Well its time to do the comparison. Having had my BMW i3 60ah (19kwh) Rex for 13 months and 41k miles, I decided it was time for something with better range. 3 Days a week I do M1 Jnc28 to Central London and back (142 Miles each way). The i3 is great but it takes a charge stop each way (Milton Keynes) which is 89 Miles from Home, and I have to drive at 58mph to get there on the battery in the summer and in winter I still end up using the Rex engine for a few miles. So decided a larger battery EV would allow me to do the journey nonstop saving a 30min charge stop each way and also be able to drive nearer the speed limit. At first I was going to upgrade the i3 to the newer 90ah (30kwh) Rex, but the cost to change was insane, getting a car just a month or 2 newer but with the bigger battery was going to cost me 10k. So I started looking at the Renault Zoe ZE40. I was initially put off by the fact the battery is on lease so as well as buying the car you need to lease the battery at £110 a month, that was not going to work for me.. But I found out Renault also sell a battery owned version for £5k more. So to crunch the numbers. The Zoe I decided on was the top spec Signature Nav, Along with the Q (Rapid Charge System) £750 extra, and Metallic Paint £600 extra. So the total OTR was £31800, take off the £4500 OLEV Grant and a very good Dealer Discount Of Over £7700 (Carwow). Brought the entire OTE down to £19400 As I will be doing 150k miles over 4 years my idea is to fully depreciate the car over that period (£5k per year), and at the end of 4 years scrap the car and reuse the battery with whatever capacity is left as a home energy storage system.. With my work allowances for travel parking and CC I will be well in profit on the car after year 2, so if it does not make it to year 4 no issue. Anyway enough waffle down to the cars. The i3 is a very marmite car. Personally I love it design drive, all of it its the dogs danglies to me. (I know to a lot of others its Mhhhh) I find the interior is a calming place to be but its fun to drive and fits my needs perfectly. So why buy a Zoe (At this point I admit I bought it without driving it or even ever sitting in one), it was the range that sold it. In My i3 on a good day I can get from Home to Alton Towers and back again (85 Miles) and just get home before the battery dies, (Eco Mode with All Heating Off) In the Zoe today, I went from Home To Alton Towers, Alton Towers to Derby, Derby to Sheffield, Sheffield to Home ( 172 Miles) and came home with 30 miles range remaining Thats it the entire reason.. Miles in the tank. So how does the Zoe Compare Design BMW i3 WINS Zoe its bland and very "car like" if you dont like driving its the perfect car for you. Interior, So much cheap hard plastic, Shiny slippy leather seats. No Storage, Technology ZOE WINS Entertainment/Computer, Zoe much better than the i3, having a TomTom based system rather than the BMW idrive its easy to use and seems to keep a better route option if there are jams, the i3 goes bonkers. Being touch screen its much better to use. Heating/Cooling. ZOE Wins nice easy to set AC/Climate and a low energy heat pump as standard across the range (£750 extra on i3) Ride. i3 WINS. The Zoe is sluggish feels like a normal car, the i3 is eager nippy and holds the road well Rattles and Interior Noise. ZOE WINS (Bit of a surprise), in the i3 there is always a rattle from somewhere, in an EV very irritating in the quiet environment, in the Zoe its been perfect. Very surprised considering the cheap interior. Range. ZOE WINS (Obvious more than double the battery and range). Charging. BMW WINS. Difficult this as the Zoe has no DC Rapid Charge at all, it only charges on AC, the standard Model can charge on upto 32amp 3 phase (22Kw/Hour) And the Quick Model can charge on 64amp 3 phase (43kw/Hour), which is as quick as rapid DC, but it seems a faff and the Zoe is a very picky about what chargers it likes the i3 on DC is just plug and go. COSTS TO CHARGE - It all depends on what Supplier you use, but I charge on Eco7 overnight, the 19kw i3 uses about 21kw from empty to full including charging losses in the system, as i pay 5p kwh it costs about £1.05 to charge for 85 miles range. The 41kw Zoe uses about 46kwh including charging losses so costs £2.30 to full charge but gives over double the range of the i3, so on both cost per mile is around 1.2p On a straight costs basis the Zoe is a clear winner being the biggest battery EV on the UK Roads (Except Teslas) and coming in under £20k battery owned for a top of the range £16k for a mid range. Makes it a great starter EV.. I will be happy driving my Zoe to London and back for the next couple or years, but wish BMW had come out with a 40kwh i3 last year SO ZOE WINS ON Price Range Seats 5 Tech i3 WINS ON Looks Speed Comfort Quality Ease of Charging Luckily I am keeping my i3 as my weekend fun car, and the Zoe as the Weekday Motorway Mule, so I can have the best of both worlds. What says it all is I will put up with a car that does not push all my buttons to save time stopping to charge, I purchased the car from a dealer in Salisbury Wilts (185 Miles from home). (Was the best Price by Far). Vicky drove the i3 back home and I drove the Zoe, Both were fully charged in Salisbury, She had to stop at Abingdon, Warwick for rapid charges, and a topup at Leicester Forest East Adding 2 hours to the journey, the Zoe made it home on a single charge. Life is too short for that many charge stops.
