Minivan Comparison | Sienna vs Odyssey vs Pacifica vs Sedona

The minivan segment is fresher than it's been in years, possibly decades. The 2021 Toyota Sienna is a completely redesigned model with a bold new look and standard hybrid powertrain. Both the Honda Odyssey and Chrysler Pacifica were refreshed for 2021 with updated styling, upgraded tech, and in the case of the Pacifica, newly optional all-wheel drive. Only the 2021 Kia Sedona soldiers on without changes; it's still a solid van despite its advanced age and relatively few people buying it.  Usually when we put a comparison like this together, we have to pick and choose which vehicles to include (mostly because we can't do some 15-car spreadsheet without utilizing 4-point font). In the case of minivans, there are only four. That certainly makes it easier to research and cross-shop in person without worrying that you might be missing out on something. It also makes it a bit easier to go beyond the usual spreadsheet and dig a little deeper than normal into the competitors. Let's take a brief look at each. 2021 Toyota Sienna The Sienna is completely new for '21 after going a decade with only updates. Its exterior style is more expressive than before, but it's the new cabin that really impresses — it's far more car-like in appearance, but still offers the expected amount of abundant storage and functionality. Mechanically, the big news is that every Sienna is now a hybrid. Though down a bit on power compared to everything else, its 36 mpg combined (or 35 mpg with all-wheel drive) crushes everything but the Pacifica plug-in hybrid. This exceptional fuel economy and its far-sliding, big-kid-friendly second-row seats are its main selling points, but in every other respect, it's fully competitive.  Read our full 2021 Sienna Review 2021 Toyota Sienna View 41 Photos 2021 Chrysler Pacifica The Pacifica gets its first comprehensive set of upgrades since it was all-new for '17. The front end has been restyled, all-wheel drive is now an option and there's a new Pinnacle range-topping trim. The big news, however, is its technology offerings. Every Pacifica now comes standard, as the Odyssey and Sienna do, with a comprehensive array of driver assistance technologies. Every trim also gets Chrysler's latest UConnect infotainment system with a larger, 10.1-inch touchscreen and wireless Apple CarPlay and Android Auto.

Hyundai CVVD engine brings another dimension to valve timing

A new technology from Hyundai Motor Group places another marker on the march to more efficient internal combustion engines. Called Continuously Variable Valve Duration, the innovation permits two options for how long the intake valves remain open during the combustion cycle. The feature adds a third take on valve chicanery, atop variable valve timing that changes when valves open, and variable valve lift that changes how far valves open. Hyundai says the feature returns a 4% improvement in performance, a 5% increase in fuel economy, and lowers emissions by 12%. Hyundai applied for two patents on the valvetrain process in South Korea in 2011 and again in 2015. The altered valve duration in this latest iteration is made possible by two movable arms inside the camshaft. Each arm is anchored at its base to a pin at the center of the camshaft, while the end of each arm extends toward the edge of the camshaft. Changing the position of the pin in the center of the camshaft changes the angle of the arms relative to one another, which moves the camshaft along its mounting rod. Voila, a new intake cam profile that either lengthens or shortens valve overlap.   During low-speed spells at low load, CVVD opens the intake valve from the middle to the end of compression stroke. The weaker detonation isn't a factor at low load, and the reduced friction during compression improves fuel economy. During heavy engine loads, the intake valve closes at the beginning of the compression stroke to maximize the amount of air mixed for detonation, boosting torque. Four additional features enhance the benefits of CVVD. A more powerful direct injection system increases fuel spray pressure from 250 bar to 350 bar. Hyundai doesn't go into details on its Integrated Thermal Management System, but says the ITMS "quickly heats or cools the engine to the optimal temperature." Low-friction components lower overall engine friction by 34 percent. And a low-pressure exhaust gas recirculation layout diverts low-pressure exhaust gas from the traditional EGR route to the turbocharger compressor under high load for better fuel efficiency.   The first engine to boast the new tech is the Smartstream G1.6 T-GDi four-cylinder, which produces 180 horsepower and 195 pound-feet of torque. It will appear in the 2020 Hyundai Sonata Turbo going on sale in South Korea later this year.
