I have always wanted to drive an electric vehicle. I had always imagined it would be an eerie experience driving along in almost near silence with a good smooth shove from the torquey electric motor. Well, I still haven’t driven a full electric-only car but last week I came close, in the form of a Mercedes C350e Sport plug-in hybrid saloon. I have driven a couple of Mercedes hybrids before but both were diesel hybrids and neither were plug-ins. They didn’t give much clue as to what it is like to go electric as they only allowed limited use of the battery. Accelerate gently (and quietly) to 20mph and that’s your lot – the diesel then cuts in.
Driving a new Toyota Auris hybrid estate to Merseyside in January, I had a slightly better impression. As well as the initial acceleration, I managed to cruise briefly along an urban road at 40mph. However, the slightest tickle of the accelerator and in came the petrol engine. I did manage a reasonable 58mpg on the long, steady motorway journey though. Close but not quite as good as a typical family-sized diesel.
There is a big difference between the Mercedes and Toyota hybrids though. The Mercedes all had plenty of performance whereas the Toyota was about as lively as a snail with a hangover. I have not driven many cars (or even vans) which feel so sluggish accelerating from, say, 50 mph to 70mph on the motorway. That said, it is of course unfair to compare the Toyota to the much more expensive Mercedes. But petrol-electric hybrids may be the medium-term future if the authorities decide to take punitive financial measures against diesels and not everyone will be able to afford the likes of a Mercedes. Until Marty McFly and Doc Brown develop the flux capacitor and small-scale nuclear reactor to the point where electric-only cars are truly practical (feeding on banana skins and other household waste), it may be Back to the Past for current diesel owners who are used to the economy and performance of a modern diesel engine. For a lot of private buyers, a compromise on performance may become the order of the day if the only realistic option becomes one of the humbler petrol hybrid offerings, such as the Toyota. Incredible to think that diesel cars were thought of as noisy and slow a couple of decades ago.
Back to the Mercedes C350e. A seven speed automatic gearbox, two litre turbo-charged petrol engine with 211hp and an electric motor with 82hp which all adds up to, er, 279hp according to Mercedes’s own figures! The interiors of current Mercedes are really classy and this C-class was no exception – lots of brushed aluminium and high gloss black on the dashboard and leather seats.
I had to take this C-class demonstrator from Leicester to Derby and pick it up again two days later. The car’s sat nav took me on A-roads: skirting Ashby-de-la-Zouch, then north up through the pretty village of Ticknall and across the amazing and ancient Swarkestone Bridge. Much more interesting than the M1 motorway and the Mercedes was a pleasure to drive over this varied route. The battery pack (larger than in the non-plug-in C-class diesel hybrid) adds a lot of weight but the C350e still goes round corners without drama and with plenty of grip. It is quiet even when the petrol engine cuts in, which it does with a very slight nudge. Not imperceptible but almost.
The electric motor frequently did all the work on its own. It was very strange watching the needle on the rev counter drop like a stone to zero as the petrol engine closed down when I was cruising along. Then I was left with that eerie experience mentioned at the beginning of this post – near silence except for a bit of road noise. I don’t know why but this was really satisfying and I was able to cruise at 50 – 60 mph on battery alone for some decent stretches. So with the electric motor seeming to do its fair share of the work, I couldn’t have used much fuel, could I? Actually, the car managed, erm, 36.6mpg. Compared to its official combined figure of 134.5mpg. And I was driving very steadily!
Two days later and I was determined to do better when I picked the car up to return it to Leicester. The gentleman who had been trying out the car said he liked it very much but commented on how the fuel gauge had dropped alarmingly. As a result, it was very low on fuel and had only a 12% battery charge. I was beginning to wish I had slipped a couple of AAs in my bag just in case. The trip computer gave a range of 46 miles and I had 30 to go. Now there’s a challenge. Could I get back comfortably and even increase that margin of 16 miles?
Shortly after leaving Derby, I tried going to full electric-only mode but the car wouldn’t let me, presumably because the battery charge was too low. However, all was going well until I was about 10 miles from my destination. Apparently I still had a range of 32 miles – great, I should now be able to get there with a range of 22 miles to spare. Then the range figure suddenly disappeared to be replaced by a red petrol pump! The fuel gauge itself now had one small illuminated segment flashing on and off. Interesting. Had the car now decided that the computed range was not to be relied upon? I still had one ace up my sleeve though: electric-only mode. By now the battery charge was up to 17%. I was able to switch to full e power and cruise along for a couple of miles, even getting close to 70mph on a stretch of dual carriageway. This was a very novel and enjoyable sensation – a glimpse of the future perhaps. As I reached the outskirts of Leicester, the car announced that e-only mode was no longer available and the battery charge was down to 10%. I then spent the last few miles trying to eek out the most from the electric motor as I progressed through the suburbs and then the city itself. Negotiating roundabouts and traffic lights, I would accelerate gently (the car using the petrol engine if necessary), then ease off to allow the electric motor to take over on its own. I was able to keep the available battery charge reasonably constant because slowing down for roundabouts or traffic lights usually added 1% to the charge. Eventually – phew – I made it and recorded a passable 48mpg. I suppose that was not bad for a car capable of 0-60mph in 5.9 seconds and a limited top speed of 155mph. However, it took a certain amount of concentration to achieve that figure and all at a very modest pace (the 30 miles took me almost an hour and that was not because of any significant traffic).
