The crash test data isn't too bad, but I was worried from the start about the parking brake lever poised right in front of my left shin, and the offset crash results bear that out:

The Leaf is no Mercedes or Volvo!


The only IIHS test the Leaf scored poorly in was the Small Frontal Overlap test. And for that matter, so did quite a few high end cars at the time the IIHS first did such testing, including the Mercedes C-Class, so the Leaf isn't necessarily an outlier for that time period.

EuroNCAP gives the Leaf its highest rating of 5 stars: https://www.euroncap.com/en/results/nissan/leaf/10939

Yes, and a friend of mine got horribly injured in just such a crash (on a 30 mph street) a few years ago when some d-bag crossed the center line. Broken femur AND broken pelvis. They bought a big Volvo wagon after that. Those incidents are no joke and it's a fairly common type of crash. Nissan should try to do better.

I don't know about the Euro ratings, but I believe in the US ratings, cars are rated against other cars of similar size. A small car that gets a good rating is not as good as a big car that gets an equal rating.

But, in the last month as "winter" weather (Seattle winter, so you know, NOT really winter), my range has tanked due to using heat, defogging (not optional!) and lights and wind and rolling on wet road, which apparently all matters although you never notice it with an ICEV.


You need to avoid using both the heat and A/C at the same time - that's what's hurting your range, because the resistance heater is running as well. Let the heatpump work in whichever of the two modes is better at the time, and range will be better. You can also alternate them every 10-15 minutes or so.

PS - in the winter you are forced to use the heat and a/c to defrost and heat the interior.

Anyway, as a high school commuter car, I think the crash tests are not realistic. Those pictures were of a car that took a slice out of the area of the headlight. ANY CAR will take a bad hit there because there is only front bumper, a flimsy fender, and the wheel and suspension to absorb the hit. There is no structural strength at the left and right edges on any car.

What I am saying, is that I will have no problem having my children drive the Leaf.

No, there are big differences here. A really snub-nosed car like a Leaf is at a big disadvantage. Compare it to a Subaru Impreza, which gets a GOOD rating in a small overlap front crash. The Subbie is otherwise about the same size, but it has a huge amount of additional structure out there. There is some steel in that bodywork that is not insignificant. The Leaf gets a POOR rating. Not Acceptable. Not Marginal. Poor, because you have all the extra momentum of the battery under the seats, and nothing out there to crumple and absorb the work of slowing that down. It's really kind of a thing.

Cars with shorter noses can have impact absorbing plastic foam filling the nose area. That would be the logical fix for the Leaf.

Because of the weight of the battery under the center of the car and energy absorbing crush zone at the back of the car I hardly felt the impact when my 2011 was rear ended by a 3/4-ton four wheel drive Diesel pickup that failed to stop for the red light (I was already stopped and waiting). I was even able to drive the car out of the intersection to a safe place to park. Most cars of all sizes performed poorly when the IIHS first came up with the minimal overlap offset frontal crash so I am not concerned about that issue.

Looking at your signature line, apparently the Leaf's safety record is not enough of a concern to dissuade you from purchasing one long after its IIHS Small Overlap results were published.
