With that said, let's move on to the coupe's specs. Delta Motorsport is a British engineering consultancy born out of competition. Expected to be priced at $115,400, Delta calls the E4 Coupe an ultra-low energy vehicle and with its 190-pound carbon composite chassis, it's lightweight (2,150 pounds), too. The E4 Eco (a sport version will supposedly be built at a later date) features a 32 kilowatt-hour lithium-ion battery pack and twin Oxford Yasa Motors that crank out up to 553 pounds-feet of torque each. The E4 Eco reportedly hits 60 miles per hour in 6.5 seconds and tops out at 116 mph. Range is estimated to be a solid 140 miles. As of right now, the E4 is only a prototype and Delta has yet to commit to a launch date for this electric coupe. Hat tip to Paul!
