What Changed for 2009:
- Four models continue into 2009, including E320 BlueTec and the E63 AMG
- Sedan and wagon body styles remain available
- Luxury sedans/wagons get new 17-inch, 7-spoke wheels
- AMG Sport package now standard on E350 and E550 Sport sedans
- 4Matic all-wheel drive (AWD) is no-charge option on sedans
- HD Radio and Sirius Real-Time Traffic information now available
The E-Class is Mercedes-Benz's full-size or executive-class model and is built in both sedan and station wagon body styles. The newest generation was introduced in 2003 and was redesigned and updated for the 2007 model year. All E-Class vehicles are equipped with Pre-Safe, a Mercedes safety system also used in the larger, S-Class luxury sedan. Pre-Safe uses various sensors to detect when a crash is imminent and tighten seat belts, properly position the front passenger seat, and automatically close the sunroof and side windows.
Revisions for the 2009 model year primarily include option and equipment changes. The E350 and E550 Sport sedans gain a standard AMG Sport package, including 18-inch, AMG 5-spoke wheels, deeper front/rear aprons, dual exhausts, and a lowered sport suspension. Luxury sedans and wagons ride on new 17-inch, 7-spoke wheels. A new multimedia head unit has a more colorful 6.5-inch display, with in-dash 6-disc CD/DVD changer and Bluetooth hands-free connectivity. New optional features for the COMAND system include an iPod/MP3 interface, HD Radio, Sirius Real-Time Traffic information, and Zagat restaurant ratings, along with a voice-control system for audio, navigation and phone functions. A hard-disk drive can function with the navigation system and store 4 gigabytes of music.
All 2009 Mercedes-Benz E-Class vehicles are covered by a 4-year/50,000-mile warranty with 24-hour roadside assistance.
The Mercedes-Benz E-Class is available for 2009 as the E320 BlueTec sedan, E350 sedan or wagon, E550 sedan, and E63 AMG sedan or wagon. Some models are available with 4Matic AWD, now as a no-charge option. (See powertrain section below for details.) Standard equipment includes a 510-watt, 12-speaker harman/kardon Logic7 surround system with Dolby Digital and DTS 5.1 surround sound.
The E320 BlueTec and E350 sedan are equipped with a glass sunroof; multi-function steering wheel; 10-way, power-adjustable front seats; dual-zone automatic climate controls; remote central locking with Smart Key; power windows; auto-dimming rearview mirrors; electric-adjustable tilt and telescoping steering column; integrated garage door opener; rain-sensing intermittent windshield wipers; and burl walnut wood interior trim.
The E350 wagon adds a rear-facing third-row seat (something not offered by the competition). The E550 sedan adds 4-zone automatic climate controls, leather upholstery and black bird's-eye maple wood trim. The E350 and E550 Sport sedans have white gauges and an AMG steering wheel with manual shift paddles. The E63 AMG sedan and wagon add Sirius satellite radio, AMG heated front seats, AMG Nappa leather, AMG instrumentation with Racetime, and AMG badges. An optional E63 performance package includes an AMG-modified Airmac sport suspension, 2-piece, 19-inch alloy wheels, bigger front brake discs, limited-slip differential, and an Alcantara-wrapped AMG sport steering wheel.
The 2009 Mercedes-Benz E320 BlueTec is equipped with a 3.0-liter V-6 \"Bluetec\" diesel engine that produces 210 hp and 400 lb.-ft. of torque. Linked to a 7-speed automatic transmission, that powertrain runs on the new \"clean\" low-sulfur diesel fuel and is EPA-rated at 23 mpg city/32 mpg highway. The E350 uses a 3.5-liter, gasoline-burning V-6 engine that pumps out 268 hp and 258 lb.-ft. of torque. Like all E-Class vehicles, the E350 has a 7-speed automatic transmission. The rear-wheel-drive (RWD) E350 sedan is rated at 17 mpg city/24 mpg highway. With 4Matic AWD, the E350 sedan is rated at 16 mpg city/22 mpg highway, while the 4Matic wagon gets 16 mpg city/21 mpg highway. The E550 has a 382-hp, 5.5-liter V-8 engine that develops 391 lb.-ft. of torque, enabling it to reach 60 mph in less than 5.5 seconds, according to Mercedes. According to the EPA estimates, this powertrain rates at 15 mpg city/22 mpg highway as a RWD sedan and 13 mpg city/19 mpg highway when combined with 4Matic AWD. The E550 is not available as a wagon.
The E63 AMG has a hand-built, 6.2-liter V-8 engine that pumps out 507 hp and 465 lb.-ft. of torque. Linked to a 7-speed automatic transmission with AMG's SpeedShift technology, the engine propels either the sedan or wagon body to 60 mph in 4.3 seconds with an electronically limited top speed of 155 mph, according to Mercedes-Benz. The fuel consumption of the E63 AMG sedan is rated at 13 mpg city/20 mpg highway. The E63 wagon earns a lower EPA estimate of 13 mpg city/18 mpg highway. Like other AMG models, the E63 AMG has larger brakes and high-performance wheels and tires.
In addition to the Pre-Safe collision-detection system, the 2009 Mercedes-Benz E-Class models are equipped with an Electronic Stability Program, anti-lock brakes with brake assist, and tire-pressure-monitoring systems. They also have front and side air bags for the driver and front-seat occupant. There are side air bags for the second row and curtain air bags that cover all rows.
The National Highway Traffic Safety Administration (NHTSA) rates the E-Class at 4 stars for frontal-impact protection for driver and occupant, 5 stars (the agency's highest rating) for front- and rear-seat side-impact, and 5 stars for resistance to rollover. Those ratings apply to both sedans and wagons. The Insurance Institute for Highway Safety (IIHS) rates the E-Class \"Good\" (the Institute's highest rating) for frontal-impact protection and \"Acceptable\" for side-impact protection.
BlueTec is Mercedes' advanced diesel technology, which optimizes engine performance while minimizing exhaust emissions, the automaker states. Mercedes says the key aspect of BlueTec involves lowering levels of nitrogen oxides in an effective and economical manner. In order to combine all technical solutions for emission reduction into an optimized package, BlueTec uses a multi-staged approach that includes:
- Optimization of engines and combustion processes to reduce engine-out emissions as much as possible. This includes the use of electronic engine control systems, 4-valve technology, third-generation common-rail direct injection with piezo injectors, variable-geometry turbochargers, and exhaust gas recirculation.
- Use of oxidation catalytic converters to minimize emissions of carbon monoxide (CO) and unburned hydrocarbons (HC).
- Use of the particulate filter (which have been standard equipment in all Mercedes-Benz diesel passenger cars in many countries since the summer of 2005). Such filters can cut particulate emissions by up to 98 percent, says Mercedes, resulting in particulate emissions significantly lower than the current EU4 limit of 0.025 grams/kilometer.
- The diesel engine inherently produces higher nitrogen oxides than a gasoline engine. However, BlueTec can reduce nitrogen oxides so efficiently that the vehicle is able to comply with the most stringent exhaust gas limits, says Mercedes. The E320 BlueTec uses a refined NOx storage catalytic converter in combination with an SCR catalytic converter to lower nitrogen oxide emissions.
