I’ll be covering Bristol and Exeter from now on in my job. Yesterday, I encountered some steep climbs… it was like my Mercedes C200d just lost all steam. The speed dropped from 70mph to 59mph on a steep gradient. My ears were immediately blocked from the pressure.

Any recommendations for a decent hill climber?
More torque at lower RPM? High RPM and low torque?
What would be up to the job?

I don’t carry a lot of equipment. Some plumbing tools and replacement parts from time to time.

Cheers

Mr E

Dropped a few cogs but it took forever.

Something with superior power to weight then.

As above, select the correct gear and open the throttle. It’s been a while since I’ve driven a car which can’t maintain 70mph on the motorway and I’d be highly surprised if a C200d can’t.

ETA: maybe a car which will do this for you. An automatic with cruise control will open the throttle and kick down if it is slowed by a hill.

My F30 335d really comes into its own on hills. You want torque for the hills.

In my experience, the best cars at hill starts on steep hills are cars with a torque converter auto, large naturally aspirated petrol engine and four or rear wheel drive.

Probably easier to change gear than change your car.

You might be talking about Haldon Hill on the A38. Back in the day there'd often be a bunch of cars stranded there during the holiday season due to overheating.

You can easily sustain 70 in a supermini by changing down a gear beforehand and holding the revs high until the top.
But even a relatively powerful car struggles if you simply boot it in the wrong gear halfway up the hill.
As others have mentioned, sort out your gear discipline instead of your car. You don't need to be a 'powerfully' built director in a BMW to make it to the top.

Or just chill out and allow the speed to drop a bit, while also saving a ton of fuel.

A friend of mine used to have a very steep driveway. I could only get up there in my metro using reverse, I guess due to slightly higher gearing and weight transfer. So, my recommendation would be to go full pelt backwards up the hill, J turn at the top and continue forwards.

All you need is a torquey diesel, anything from a 220Cdi upwards, so a good excuse to upgrade to a C350 Cdi.

A remap will do the trick.

OP, are you sure your car is working correctly? Its been years since I've had a car that struggles, and my daily hack is a mere 1.7CDTI Astra.
Years ago, I drove my folks Rover 75 diesel. This is a car already known for its steady nature. However, on this occasion, it was dire. I told my parents I thought it was faulty. I think they had just become accustomed to the slipping performance. Turns out it had a duff MAF sensor.
Performance was fully restored after that was replaced.

Yes, that’s correct. I’ll check the car for air tags. Thanks though. I did see a few cars struggle but not break down.

Worth checking. It’s due a service in April anyway. Tend to have two oil changes a year with the high mileage.

Always wanted to see these live. Thread jacking myself here but wonder if there is a place in the UK to watch or even drive one?!
