leuning 写了： 2024年 1月 19日 19:49 功率=扭矩x转速。

2.5 的功率一般用用够。
和3.5比，问题是
1)要拖货的话，容易坏
2)要长期用，或当出租车，容易坏

因为必须更大的温度，压缩比。更复杂的机械。

That doesn't, however, mean that this minivan is boring. Resting under the hood is a powerful, 3.0-liter V6 engine that was stolen from the Camry parts bin. The engine isn't the only piece of equipment pilfered from the Camry; the Sienna rides on a stretched and modified Camry platform and uses much of the Camry's interior switchgear. Appropriately referred to internally at Toyota as "The Camry of minivans," we can only assume that the company expects this creation to be as popular as their hot-selling sedan.

In order to harness the 194 horses at work under the hood, engineers put antilock brakes at all four wheels of every Sienna. Other safety equipment includes dual airbags, side-impact protection that meets future federal standards and seatbelt pretensioners for both front seats. Last year the Insurance Institute for Highway Safety conducted an offset crash test of the Sienna and called it "the best performing vehicle in the history of the test."

Powering the minivan is a 3.5-liter V6 that produces 296 horsepower and 263 lb-ft of torque and is paired with an 8-speed electronically controlled automatic transmission.
