Welcome Tech in the Car I'm here at the Goodwood festival of speed let's talk about
the mcmurtry spieling and how it broke the record at goodwood at the 2022 goodwood festival of speed
the mcmurtry spieling is an amazing electric car which just broke the record at the goodwood
festival of speed on the hill climb with a time of 39.09 seconds driven by f1 and indycar driver
max chilton and it beat the vw idr record i drove the hill course earlier in the day
on thursday in the lamborghini hurricane evo and you can see my video on the channel so
i've driven up the hill climb course and not many people probably have done that
and i have to say it is a really tight course it's very very short even in a car which isn't as fast
as mercury it still takes about 40 seconds and it's over before you know it the straw
bales come up the wall come up and you're over the finish line before you even know what's happened
but i can only imagine what it was like doing it in the mcmurdry spelling
so the car is named after sir david mcmurtry and it's called the spearling because that's
irish for a thunderstorm and that's because the sound the fans make when you turn them on
and we talk about those fans in a second so what's the philosophy
of the car the philosophy of the mcmurtry speedling is about what could the future
of electric motorsport be and the way to achieve high range of speed in an ev
is about having to get the weight and drag down so you basically have to shrink wrap the car
around the driver this reduces the frontal area dimensions making an extremely slippery body shape
but even then you still need downforce for lap times because without downforce the car is going
to go all over the place so mcmurtry created a fan based downforce system like an inverse hovercraft
that creates downforce without needing a huge wing which also creates drag and slows the car down and
also drains the range and basically creates lots of reasons to slow the car down so this fan sucks
the car to the track and the car has no gears how this works is there's a skirt which lowers down
when you turn the fan on and it seals the air inside and then sucks it back out which is a
reverse of a hovercraft it has filters to clear all the air and get rid of the dirt so it doesn't
litter or damage other cars and those filters have to be changed when it's driving on a track
in terms of battery it's got a 60 kilowatt hour battery pack and the battery is in the side
pods and between the wheels they're all around the driver so the driver is safe and then they
add the batteries around it it's a twin motor rear wheel drive system with 1 000 horsepower
and you get full grip at zero speed so it can be applied straight away that's how it
can work with a rear wheel drive system with so much power that's 1 000 red horsepower per ton
if you think about a porsche 918 spider that produces 522 brake horsepower per ton
what this means is the wheels can spin up to 200 miles per hour in three tenths of a second
on this car and because the front wheels steer it's a pure driving experience but
of course it needs active suspension because those fans are sucking it under the ground
so it needs to have suspension to make it drivable and to give it that performance
in terms of performance it could do zero to 60 in less than 1.4 seconds even faster than
that zero to 186 miles an hour in under 9 seconds and its top speed is well over 200 miles an hour
the car is made from a fully carbon fiber design and it will be road legal the lights
need to be risen a bit and indicators added but eventually the mercury's feeling will be a
car that you can drive on the track and on the road and it will be a one-of-a-kind hyper car
