Re: Chevrolet Bolt - 60 kWh, 238 mi, < 7s 0-60

Bolt resistive heater, sucks in Winter; old news. But I have to think sucking at 150-170 miles of range might not be as bad as excelling with 100 miles of range 8-)

For once Dave and I agree. The Leaf's range is so much lower that it would have to have almost double the Bolt's efficiency to beat it in Winter driving.

The LEAF's heat pump HVAC system is much more efficient than the old resistive heater, but that is old news since 2013. What sort of HVAC system does the Bolt use?

The Bolt has no heat pump, unlike LEAF and Ioniq.

And the Ioniq reportedly accepts charges at up to~80 kW.

So the question discussed previously on this thread of "at what distance will an Ioniq pass a Bolt on a long trip?" appears to be only about 300 miles, under the cold weather test conditions below:

edatoakrun wrote:Autobild tested eight Euro-BEVs in a real-world winter range test, and the Bolt (Ampera) did quite poorly in terms of efficiency.

Suggests that A 2018 LEAF (not tested) as well as an Ioniq (as discussed previously) might well cover a long winter trip with recharges in less time than the Bolt, despite its much larger capacity pack.

...The German auto magazine Auto Bild decided to test the range of eight electric cars. With an outside temperature of just 5º C and the AC set to 21º C, all electric cars were submitted to the same 143 km route, which included a 43 km long highway ride at speeds up to 130 km/h...

A driver posted the following charging results for an Ampera using a ~100 kW charger, suggesting max rate is in fact, in the ~55 kW range:

The charger showed the following values:
7% SOC 52.6kW
11% SOC 53.7kW
21% SOC 53.8kW
33% SOC 54.6kW
44% SOC 55.2kW
49% SOC 55.5kW

How many miles before the 2018 LEAF passes the Bolt on a long trip under the same test conditions, if ever?

Bonus question:

How many miles before the Ioniq passes the LEAF, under the same test conditions, if ever?
no condition is permanent

Via IEVS ex MT:
How Ultra-Performance Tires Affect The Chevrolet Bolt
https://insideevs.com/ultra-performance-tires-chevrolet-bolt/

. . . The differences were brought into sharp focus by MotorTrend recently when they exchanged the stock low rolling resistance (LRR) rubber on their long-term Chevy Bolt loaner with definitively more sticky hoops: a set of BFGoodrich G-Force Sport Comp-2 ultra-high-performance (UHP) tires. Lucky for us, they took detailed notes of the results. . . .

    "Based on the EPA-rated 238-mile driving range, our driving range decreased by 10.2 percent.The average ideal range after charging dropped from 248 miles to 224 miles, and the average predicted range dropped from 206 miles to 186 miles."

After subjecting the Bolt to another, ahem, battery of tests involving their EQUA Real MPG team, MT determined the new efficiency rating of the Chevy while wearing UHP shoes to be 89.2 MPGe in combined driving, down from the stock 122.2 MPGe (note: this EQUA Real MPG stock result differs slightly from the official EPA number of 119 MPGe). . . .

Obviously, generally applicable to any LRR to performance tire swap. There were also changes in noise.

An acquaintance of mine recently acquired a Bolt, and my initial impressions were pretty good as a whole. The negatives that others have mentioned before where quite noticeable even during the short time I drove it, however, such as the horribly uncomfortable and hard seats, and the cheap hard plastic interior. Regarding the UI, I despised the animation of the car rotating every time I want to get to an option. It wastes time.

Very peppy, obviously faster than my 2012 Leaf, and of course the dramatically increased range is a good thing. Even so, holding out for the Model 3. The one I drove was a $42k trim, and it felt less comfortable and luxurious than my 2012 SL Leaf.
Pulled the trigger on going EV on 10/2016 with a 2012 Leaf, and a Tesla Model 3 reservation expected to receive in June 2018.

I've rented a bolt a few times. Was difficult to figure out how to turn off the radio, and every time restarted the car the radio would come back on. Drove short trips of less than 15 minutes. Didn't notice pain in my hip until after I started reading reviews of the Bolt. :P Overall I think it is a really nice car, but I value safety features like traffic aware cruise control which the Bolt doesn't have. Strongly prefer a larger car also, since I have 3 children in the house. Don't have an issue with hard plastics. Tried to lease one back in November, but dealers where low in inventory.

Currently planning on buying used Model S with rear facing child seats. Tesla told me they will have a ton of those available first few weeks of January due to strong lease sales 3 years ago.

You can make the radio optional by placing a thumb drive in the USB port.

Will GM never learn :roll:
They were the same company to make an HVAC system where you could not turn off the fan, if you have HVAC on the best you could do was turn the fan down to the lowest speed. I would NOT like a car where I could not turn OFF the damn radio! and I don't mean just turning down the volume, I want it OFF.
