Lotus Elan EV (aka Elon) gets the @collectingcars_ cars excellent video treatment.
Size Matters !
Trying to break the 'arms race' "I need a bigger SUV than you, because me, mine and our stuff is SO important"
Not winning 🤷♂️

Wow - the motor on the left is the same as #LotusElon uses. The engine on the right would crush the lotus !!!
Engine Vs motor picture paints a 1000 words. Both produce 120hp. One is 54kg, 95% efficient, has one moving part & needs no maintenance. The other is 230kg, 30% efficient, has 100s of moving parts and needs regular servicing. @bobbyllew @Carpervert @QuentinWillson @elonmusk

In the Hyper9 Tau software there are 3 switchable regen and drive profiles, each are adjustable 0-100%. I dont use a clutch, instead I switch off regen witha button on the gearstick to change gear as the motor has low inertia and spins down gently with no regen.

Well tuned original Lotus Twincam IC engine Power and Torque specs overlaid with replacement Hyper9 E-Motor
Shows massive instant torque from zero, and also shows that it falls off with rev's and 'Voltage Sag' IS real
Similar overall performance delivered totally differently

The first questions many ask:
1. The weight: 'it must be heavier' ? Nope 20Kg lighter
2. The Range: 100 to 200 (free) miles (vs 23mpg !)
3. The Cost: £26K - selling fresh ICE motor paid for most EV parts
"From Elan to Elon .. a journey of adding lightness, quietness and efficiency"
1: Explaining my own 20+ year conversion (petrol to ev head) and Lotus Elan to Elon
2: Smart Thinking, Bad Crimps, ‘Brave Little Toaster’ and marriage planning for Elon .issuu.com/mark77a
50 years on and It's alive ! BlueTooth radio, combined with 4 regen options, #simpBMS display, Volts Amps, KiloWatts, battery temps and SOC, satnav / phone mounting (over ashtray / diagnostics)
Lowering 2 @Tesla modules to replace petrol tank, exhaust, large 12v battery and spare wheel - leaving a LARGER boot / trunk space than before conversion AND same weight
Got Interviewed By Ashton Kirby - about Elon
Lotus Elon
Fun lockdown project and hopefully EV mythbuster.
