Revised styling, new engines, and additional safety equipment highlight 2007 for Mercedes' midsize sedans and wagons. The E-Class line comes in rear- and all-wheel drive versions. Four models are offered. E350s have a 268-hp 3.5-liter V6. The E550 has a 382-hp V8 and replaces the 302-hp E500. The E320 Bluetec has a 208-hp V6 turbodiesel and replaces the 201-hp E320 CDI. The high-performance E63 has a 507-hp V8 and replaces the 469-hp E55.

All E-Class models are available as sedans; the E350 and E63 are also available as wagons. Mercedes' 4Matic AWD is available on E350 and E550. All rear-drive models have a 7-speed automatic transmission; E63 adds manual-shift steering wheel buttons. AWD models have a 5-speed automatic. ABS and traction/antiskid control are standard. An air suspension with driver-adjustable shock absorbers is standard on E550 and E63.

Front and rear side airbags and curtain side airbags with rollover deployment are standard. New for '07 is Mercedes' Pre-Safe system, which automatically tightens seatbelts and readies full braking power when sensors detect an imminent collision.

A no-cost option for E350 and E550 is a Sport package that includes lowered suspension, 18-inch wheels, and unique trim. Other options include steering-linked bi-xenon headlamps and adaptive cruise control. Also available: a wireless cell phone link, navigation system, heated/cooled front seats, and keyless access and starting. Rear obstacle detection is available for sedans. So is Mercedes' full-length Panorama glass roof with a power tilt/slide panel above the front seats. The E63 has sport suspension, exhaust, and seats. All '07 E-Class models get revised front and rear styling.
