What Changed for 2008:
- New AMG Sport package for E350 and E550 sedan
- 4Matic all-wheel drive (AWD) available on E350 and E550
The E-Class is Mercedes-Benz 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 sensors use various sensors to detect when a crash is imminent and tighten seat belts, properly position the front passengers seat, and automatically close the sunroof and side windows.
All 2008 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 2008 as the E320 Bluetec sedan, E350 sedan or wagon, E550 sedan or E63 AMG sedan or wagon. Some models are available with 4Matic AWD. (See powertrain section below for details.)
The E320 Bluetec and E350 sedan come with a glass sunroof, harmon/kardon Logic7 digital surround sound system with a 6-disc CD changer and auxiliary input (in the glove box) for MP3 or iPod devices; a multi-functional 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 third-row seat. The E550 sedan adds 4-zone automatic climate controls, leather upholstery and black bird's-eye maple wood trim. The E63 AMG sedan and wagon add Sirius satellite radio, AMG heated front seats, an AMG steering wheel with aluminum shift paddles, AMG Nappa leather, AMG instrumentation with Racetime, and AMG badges.
The 2008 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, the powertrain burns 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. Like all E-Class vehicles, the E350 has a 7-speed automatic transmission. The rear-wheel-drive (RWD) sedan is rated at 17 mpg city/24 mpg highway. With 4Matic AWD, the 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 enables it to reach 60 mph in less than 5.5 seconds. 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. 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 less than 4.5 seconds in Mercedes' own testing. The E63 AMG is rated at 12 mpg city/19 mpg highway, with an electronically limited top speed of 155 mph. Like other AMG models, the E63 AMG gets larger brakes and high-performance wheels and tires.
In addition to Pre-Safe, the 2008 Mercedes-Benz E-Class models come equipped with 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, 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 (out of 5) stars for frontal-impact protection for driver and occupant, 5 stars for front- and rear-seat side-impact, and 5 stars for resistance to rollover. The ratings apply to both sedans and wagons. The Insurance Institute for Highway Safety (IIHS) rates the E-Class \"Good\" for frontal-impact protection and \"Acceptable\" for side-impact protection.
Bluetec is Mercedes' advanced diesel technology that optimizes engine performance while minimizing exhaust emissions, the maker states. Mercedes says the key aspect of the 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 has 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 well that the vehicle can 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.
