What are the differences between Sienna and Previa?

[McJohnny]

The differences between Sienna and Previa: 1. Different dimensions: Sienna measures 5085mm, 1983mm, and 1811mm; Previa measures 4795mm, 1800mm, and 1750mm. 2. Different engines: Sienna is equipped with a 2.7L naturally aspirated engine and a 3.5L naturally aspirated engine; Previa is equipped with a 2.4L naturally aspirated engine and a 3.5L naturally aspirated engine. Sienna's exterior adopts the OneMotionStyle integrated design, with a bullet-shaped front face, simple and smooth body lines, and a stylish and grand appearance. Its over-five-meter-long body combined with a low center of gravity creates a strong visual effect. Previa's exterior design is bold and avant-garde, with rounded body lines subtly revealing a strong and dynamic style. The uniquely designed headlights connected to the radiator grille give it a spirited and full appearance.

I recently helped a relative choose a car and carefully compared the Sienna and the Previa. The Sienna is Toyota's current star MPV, with a reasonable space layout and comfortable third-row seating, making it ideal for family trips. The hybrid version is particularly fuel-efficient, averaging around 7L per 100km in city driving. The Previa is an older model from the 1990s, with a uniquely designed engine placed under the seats, resulting in noticeable vibrations and noise. It's mostly discontinued now and only available as a used car. In terms of maintenance, the Sienna is newer and more reliable, equipped with Toyota Safety Sense systems like automatic braking and adaptive cruise control, offering higher safety. The Previa lacks these technologies, making it less reassuring to drive. Price-wise, a new Sienna starts at over 300,000 RMB, while a used Previa is cheaper but has hard-to-find parts, making it less cost-effective in the long run. Overall, the Sienna suits modern families, while the Previa is more for nostalgia and collectors.

Technically, the Sienna and Previa differ significantly. The Previa features a rear-engine, front-wheel-drive design with the engine mounted under the floor, which was innovative at the time but compromised comfort, space efficiency, and led to heat dissipation issues, resulting in noise and front-row heat sensation. The Sienna, on the other hand, utilizes a front-wheel-drive platform shared with the Camry, offering flexibility with a 2.5L hybrid engine delivering 220 horsepower and fuel consumption as low as 6.5L. It boasts advanced electronic systems including lane-keeping assist, ensuring smooth handling, modernity, and reliability. The older Previa models, like the 2.4L inline-4 engine, are reliable but outdated in terms of power, with scarce replacement parts. In terms of drivetrain, the Sienna offers optional all-wheel drive for various road conditions, while the Previa's rear-wheel drive provides an advantage in snow but is less convenient daily. I believe technological advancements have made the Sienna superior in all aspects.

When on a tight budget, a used Previa can be found for tens of thousands, offering a cheap initial price but high usage costs with fuel consumption over 10L, expensive insurance, and troublesome repairs with parts shortages. The Sienna starts at 300,000 for a new model, with its hybrid version saving fuel in the long run and maintaining a moderate resale value—reasonable to invest in as it can still sell for over half its price after five years. The Previa, discontinued for years, has many issues in the used market like prone-to-fail air conditioning, requiring caution unless you're knowledgeable about its condition. The new Sienna offers stronger reliability, fewer faults, and easier maintenance, making it more cost-effective in the long run.

Having driven for many years, the Previa was a popular rear-wheel-drive model in the 90s, with a stable four-wheel-drive version that performed well in snow. However, the engine placement led to significant noise, a hot driver's seat in summer, and cramped space, especially in the third row. The Sienna, which replaced it, showed significant improvements: front-wheel drive for quieter operation, more spacious interiors, better seating arrangements, easier installation of child seats, abundant safety features, and comfort for long-distance driving. Maintenance is simpler, with everything easily handled at dealerships. The Previa's air conditioning often had expensive repair issues and is now rarely seen on the roads, while the Sienna is everywhere—a more reliable choice. Don’t hesitate when choosing a new car.

Daily commuting with the Sienna is smooth, thanks to its hybrid engine that provides quick starts in the city, low fuel consumption, and excellent seat support. The automatic air conditioning is easy to adjust, and the car's navigation system is practical. I test-drove the Previa, but the engine vibration was strong, the noise was disturbing, the interior felt cheap with hard plastics, and it lacked technological features. The space design is outdated, and the rear seats are cramped, making long drives tiring. In contrast, the Sienna offers spacious interiors, with the third row suitable for emergencies, stable high-speed performance, and a safety system with collision prevention. For urban living, the Sienna is the better choice, while the Previa is only suitable for occasional nostalgia trips.
