By means of the years, electrical automobiles have earned a repute of being fairly beige. The complaints of earlier technology electrical autos with lack of throttle or steering response have been seen as a sacrifice within the identify of gasoline financial system, however have been largely the product of technological limitations felt by early EV growth. That’s not the case anymore, particularly as battery expertise and electrical motors have advanced to create energy vegetation able to outrunning even the quickest automobiles on the street right now.
Croatian automaker Rimac is aware of this and has been specializing in constructing highly effective battery-powered automobiles since 2009. On June 1, Rimac lastly revealed its newest gasoline slayer to the world—and it boasts among the most spectacular efficiency stats to ever hit the pavement.
Meet the Rimac Nevera, the 1,914-horsepower hypercar named after a Mediterranean storm and destined to demolish velocity data all over the world.
Utilizing 4 hub-mounted electrical motors—one at every wheel—the Nevera generates a whopping 1740 pound-feet of mixed torque. Not like a gasoline engine, the hypercar’s electrical motor produces this torque immediately with out ready for a turbocharger to spool or for an engine to rev to its peak effectivity.

The excessive energy output mixed with the instantaneous torque of an electrical motor implies that the Nevera can speed up at an alarmingly quick fee. From a cease, Rimac says, the automobile can attain 60 miles per hour in simply 1.85 seconds. That successfully makes it the quickest accelerating manufacturing automobile to-date, outpacing the Koenigsegg Gemera and Bugatti Chiron Tremendous Sport.
If the motive force retains the accelerator pressed, the Nevera will hit 100 MPH in solely 4.Three seconds and 186 MPH in 9.6. 1 / 4-mile dash will take a modest 8.6 seconds.
Energy is simply half the battle. The Nevera not solely must pack a robust punch, but in addition must be as light-weight as attainable to fight the load of its battery pack. To realize this, Rimac makes use of light-weight carbon fiber to assemble the hypercar’s monocoque—the single-piece exoskeleton of the automobile answerable for the chassis’ structural rigidity. The monocoque integrates a bonded carbon fiber roof, carbon fiber rear subframe, and the automobile’s carbon-encased battery pack to type the one largest carbon fiber construction used within the automotive business right now. Your complete automobile weighs in at 4,740 kilos, 440 lbs of which will be attributed to the monocoque itself.
All issues thought of, that’s fairly common so far as electrical automobiles go. As a body of reference, the Tesla Mannequin S Plaid weighs in at 4,766 lbs, whereas BMW’s upcoming i4 M50 electrical efficiency sedan ideas the scales at 5,049 lbs.
When in comparison with a gasoline-powered hypercar, the Nevera appears pretty heavy. The Bugatti Chiron, a fairly bloated hypercar, can weigh round 4,358 lbs. A extra modest Lamborghini Aventador is simply 3,472 kilos—however neither of these have 6,960 particular person battery cells alongside for the journey.
Talking of batteries, Rimac says its 120 kilowatt-hour pack makes use of 21700 cells (the identical type issue battery cell discovered within the Tesla Mannequin Three and Mannequin Y). The pack is poised to ship a powerful 340 miles on a single cost. When depleted, Rimac claims the automobile can make the most of 500-kilowatt quick charging to achieve an 80 % state of cost in simply 22 minutes.

Fashionable electrical automobiles not solely output energy to their motors, but in addition use those self same motors to return energy to the battery pack when coming to a cease or coasting down a hill. This expertise, known as regenerative braking, makes use of the resistance of the electrical motors to decelerate with out making use of the automobile’s precise brakes and, in-turn, trickles a cost again into the battery pack. Each charging and discharging a battery rapidly generates an incredible quantity of warmth, so to maintain temperatures elective, the Nevera will detect if the temperature of its battery pack is climbing too excessive. In that occasion, the automobile can lower the regenerative braking fee in favor of utilizing the drive of its bodily brakes.
Vary and efficiency are each affected by a automobile’s aerodynamics. By lowering drag, a automobile could obtain higher vary. Proportionally rising downforce in key areas of a automobile’s bodywork can enhance drag, leading to decreased vary however higher maintained velocity all through a nook. Whereas this can be a problem confronted when designing any new automobile, it’s a considerably extra essential element to refine in an electrical automobile that may’t simply replenish on the pump like its gasoline opponents. Rimac engineered an answer by making use of the idea of energetic aerodynamics into the Nevera’s bodywork.
Lively aerodynamics work by modifying elements of the automobile’s design so as to change how the automobile responds to forces like carry and drag that air exerts onto a automobile throughout driving. The driving force can choose a selected driving profile (like Observe Mode to unleash the automobile’s full energy, or Vary Mode to preserve cost on a calmer drive) and the Nevera is programmed to bodily transfer its bodywork to regulate its response to those forces. Rimac in-built changes to the profile of the hood and a flap discovered on its underbody. Moreover, the rear diffuser and rear spoiler can shift place, which means that the Nevera can actively alter how a lot drag and downforce is being skilled at any given time. When the motive force is aiming to maximise vary, the automobile can have a decrease drag coefficient, and when placing energy to the pavement is the precedence, the automobile will have interaction excessive downforce mode.
Utilizing the Nevera’s onboard sensors, Rimac is ready to introduce a characteristic it calls “AI Driver Coach.” This Nvidia-powered machine studying system makes use of 13 on-board cameras, 12 ultrasonic sensors, and 6 radars to evaluate a driver’s talent on the monitor. The system can then present auditory and visible suggestions to enhance steering, braking, and acceleration patterns. Rimac says that the Driver Coach characteristic gained’t ship with the Nevera, however will as a substitute be obtainable as an over-the-air replace in 2022.
Rimac will construct simply 150 Neveras on the market across the globe, and every purchaser will get an unique invitation to the Rimac facility in Croatia to design their automobile to their precise specs. That degree of customization shouldn’t come as a shock given the automobile’s price ticket: every unit is priced at an eye-watering 2 Million Euros ($2.44 million USD).
