Rimac Automobile sets acceleration records with their 11 second all electric E30 3-Series BMW, Announces Concept_One vehicle

The last time we saw this all electric E30 from Croatia it was running low 12's in the 1/4 mile and seen spanking a Tesla Roadster as well. The car now develops 600 horsepower and 663 pound-feet of torque which propels it through the 1/4 mile in 11.8 seconds although no trap speed is given. It hits 60 miles per hour in 3.3 which according to the FIA makes it the fastest accelerating electric vehicle in the world although that is likely because other electrics have not set records with the FIA.


A record is a record however and this is impressive. Officially, the car holds 5 electric acceleration world records:

• 1/8 mile: 7,549
• 1/4 mile: 11,808
• 1/2 km: 13,714*
• 1 km: 23,260*
• 1 mile: 35,347*

If this is not impressive enough, Rimac is also producing an all electric sports car with 1000 horsepower called the Concept_One. The specifications are lofty with 1,180 pound feet of torque, a carbon fiber body, and proposed 300 mile range. Will they pull it off? Who knows, building a fast electric E30 is a bit different from designing an electric supercar. It does look promising and hopefully they pull it off.
