what cars can do over 60mph in 1st gear?

and interested to know reasoning for it??

cheers

Jaguar XJ-S V12 H.E just about manages 60mph in 1st.

3 gears (auto), 1:1 top gear, and a 2.88:1 diff ratio kind of limits it somewhat. LOL

120mph in 2nd gear too

Edit: Sad, but on paper I just calaculated it as a theoretical 70mph, but I know the gearbox force shifts just before that, even with the shifter locked into "1" (indicated 65mph).

None that i know of although a 3.0 Capri is close

I just wondering about any other cars out there like my old 78 corvette, its got a 3 speed auto, tall diff and 6.3L 500bhp custom built engine, I noticed Im getting well above 60 in 1st gear, I did the calcs on it and works out like this -
1st - 80mph
2nd - 132mph
3rd - 200mph(might need more power for this speed tho!)

Im thinking about fitting a shorter diff, to improve acceration, but that might lead to more wheel spin, plus im getting ready to fit a pro charger( engine has been built for supercharging), so this will mean more wheel spin!

thanks

Most bike engined kit cars will do 60 in 1st .

I believe the Jaguar XKR-R that was on Top Gear did 56 in 1st, but not sure whether this was ever put into production

Yep I think my Fury must be getting close to 50 - 60 in 1st, but I dont tend to look at the speedo when I give it full beans as I would end up in a tree!

I havent found a one day hire yet that would do it: although Ive tried them all...!

Yeah, I think lambo's do.

The new Corvettes have really long gearing, Z06, ZR1 do over 60mph in 1st and they still have 5 more gears to use (not like the 3 and 4 speeders above).
With lots of torque from the engine they can run long gearing.

Bikes get the high in-gear speeds because of the revs they can run at, an R1 or similar can do over 100mph in 1st.

Nope, my 3 litre managed 'just' 42mph in first. I'd agree with the murcielago and maybe the enzo hitting 60 or more in first

HaHa I know exactly what you mean! I built/run a 'blade engined Westie a while back, and that would just do 60 in 1st, but take your eyes off the road for a split second and you end up in a 360 spin!

Lamborghini Countach QV. At its launch it was a car magazine party trick to hit 60mph in 1st gear. This was revving it into the red zone though, so not something you should try too often. I thinked they usually timed about 4.8 seconds, which was considered ultra fast back then. Don't know what this would have risen to with a gear change though.

McLaren F1? Have vague recollection of reading somewhere that achieving 0-60 without a change up was a key design criterion. Might be wrong tho
