For a 3.7l 280 bhp roadster on 6th gear, a french forumer measured with GPS 61km/h (38 mph) @ 1000 rpm. Theoretical computing deduces 214 km/h ( 134 mph) @ 3500 rpm.
First test of an AR P4 in 5th gear 39 km/h (25 mph) @ 1000 rpm. The car has a 3.91: rear axle and probably the standard MAZDA gearbox of the PLUS 4. To be confirmed. Theoretical computing deduces 201 km/h ( 134 mph) @ 5150 rpm.
Some figures, speed at 1000 rpm on the last gear:
Roadster: 61 km/h (38 mph)
PLUS 4 2005: 40.4 km/h (25 mph)
AR P4 : 39 km/h (24 mph)
Ferrari Modena: 34 km/h (21 mph)
Ford PUMA: 32 km/h (20 mph)
cerealsurfer racer: 32 km/h (20 mph) TBC
Probably with all the standard Morgan, maximun speed will be reached on second last gear.
