It’s more of a design concept, most of the cars posted here haven’t had much suspension tweaking etc, mostly body design.
Here are the specs tho :
1995cc DI 16V VVL VVT I4, 263hp 323nm 27.62% efficiency.
5.5secs to 100km/h, 251km/h top speed
Double Wishbone - Multilink F/R suspension, Geared LSD & 6spd Manual Transmission
1473.3kg (Sport 2-seat interior, standard infotainment, all assists, standard 10s safety)
$18400 cost with no markup
As you can see, it’s pretty sporty but economical too, this was the concept behind it as most of the Betta designs.
You inspired me to try and design the Betta Lagunna E-Tron concept. It’s a plug-in hybrid, with a 100hp electric motor and a 115hp efficient 1.0T motor. I know it doesn’t look too much like an electric car but it still is slightly crazier than the average Betta design.
