The Lamborghini Sesto Concept ($TBA) is the latest instalment of lightweight supercar. With its advanced carbon fiber technology construction that gives it a curb weight of just over 2,200 lbs. — and that’s including its V10 engine and permanent all-wheel drive. And while the V10 outputs “only” 570 hp, that’s still good enough for a 1.75 kg per hp power-to-weight ratio and an insane 0-62 mph time of just 2.5 seconds.
