, and practicality.
Legacy
The M272 engine family, including the 3.5-liter variant found in the E 350 CGI, has proven to be relatively reliable, although preventative maintenance is crucial. Common issues include oil leaks from the valve cover gaskets and potential problems with the balance shaft. The 7G-TRONIC transmission is generally durable, but fluid changes should be performed at the recommended intervals. Today, the E 350 CGI T-modell represents a well-rounded and capable estate car. Well-maintained examples are sought after by enthusiasts who appreciate its blend of performance, luxury, and practicality. Its relative rarity compared to the diesel models can contribute to higher resale values.
