Price and Value
The V6 Carnival is the budget pick at $37,490. Hybrid to hybrid, the Carnival LXS and Sienna LE start within $170 of each other. The Carnival's hands-free power sliding doors are standard on every trim; on the Sienna, the LE has power sliding doors and the XLE and up add hands-free operation.
At the top, the Carnival Hybrid SX Prestige ($53,590) is $5,120 less than a Sienna Platinum and offers leather, a head-up display, VIP lounge seats and an available rear-seat entertainment system with dual 14.6-in. screens.
Fuel Economy and Power
Toyota's hybrid is the efficiency champ: 36 mpg combined with FWD and 35 with AWD, versus 33 for the Carnival Hybrid. Power is close (242 vs. 245 hp), and Kia's turbo hybrid makes 271 lb-ft of torque, which Kia rates best in class.
If you'd rather have the V6, the gas Carnival makes 287 hp and tows 3,500 lbs, but it's rated 21 mpg combined.
Space and Seating
The Carnival is the better cargo hauler. Its 40.2 cu ft behind the third row beats the Sienna's 33.5, and because its second-row seats can be removed, it has 145.1 cu ft of max cargo space versus 101. The Sienna's second row slides but stays in.
The Sienna has the roomier third row, with 38.7 in. of legroom versus 35.6, and its captain's chairs slide extra-long; Limited and Platinum add ottomans. The Carnival SX Prestige offers powered VIP lounge seats with leg rests, heating and ventilation. Compare seating on the Carnival page.
Colorado Driving
- AWD: the Sienna's big advantage. Its electric AWD is available on every trim and standard on the Woodland and Platinum. Every Carnival is FWD, so winter tires matter.
- Clearance: 6.8 in. on the Carnival, slightly more than the Sienna's 6.4 in. (7.0 on the Woodland).
- Towing: 3,500 lbs for the Sienna and the V6 Carnival; 2,500 for the Carnival Hybrid.
