Engine, Transmission, and Performance Under the Grand Caravan’s stubby hood is a 3.6-liter V-6 engine churning out 283 hp. It has a lively feel, yet the Grand Caravan returned a slower zero-to-60-mph time than its competitors. The six-speed automatic transmission, although never abrupt, is hesitant to downshift for extra passing power. The Grand Caravan blends acceptable cornering capability with a comfortable ride. The suspension soaks up most highway bumps just fine, while larger ones do cause some jolts to shudder through the cabin, Interior, Comfort, and Cargo If the Grand Caravan’s plasticky cabin trim and uninspired interior design seem outdated, that’s because they are; the van was last redesigned in 2008. A high seating position provides a clear view forward, but passenger space is no match for the Grand Caravan’s more modern rivals. As far as cargo space goes, the Grand Caravan doesn’t quite measure up to its rivals; the Toyota Sienna is the winner of the cargo game. Even so, 140 cubic feet is still voluminous, and the Grand Caravan has adequate small-item storage spots.
