The 2014 (60Ah) i3 REx vs The 2017 (94Ah) i3 REx

Image
255 miles of combined range? This range estimator is probable a little more optimistic than real life, but I definitely believe 200 miles is possible with the new 2017 i3 REx.  What a difference three years makes.  I was able to secure one of the first 2017 BMW i3 REx cars that made its way into US dealer inventory, compliments of Chris Chang, Sales Manager at BMW of Bloomfield here in New Jersey. The vehicle is mostly the same as my 2014 i3 REx, the one big exception is it has the new 94 Ah battery cells, which increase the overall battery capacity from 21.6 kWh to 33 kWh without increasing its physical size. That was necessary, since this isn't a redesigned i3, so the battery modules had to fit in the existing battery tray. The 2017 i3 REx in Fluid Black next to my "Moloughney Red" wrapped 2014 i3 REx As much as I wanted to check out the moonroof option that this car had (finally the moonroof is available in the US!), there is no denying the single most important improv...

Exclusive Interview with Chevy Bolt EV Chief Engineer

Image
The 2017 Chevrolet Bolt EV will be available for sale in less than a year. A five seat hatchback with a 200+ mile electric range with a base MSRP of about $37,000. Will the Bolt affect i3 sales? This week at the North American International Auto Show I had the opportunity to sit down with Chevrolet  Bolt EV Chief Engineer Josh Tavel. We covered a variety of topics related to the Bolt EV, which was the cornerstone of the Chevrolet press conference at NAIAS this year. I originally posted this on InsideEVs, but I believe the readers here would also be interested in reading about a potential i3 competitor which is coming to market in less than a year.  I started out asking Tavel what he felt were some of the biggest challenges his team faced with the Bolt. Here’s Tavel’s response: “This is a very different car.”  “You might expect me to answer this by saying one of the major components like the battery or electric motor, but that really wasn’t the case. We’ve been doing batt...

BMW i3 Overactive-Active Cruise Control

Image
When activated, the ACC displays an icon of a car on the road ahead of you. That means you are locked onto a vehicle in your path. One of the coolest features on the i3 is the Active Cruise Control. The Parking Assistant is cool tech also, but honestly I can't see myself ever using it except to show it off to friends. I can park the car just fine on my own, and faster than the Parking Assistant can. The ACC on the other hand is not only really cool, but very useful. Whether I'm stuck in slow moving traffic or driving long distance on the highway I'm finding myself using the ACC more and more. It's kind of like locking onto the car in front of you with a tractor beam from some sci-fi show and letting it pull you along. However there is one thing that needs to be improved upon with the i3's ACC. It will occasionally disengage by itself without warning. Yes, it does post a notice on the center display screen that it has deactivated, but unfortunately that is already af...

Born Electric Guest Blogger: Meet Scott From California

Image
Hi, my name is Scott Lawson and I was Born Electric on August 11, 2014. I confess: I am not a ‘car guy’. For me, cars are dirty explosion factories full of toxic liquids and endless grime. Oil changes, frequent fill ups, dusty air filters, and a noisy engine seemed to be an unnecessary evil. If I was to get an EV, I wanted it to be 100% electric, no engine, no gas, no oil, no going back! At times, I have even thought that if I lived in the city I would outsource my transportation to taxis, buses, and trains. But living in the so-called mega-city of SoCal (from San Diego to Santa Barbara) with inadequate public transportation options, a car is required . And since I am confessing, I should say I love traveling fast and zipping around in a driver’s car. Over the years BMWs have fit my needs well but were still powered by gas. I considered the LEAF for a fleeting moment and the Tesla Model S seemed like a car for executives or super models! And costs twice as much as any car I have ever o...

Mountain Climbing With an i3 REx

Image
Loveland Pass, Continental Divide, Colorado. Elevation 11,990 ft A few weeks ago Don Parsons of Denver, Colorado took his i3 REx on a 128 mile road trip from his house to Loveland Pass (Continental Divide, Colorado). On his way up to the 11,990 ft elevation of Loveland Pass he stopped at Beau Jo's Pizza for lunch and to charge on their public ChargePoint EVSE where his i3 REx accepted 8.9kWh's of juice to help with the rest of the climb up the mountain.  The car showed 18 miles remaining at the top of Loveland Pass, and he nearly made the trip entirely on electricity when 62 miles later the range extender kicked on and he was only 2 miles from his home.  The trip summary:   -64 miles each way -8,960 feet of climbing, 2329 Feet of descending on way out -2329 feet of climbing, 8,960 feet of descending on way back Having heard about this Continental Divide conquest, I asked Don if he wanted to write a guest blog post about the trip, but he offered to do one better. His next ...
