2025 Kia Carnival vs. 2025 Toyota Sienna: Which Minivan is the Better?

Both the 2025 Kia Carnival and the 2025 Toyota Sienna are highly sought-after minivans, and while they share similarities in size and utility, there are key differences that set them apart. Here’s a detailed comparison of the two models based on their performance, design, features, and overall value for consumers.

 

Performance and Engine Options

  • 2025 Kia Carnival: The Carnival retains its powerful 3.5L V6 engine, which produces 290 horsepower and 262 lb-ft of torque. It offers a strong driving experience, especially for those who prioritize power in their minivan. Additionally, Kia has introduced a hybrid option for 2025. This hybrid Carnival features a 1.6L turbocharged engine paired with an electric motor, producing a combined 242 horsepower and 271 lb-ft of torque. While the hybrid model prioritizes fuel efficiency, it still maintains respectable performance levels.
  • 2025 Toyota Sienna: The 2025 Toyota Sienna continues to offer only one powertrain, a 2.5L 4-cylinder hybrid that generates 245 horsepower. While this engine may lack the punch of the Carnival’s V6, it excels in fuel efficiency. The Sienna is estimated to achieve 6.5 L/100 km, which is significantly better than the gas-powered Carnival’s efficiency. Furthermore, the Sienna offers all-wheel drive (AWD) as an option, an appealing feature for Canadian buyers facing harsh winter conditions​.

Interior and Space

  • 2025 Kia Carnival: One of the Carnival’s strongest selling points is its spacious interior. The 2025 model offers up to 168.2 cubic feet of passenger space, and when the third-row seats are folded, it provides up to 145.1 cubic feet of cargo capacity. Additionally, Kia has introduced luxurious VIP Lounge seats in the second row, with reclining seats and leg rests, offering an experience akin to first-class travel​.
  • 2025 Toyota Sienna: The Sienna offers slightly less space, with a total of 162.5 cubic feet for passengers and 101 cubic feet of maximum cargo capacity. While it isn’t as spacious as the Carnival, the Sienna’s interior remains functional and comfortable, with flexible seating configurations for families. The Sienna offers captain’s chairs in the second row as well, though without the premium lounge features found in the Carnival​.

Technology and Features

  • 2025 Kia Carnival: The Carnival comes well-equipped with advanced technology features, including a 12.3-inch touchscreen infotainment system, wireless Apple CarPlay and Android Auto, and a host of driver-assistance features such as blind-spot monitoring, forward-collision warning, and lane-keeping assist. Kia’s commitment to tech and convenience makes it an excellent option for tech-savvy families.
  • 2025 Toyota Sienna: The Sienna also boasts modern tech features, including a 9-inch infotainment touchscreen, Apple CarPlay, Android Auto, and an array of driver assistance technologies. However, the Sienna’s technology suite is not as comprehensive or luxurious as the Carnival’s. Nevertheless, it includes crucial safety features like adaptive cruise control, pedestrian detection, and lane-keeping systems​.

Fuel Efficiency and Driving Dynamics

  • Kia Carnival: The standard V6 engine provides good acceleration and power, but it lacks the fuel economy benefits of the Sienna. The hybrid Carnival improves on this, but still doesn’t reach the fuel efficiency levels of the Sienna hybrid, making the gas Carnival less ideal for those looking to minimize fuel consumption​.
  • Toyota Sienna: The hybrid-only powertrain means excellent fuel economy, especially for long-distance family road trips. The Sienna’s combined rating of 6.5 L/100 km far surpasses the Carnival’s V6 version. Moreover, with available AWD, the Sienna is better suited for all-weather driving.

Pricing and Value

  • Kia Carnival: The 2025 Kia Carnival starts at approximately $43,280 CAD for the standard gas model, with the hybrid model priced higher. Given its strong powertrain and luxurious features, it offers great value for larger families looking for comfort and space​.
  • Toyota Sienna: The 2025 Sienna is priced around $44,950 CAD, slightly more expensive than the base Carnival. However, its superior fuel economy, hybrid system, and optional AWD make it a compelling option for eco-conscious families​.

Conclusion

The 2025 Kia Carnival is the best choice for those seeking a more powerful engine, greater interior space, and premium second-row seating for added comfort. However, if fuel efficiency and all-wheel-drive capability are your priorities, the 2025 Toyota Sienna is the better option, especially for Canadian winters. Both models offer excellent family-friendly features, so the decision largely depends on your driving needs and priorities.
