HYPERMILING & CHARGING IN AUDI ERON GT
Hypermiling. Driving a car as efficiently and comfortably as possible. Enso tyres recently equipped a Renault Zoe using their new EV-specific tyres. They found that they were more efficient than standard rubber and can drive a Zoe 475 miles on a single 52kWh battery charge.
This was similar to what I had been doing in my Audi. It was more economical than I had expected. It was expected to be roughly the same in efficiency as other EVs with similar size, weight, and power and to return approximately 2 mpkWh. It didn’t. It was consistently doing 2.5.
This is probably due to the warmer weather. For example, the Zoe’s efficiency was 9.1mpkWh. However, it achieved 10.6 in tests on hotter days. Progress is progress and I was inspired to drive more slowly to see where it went.
This month, I was, well, not hypermiling as that would have been dangerous, the Zoe’s average speed about Thruxton was 18.2mph during the record attempt, but just being a normal law-abiding citizen. It’s been quite a journey, with almost 1200 miles covered, which includes a 600-mile round trip from Durham to Lancaster. Overall, I was able to get 2.9mpkWh with a maximum of 3.3 in a 50mph section of roadwork on the M6.
This is enough to give Audi a true 250-mile range. This was something I discovered later, when I drove to Scotland in a Range Rover diesel engine and got 500 miles. That’s the truth. Audi is a great long-haul car. It rides smoothly and comfortably, glides along effortlessly, and wants to go on. But it can’t.
I have an iron bladder. I was just getting my stride but after 200 miles in the GT, I had to stop in Leeds for a recharge. Skelton’s new services are wonderful and well worth the diversion. You shouldn’t use them if you plan to use the Ionity charging cables. A man was already there in his Merc EQC. He was confused. I joined him, and we fought the system for ten minutes. His teenage son was the one who broke the deadlock. He discovered that these Ionity chargers work only if the app is downloaded.
Then, rob your wallet. PS45 cost 65kWh. The previous evening, 87kWh cost me PS45. It was less than half the price. At current pump prices, an Ionity stop would be equivalent to doing 27mpg vs 117mpg for home fill.
Are you an owner of an electric vehicle? As far as charging is concerned, it’s the wild west. Half of the stations don’t work correctly and the prices vary greatly. If there is a five-pence per litre difference between petrol stations, we get excited. This could add a PS2.50 to your bill. The difference between electric suppliers is not four percent, but rather 400.
Or infinity. My Lancaster hotel offered free charging that night. It was free! I woke up to a fully charged battery. God I felt smug.
Even though I had free fuel, it wasn’t enough to convince me to drive. Electricity is what brings out my inner hairshirt. I turn off the air conditioner, and then switch to Eco mode. This brings with it additional power, acceleration, comfort, and a lot of enjoyment. This is why? This is not me. It could be the Audi. I don’t think a Taycan made me feel this way.
This car is more relaxing, it moves with the road and feels smooth. Every input produces the perfect response. Although there is a little more wind noise than I would like (I’m certain double-glazed glass is an option), it glides along just as smoothly as an S-Class, Bentley Conti GT.
Next month, I will go back to my old ways and continue barreling about. And I will make a prediction: the economy won’t fall that much. Remember that the petrol economy is mainly about heavy fuelling under acceleration and energy wastage while braking. Electric driving, I believe, will eliminate the peaks as well as the troughs because it has recuperation in your favor. After the Enso team had completed their feat, we charged the Zoe, and then I did a flat lap of Thruxton. 1.2 mpkWh. Assume my prediction is wrong.
