the hybrid mode is not too bad (still slow). the slow EV acceleration is due
to a small electric motor (80 HP). the hybrid mode has a combined 134 HP.

One day, I was behind a volt on the ramp of freeway. He... I should say...
he flew away.
I was driving a E90 330, pushed the paddle all the way down to the engine!
But, he just like a rocket flew away from my view.
I hope the new Volt can be in 30k - 40k range. Looks like it's reliability
is ok. |

0-60要9秒多的车。

发帖数: 3419 | 7 电车拼加速和厂家对电机扭矩输出的调校有很大关系
Model S 的电机最初0-30扭矩输出是水平直线，冰壶贴过图，厂商故意给压平的
如果对电机输出不加约束静止起步全电门输出，危害有如下几个，我能想到的
1. 电机过热，电机低转速全电门电流极大
2. 损坏电池，这种瞬时超大电流输出很伤电池
3. 轮胎抓不住地，扭矩远超轮胎抓地力，无实效，纯粹自找麻烦
4. 对drive-train损伤，打断齿轮不夸张
5. 耗电，静止或者低速猛加电 电量消耗远超高速80MPH巡航
还有什么别的继续补充
所以一个电车加速慢短板在哪还得具体分析

Most likely in the Sports mode. I wowed from my heart when I did that for
the first time. Unfortunately I can not save the default drive mode. Not a
big trouble since I only use Sports occasionally.
the reliability is more than ok. actually, it is very impressive. the gen2
volt is better in every single way (except the nose, I like Gen1's nose
better). The price should be close to the Gen1 volt (34k base), except you
will not likely to get the big (~$5000) discount the dealers offer for the
Gen1. still, for a car with 50mile AER, it is worth it.

I know. using a modified firmware, the 0-60 for a Gen1 volt can be as low as
5.5 second, see this video

看价格了，比一代高肯定完不成销售任务
二代卡迪ELR应该没可能推出了

originally roumored to have 5 modes:

but in the Detroit show releases, gm denied the 5th mode:

发帖数: 2696 | 13 这几个因素都是对的
不过逻辑上反过来了
不是说电机本身有多少多少能力然后厂商去压制它
而是这种custom application的电机的设计本身就是按照一开始定的外特性指标来做的
余量肯定会留，但是不会超过初始需求很多，因为本来就没打算用到过载
至于说电机的低转速输出力矩是一条水平直线，现在的几乎所有感应电机配合变频器都
能做到。不是个什么特别的事情，工业上就是这么用的。多少年了。

电车有 instant torque，日常驾驶除了上ramp，需要的是瞬间反应，而不是持续加速
能力。这方面油车变速箱有降档的过程，即使降档很快，转速也不是突变到高转的，如
果变速箱降档不积极，就更糟糕，要慢慢等转速上去，而01加速体现不出来这些弱项。
一般测试时起步都吊转速，中间也不存在降档，像双离合这种一路升档牛逼，01测试成
绩好看，
但需要突然降档的时候就慢了
另外电车松油门以后动力下来的也更快。所以整体上更有人车合一的感觉
我对下代volt的期待一是可靠性，二是后排中间能坐人，而且trunk达到prius的水准。
能做到会买。开起来爽，还能solo carpool，电还省钱

it depends on the regen settings. in the 2014 volt, the default regen level
feels just like a normal car, but in the L-mode, the car slows down
significantly. the volt gen2 has a "regen on demand" quick switch on the
steering wheel, one can adjust regen strength conveniently.
the cargo space is pretty much the same as the gen1 volt, which is 10.6 cuft
(prius: 21.6cuft). admittedly, it is small, but IMHO, it is very functional
with the hatchback design and fordable seats. I even managed to carry a 9ft
Christmas tree in my volt last week. We do shopping regularly with my son's
stroller in the back, no issue at all.

发帖数: 320 | 19 哦，我指的动力下来快是指加速度而不是速度，因为油车松油门有升档的过程，也有转
速有掉下来的过程，尽管这过程很快，但还是能感觉到0.几秒的加速度的迟滞。电车就
没有
至于动能回收刹车，个人其实比较讨厌那种一送油门就减速的设定
