I started compiling this report to you in June, my Clio, together with it's Tunit, being 12 months old with 20,000 on the clock, but the sun kept shining so working outside took precedence over the computer. Here are some facts and figures on the cars perfomance. Most of my driving is on country lanes and B roads with some town miles, this type of driving gives regular averages of 36 mph and 67 mpg. I have made a number of trips to Southern England, doing most of my driving early morning to avoid delays. A typical round trip of 650 miles (90% motorway) giving averages of 69 mph and 61 mpg Lest you think I pussyfoot around, I had to replace a 4 Continental tyres at 12,500 miles, I guess the road surfaces on North Lancs roads are abrasive... Renault expect the Clio to return 67 mpg overall, but as I recall the long term test results in Diesel Car show consuption of their Clio to be mid 50's. Are the DC drivers thrashing their Clio, day in day out, or are the Renault figures overly optimistic? Either way I am more than happy with my Clio with the Tunit fitted. You may recall that my Clio was the first 80 bhp you had worked on and the Tunit was tuned to give maximum performance through the gears, rolling road tested at 103bhp. Once again thank you for your superb after sales customer service.
