Car and Driver 有一個欄目叫
Long Term Test, 他們會開一年多到4,5萬麥,然後給出評價報告,如果感興趣5萬麥以下可靠性,可以看看。





下麵是Ram 2013的

Like a good employee, our long-term Ram stayed healthy during its 40,000 miles, only calling for service (oil and filter change, inspection, and tire rotation) when its computer alerted us. That happened just four times for a total outlay of $232; our most expensive service stop set us back $92 and also included a new air filter. We spent another $84 replacing a taillight that was damaged while maneuvering into a car wash, and $134 for a new tire after a nail puncture. Replacing an odd $3 fuse that was on long-term back order from the dealer was one of our few headaches.

In what was one of our briefest long-term tests ever (349 days for an average 115 miles per day), the 2013 Ram 1500 proved one of the most versatile and trouble-free vehicles we’ve ever subjected to a 40,000-mile evaluation. Although our model’s entry price and fuel bills were significant, even with the V-6, this truck rarely delivered less than what we asked of it, be it on a quiet ride across town or a long-distance trek with a prized, if rusty, possession. As one driver summed up in the logbook, “It’s the ultimate four-wheeled multi-tool.”

可靠性是一個統計學定義,試驗的樣本的多少決定其結論的的意義 -W050404- 給 W050404 發送悄悄話 (0 bytes) () 11/07/2014 postreply 06:16:23

我和工廠打交道快20年了,全檢最好,有些項目可以做,但是很多是抽檢,抽檢率是根據產線成品率出來的,不過抽檢千分之一 -soccer88- 給 soccer88 發送悄悄話 soccer88 的博客首頁 (30 bytes) () 11/07/2014 postreply 09:16:47

開冷車和開熱車的區別究竟在那裏呢?為什麽冷車啟動時費引擎? -hua126- 給 hua126 發送悄悄話 (0 bytes) () 11/07/2014 postreply 20:24:11