So, what do we learn from all that? In short, cars like the Toyota are making a valiant attempt to match the economy of diesels but the Mercedes C350e is not really about saving fuel (or the planet) at all. OK, if you plugged it in every night and had a shortish commute, you may be able to get a decent return for each gallon of unleaded (the official electric-only range on a full charge is 19 miles). No, what this car is all about is going fast and saving tax. Lots of it. In the UK, the vast majority of C350e customers will be company car drivers. In the forthcoming tax year, choosing a C350e over a cheaper diesel C-class (say, a C250d Sport auto) will save a 40% taxpayer over £2000 in income tax due to the C350e’s very low, official CO2 emissions (48g/km). Not bad. Way more than enough to pay for the extra fuel – that’s if the company car driver actually has to pay for his or her own fuel. A lot of company car drivers entitled to a £40,000 company car are probably high enough up the corporate ladder to get fuel for private use paid for by their employer. Due to those officially low CO2 emissions (which are as realistic as the official 134.5mpg), the C350e scores massively here as well when it comes to income tax on free fuel. And here’s the irony – will a company car driver entitled to free fuel have any incentive to plug into his or her own domestic electricity supply?!
This week I drove:-
Monday: Mercedes C350e saloon (plug-in hybrid), Leicester to Derby
Wednesday: Mercedes C350e saloon (plug-in hybrid), Derby to Leicester
Friday: Volkswagen Caddy, Kettering to Bury St. Edmunds
The Mercedes plug-in hybrid was interesting – might be a full post in due course.
Meanwhile, we had a day out in the Cotswolds last weekend, an area of south central England famous for its quintessential Englishness. Rolling green countryside and picturesque towns and villages whose buildings have been chiselled out of solidified honey. We stopped in a couple of the more well-known places, Moreton-in-Marsh and Bourton-on-the-Water, the charms of which are well-documented. However, I will mention the rather brilliant Cotswolds Motor Museum and Toy Collection in Bourton, a wonderfully ramshackle place where you are guided through the history of motoring from its earliest days to the 1960s and 70s.
The cars on show include Austins, Morris’s, MGs, Jaguars, Rileys and a 1938 BMW 327. The information accompanying the BMW explained that the first BMW cars were Austin 7s manufactured under licence. Every day an education! The car that caught my eye, simply because of its name, was a 1911 Alldays and Onions. These were probably manufactured under licence from the German company, Jedentag und Zwiebeln GmbH. Or was it the French company, Chaquejour et Oignons SA? Not quite sure.
In addition to cars, there are motorcycles and old caravans and an astonishing array of memorabilia and old enamel signs covering virtually every inch of the walls. The memorabilia and signage are not just limited to cars. There are artefacts and advertisements for all sorts of things, plus of course the substantial collection of old toys. This is not just a journey through motoring history but a truly atmospheric and nostalgic look back at life in bygone eras.
Away from the bigger villages/towns, we also came across a couple of interesting places off the beaten track that are probably missed by most people:-
Longborough. This was really the main purpose of the trip – to look around the church in this quiet, pretty little village. My wife and daughter are heavily into genealogy and had traced some ancestors back to Longborough in the 18th century. These ancestors went by the family name of Tombs. So there we were looking around a graveyard for Tombs. I kid you not. Apparently, there was a Scottish branch of this family – the MacTombs – who were well-known race horse owners in their day. Unfortunately, the search was in vain because the older gravestones had eroded very badly. However, the village was charming and came complete with an inviting looking pub – the Coach and Horses Inn – but we had no time to sample it.
Donnington Brewery. En route from Longborough to Bourton-on-the-Water we drove down some interesting, narrow country lanes. Descending a small hill, we glimpsed what we thought was a large old house below us. It was nestling snugly between the hill and a lake. As we drove past, we saw a sign “Private Road Brewery Only” and then “Donnington Ales” on the side of the building itself. Wow! Is this the UK’s most scenic brewery? We didn’t stop but I have since looked it up. It is based in a 13th century watermill and the mill wheel is still used to drive machinery. The same family has brewed beer there since 1865. Unfortunately, there are no tours of the brewery but, according to their website, you can stop there and buy the beer! There is also a 62 mile circular walk (the Donnington Way) which goes past the brewery itself and 15 of the brewery’s tied pubs. Might be a bit wobbly by the end. The abovementioned Coach and Horses Inn in Longborough is a Donnington Brewery pub.
