Performance

The following table gives performance data for different specification V8s and from a variety of sources. All on normal (hard) road tyres unless otherwise stated. I have only included accurate data that is backed up with magazine road tests or timing tickets from the drag strip. Accelerometer data is not used.

0-60 times are not a very good indicator of a car's performance. Once you reach low 4s ordinary road tyres become the limiting factor. The times are also affected too much by the number of gearchanges made and they don't represent the range of speeds used when driving quickly. When driving fast how often do you drop below about 50mph ? Most time is spent between 50 and 100. Standing quarters are a much better indicator of a car's performance, but remember the following:

They still start from rest so driver technique is crucial.
Four wheel drive cars always get a better time than 2WD versions even though mid-range performance is normally identical.
Some magazines test 2 up and some don't. In a SEiGHT this will typically reduce the 1/4 mile trap speed by about 3mph and add 3 tenths to the time.
Owner-drivers are more likely to be mechanically sympathetic than a magazine tester. Also a magazine tester gets a lot more time to practice. I have rarely seen an owner-driver equal magazine test figures, they are usually about 0.5 to 1.0 seconds slower over a 1/4 mile.
Some magazines compensate for drag strip 'roll-out' when publishing times and others do not. What is roll-out ? At the drag strip the clock doesn't start until about 0.3 seconds after the car launches. Automatic timing equipment used by magazines usually starts as soon as the car moves. For an explanation of why, check out the Reaction Time Clinic.

If you don't have a drag strip nearby then a G-Tech Pro or an AC-22 is a handy tool that gives a pretty good indication of the car's performance if you use it properly.

If you have any more figures, especially from your own car, please mail them to me. If the figures are for your own car please let me know how the performance was measured, how much power the engine produces, and whether the car was on slicks or road tyres.
