There is a Greek Magazine called "4 wheels" (4 Trochoi for those who've done greek at school!) which does acceleration and deceleration tests on every car they test! In January 2006 they tested the GP 1.4 8v and the 1.9JTD Sporting, their findings are the following:
GP 1.4 8v (77bhp @ 6,000 rpm)-------- 1.9JTD (130bhp @ 4,000rpm)
0-37mph 5.3" ----------- 4"
0-62mph 13.8" -----------9.6"
0-74mph 21.4" ------------14"
quarter mile 18.9" @ 71mph --------------17" @ 82mph
19-31 mph (3rd gear) 4.5" -----------------3.6"
31-50 mph (3rd gear) 6.4" ------------------3.5"
50-68mph (3rd gear) 8.6" -------------------5.1"
25-37mph (4th gear) 6.2" --------------------5"
50-68mph (4th gear) 10.2" ------------------5.5"
74-87mph (4th gear) 11.8" -----------------5.3"
31-44mph (5th, 5/6thgear) 8.2" ----------------7.1"
50-68mph (5th, 5/6thgear) 13.7"------------- 6.8"/9.2"
74-87mph (5th, 5/6thgear) 15.6" --------------5.9"/7.2"
Breaking 74mph-0mph metres/g 62.7m/0.89g------ 58.5m/0.96g
Weight (manufacturer/actual test car) 1,040/1,116kg ----1,205/1,294kg
Weight distribution front%/rear% 60.9%/39.1% ------66.1%/33.9%
Small wonder some of us find the Sporting front heavy compared with its petrol siblings, whereas the fact that some of us are achieving 50mpg+ from a car that weighs nearly 1,300 kg, well, that's a hell of an achievement!
