Where did you hear 200 miles at freeway speed? I've only heard an estimated "more than 200 miles" on the EPA test cycle which includes a mix of city and highway driving conditions.If I can buy one for $30K and it will actually go 200 miles at freeway speed, I wouldn't care if it had no cruise control at all!

All true, plus I live in the NW and when it's cold(ish) it also tends to be dark and wet. Heat, defrost, lights all reduce range, and wet roads and rain also create more rolling resistance/drag.GetOffYourGas said:Oh, and I should mention that temperature plays a huge role at those speeds. Cold air is denser, and creates noticeably more drag. So my numbers above are at a typical 50F ambient temperature. No knowing your location, I shouldn't assume that you have the same climate as I do. In a warmer climate like southern California, you will do much better on the highway. But even there I wouldn't expect 200 miles at typical highway speeds.

cmfrazier said:Hi everyone, I just registered the post about this topic. I'm currently Leaf owner, and I am expecting to upgrade to the Bolt later this year. After doing some research today, I've come across the topic of no adaptive cruise control on the Bolt! I cannot believe GM would release the Bolt without this feature. It has all the necessary sensors already built into the car. Anyone else disappointed by this?

It seems to me that it's just a software update. In my Premier, the car tells me how far behind I'm following the car in front of me. It seems that GM can update the software to apply the brakes to slow down the car in cruise control. It has the capability to brake to stop when it's at low speeds, you'd think you could do this w/o additional hardware.
It's very weird to me.
While I'd love to see ACC in a 2018 model and would likely delay my purchase for it, I really doubt that they're likely to change the braking system until the next major model refresh - and that won't come next year.Posatronic said:...it will not have adaptive cruise control. Straight for lead engineer, the bolt would need blended brakes. They did not go with blended brakes. Maybe '18 or '19 model.
Whatever the meaning of "blended brakes" is, the Bolt doesn't have the same kind of braking system as the Volt does, and Josh Tavel has stated that the Bolt's system doesn't work with ACC.EldRick said:Meanwhile, back in reality, the Bolt appears to have blended brakes:

I'm glad to hear that it is improved, as the system on my SparkEV always has a slight tactile "bump" at the transition, when you brake hard enough to get the friction brakes involved, and suddenly you hear the brakes working.Jeff Cobb has more detail about the braking system on the main page. Basically the Bolt EV and the Volt 2.0 does, as WOT, said, use the same system:
The answer, according to Ligouri, is that the Bolt EV uses a new and better-feeling brake pedal system that continues to include both enhanced regenerative and friction braking.
According to one usually reliable source, the Bolt EV and the second-generation 2016/170 Volt both use a new brake pedal actuator known as the iBooster from the automotive parts supplier Bosch. This new system provides better brake pedal feel while still allowing the car’s electric motors to capture up to 60 kilowatts of regenerative power into the battery during moderate braking.
Initial pressure on the pedal slows the car by enhancing regeneration levels while stronger pressure on the brake pedal seamlessly transitions to hydraulic friction braking.
This seems clear. There is still blended braking, just a different/superior implementation than on the Volt 1.0. May the "blended brake" issue RIP. One funny thing is that the reviewer from cars.com said the braking system on the Bolt EV was vastly superior to the one on the Volt and it turns out they are the same or similar. Then again maybe he was referring to the Volt 1.0.
