Sport Utility Vehicle - Designs

Designs

Although designs vary, SUVs have historically been mid-size passenger vehicles with a body-on-frame chassis similar to that found on light trucks. Early SUVs were mostly two-door models, and were available with removable tops. However, consumer demand pushed the SUV market towards four doors, by 2002 all full-size two-door SUVs were gone from the market. Two-door SUVs were mostly carry-over models, and their sales were not viable enough to warrant a redesign at the end of their design cycle. The Jeep Wrangler remained as a compact two-door body style, although it was also joined by a four-door variant starting with the 2007 model year, the Wrangler Unlimited. The number of two-door SUV models increased in the 2010s with the release of the Range Rover Evoque and the Nissan Murano convertible, although both vehicles are unibody.

Most SUVs are designed with an engine compartment, a combined passenger and cargo compartment, and no dedicated trunk such as in a station wagon body. Most mid-size and full-size SUVs have three rows of seats with a cargo area directly behind the last row of seats. Cargo barriers are often fitted to the cargo area to protect the vehicles occupants from injury from unsecured cargo in the event of sudden deceleration or collision.

SUVs are known for high ground clearance, upright, boxy body, and high H-point. This can make them more likely to roll over due to their high center of gravity. Bodies of SUVs have recently become more aerodynamic, but the sheer size and weight keeps their fuel economy poor.
