The 2014 Mercedes-Benz E250 BlueTEC sedan emerges as a frontrunner in the luxury vehicle segment, particularly for those prioritizing fuel economy without sacrificing performance or sophistication. This model achieves an EPA-estimated 45 miles per gallon on the highway and 28 mpg in city driving, setting a new benchmark for fuel efficiency in its class. Notably, the E250 BlueTEC also marks the introduction of the first diesel E-Class equipped with optional 4MATIC all-wheel drive, maintaining impressive figures of 42 mpg highway and 27 mpg city even with AWD. This positions the Mercedes-Benz E250 BlueTEC as the leading choice for drivers seeking exceptional mileage in a diesel sedan.
Cutting-Edge Four-Cylinder Engine with Smooth Operation
At the heart of the 2014 E250 BlueTEC lies a state-of-the-art, high-efficiency turbodiesel engine. This all-aluminum, in-line four-cylinder powerhouse incorporates four valves per cylinder and dual overhead camshafts with variable valve timing, delivering 195 horsepower and a robust 369 lb-ft of torque. To counteract the inherent vibrations of an in-line four-cylinder configuration, Mercedes-Benz engineers have integrated two Lanchester balance shafts. These shafts, spinning at twice the crankshaft speed on low-friction roller bearings, ensure remarkably smooth engine operation. Drivers will immediately appreciate the benefits of the two-stage turbocharging system, which eliminates turbo lag, provides instant throttle response, and generates a broad torque curve across the entire RPM range, resulting in noticeably enhanced performance. The readily available 369 lb-ft of torque at just 1,800 rpm further emphasizes the engine’s responsiveness and driving pleasure.
BlueTEC Technology: Advanced Diesel Engineering
The BlueTEC direct fuel injection system in the E250 BlueTEC operates at an astounding 2,000 bar (28,400 psi). This extremely high fuel pressure optimizes power output and minimizes exhaust emissions. The increased injection pressure enables the four piezo injectors to make ultra-precise fuel adjustments in response to changes in engine load and speed. This sophisticated system positions the four-cylinder diesel engine at the forefront of passenger vehicle diesel technology, offering both performance and environmental responsibility.
AdBlue Injection for Emission Control
To meet stringent emission standards across all 50 U.S. states, the Mercedes-Benz E250 BlueTEC employs the BlueTEC system with AdBlue injection. This technology ensures the diesel engine’s emissions are as clean as a modern gasoline engine. AdBlue, a water-based urea solution, is stored in a dedicated tank and precisely injected into the exhaust stream in small quantities. Conveniently refilled through the fuel filler door during routine maintenance, AdBlue plays a crucial role in reducing nitrogen oxides. When injected into the pre-cleaned exhaust gas, AdBlue releases ammonia (NH3), which then converts harmful nitrogen oxides into harmless nitrogen and water within a downstream catalytic converter. This Selective Catalytic Reduction (SCR) process represents the most effective exhaust gas after-treatment method currently available, highlighting Mercedes-Benz’s commitment to clean diesel technology in the E250 BlueTEC.
4MATIC All-Wheel Drive: Enhanced Stability and Traction
The optional 4MATIC all-wheel-drive system available on the Mercedes-Benz E250 BlueTEC provides enhanced stability and traction in diverse driving conditions. As all-wheel-drive technology evolves, it gains popularity, particularly in the luxury car market, for its safety and handling benefits. The Mercedes-Benz 4MATIC system integrates seamlessly with the 7-speed automatic transmission, fitting within the standard E-Class body and utilizing the existing front suspension architecture. Innovative design measures minimize energy loss within the system, resulting in negligible impact on fuel efficiency. Mercedes-Benz anticipates a balanced adoption rate of around 50/50 between rear-wheel drive and 4MATIC versions of the E250 BlueTEC nationwide, with higher uptake of 4MATIC in regions with colder climates where all-wheel drive is highly valued for winter driving.
Intelligent Drive: Leading in Active and Passive Safety
Mercedes-Benz prioritizes real-world safety and aims for accident-free driving. The E-Class embodies this commitment with over 30 standard and optional active and passive safety systems under the umbrella of Mercedes-Benz Intelligent Drive. The Driver Assistance Package, an available option, further enhances safety with features like:
- DISTRONIC PLUS with Steering Assist: Adaptive cruise control with semi-autonomous steering, operational from standstill up to 124 mph, adapting to varying road conditions.
- PRE-SAFE Brake with pedestrian detection: Utilizes radar and stereo cameras to detect vehicles and pedestrians ahead, providing braking assistance and initiating full braking when necessary.
- PRE-SAFE PLUS: Rear-facing radar anticipates rear-end collisions, preparing the vehicle to mitigate passenger injury risk.
- BAS PLUS with Cross Traffic Assist: Stereo cameras detect cross-traffic situations and provide appropriate brake support.
- Active Lane Keeping Assist and Active Blind Spot Protection: Corrective one-sided braking assists in maintaining lane position and avoiding blind spot collisions.
These advanced safety technologies underscore Mercedes-Benz’s dedication to driver and passenger well-being in the E250 BlueTEC.
