Puzzling Engines and Hyperwarps

[Sinocelt]

M5000 Void Engine ($66,600)
Mass: 1100
Soaks 9 Ship Ops, 9 Pilot, 6 Electronics

M5000 Void Engine EX1 ($63,000)
Mass: 980
Soaks 10 Ship Ops, 8 Pilot, 6 Electronics

M5000 Void Engine EX2 ($70,200)
Mass: 1189
Soaks 8 Ship Ops, 10 Pilot, 6 Electronics

1. Why is the M5000 Void Engine EX1 less expensive than the M5000 Void Engine?
2. Why is the M5000 Void Engine EX1 apparently better (same total soak, much lesser mass) than the more expensive M5000 Void Engine EX2?

3. Why is the M3200 Hyperwarp Ex apparently better (better soaks, lesser fuel cost) than the more expensive M3400 Hyperwarp?
