A Seven weighs in at about 1,200 lbs, so the battery could be smaller for similar range and performance. Battery tech does improve, specifically Wh per kg. The
original Roadster had 117 Wh/kg,
today we're at around 300 Wh/kg. This would mean a 50 kWh battery would weigh 166 kgs instead of 427 kgs. That's on par with engine/transmission/gas.
