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

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 Bolt has no heat pump, unlike LEAF and Ioniq.OrientExpress said:LeftieBiker said: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?

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:

Obviously, generally applicable to any LRR to performance tire swap. There were also changes in noise.. . . 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). . . .
LKK said:I think the radio is on all of the time in some newer cars to support non-stop audio requirements like the infotainment, GPS, and active noise cancellation. That said, I can't understand why radio audio could not be muted if the driver turns the radio off. I know the Volt suffers from this flaw, you turn the radio off and it pops on whenever the infotainment or GPS makes an announcement. Guess the Bolt does this as well.
Well, no surprise. From http://media.gm.com/content/dam/Media/gmcom/investor/2017/dec/Deliveries-November-2017.pdf (linked to from http://www.gm.com/investors/sales/us-sales-production.html), US Bolt EV sales are a drop in the bucket vs. rest of vehicles, esp. their bread and butter vehicle types.jjeff said:As par for the course, none of the vehicles I'd really be interested in purchasing were on the large sales floor, which were all basically larger SUVs and pickups :roll:
