Vehicle2003 MG TF
A fun british convertible from the early 2000s
I take inspiration from Neil Hutchinson's 2000 MGF ( WebPage ) and Mark Newell's conversion of another MGF (WebPage )
MotorSiemens 1PV5133-4WS20 3-Phase AC
Old, heavy - but rock solid and overbuilt looking at its ratings.

Rated for 35kW continuous, but as it is liquid cooled, I would anticipate being able to push this a bit.
DrivetrainCurrently the stock 1.6L K-series Rover engine & gearbox.

When converted, it will be powered by a Siemens Ford Ranger motor & Siemens Simovert 6SV 100kW inverter.

Batteries376 EIG ePLB CO20B 20Ah cells, 3.70 Volt, Lithium-Ion
Have purchased new batteries, originally
sourced by the now-defunct Detroit Electric for their SP.01 car.

Paired with an Orion BMS2 for battery
management and charger control.
