Hyundai Leans into EV Efficiency

Hyundai has each intention of constructing its future EV lineup thrilling. Its N Day occasion was all about alternatively fueled N efficiency.
Automobile and Driver was current for a Hyundai occasion in Busan, South Korea, this afternoon that the corporate known as “N Day.” The topic was efficiency, and the recurring theme was that Hyundai will completely not let efficiency fall by the wayside as electrification turns into ever extra deeply ingrained in Hyundai’s product lineup.
One manufacturing automotive was confirmed for the close to time period: a pure electrical Ioniq 5 N slated to be out there in 2023. We are able to’t present you the 5 N but, as Hyundai didn’t launch any particulars and leaves the look of it solely as much as our imaginations.
The RN22e and N Imaginative and prescient 74 ideas had been each characterised as “rolling lab” check beds. They are going to be used to refine electric-vehicle efficiency know-how that shall be utilized to future N choices. In Hyundai-speak, a rolling lab check mattress is the midway level between a pure purpose-built racing machine and a manufacturing automotive, so such automobiles mirror an intent to convey sure applied sciences to market.
The RN22e is an electrical sports activities sedan idea that’s primarily based on the Ioniq 6’s streamlined physique, E-GMP dual-motor platform, and 800-volt structure, with energy output bolstered to 577 horsepower and 546 pound-feet of torque, in step with the Kia EV6 GT.
Of the 2 ideas, the RN22e is extra of a near-term effort designed to probe the efficiency limits of the E-GMP dual-motor electric-car platform. It additionally comes throughout as a glimpse of what an Ioniq 6 N may appear like in the event that they resolve to make one. Its uprated motors and 77.4-kWh battery represents a considerable improve over the 321 hp and 446 lb-ft that the upcoming AWD Ioniq 6 will produce. The RnN22e’s motors aren’t simply extra highly effective, the direct-drive transmission has additionally been fitted with dual-clutch torque vectoring to not solely enhance agility and corner-exit traction, however to additionally discover the potential advantages of torque-vectored regenerative braking at turn-in.
It is also an consideration grabber, with a tall GT-style rear wing, a large rear diffuser, and a entrance grille that has been considerably opened as much as admit the additional cooling air this extra highly effective powertrain is prone to want. It crouches some 0.7 inch decrease than the manufacturing Ioniq 6, however what actually units it aside is that its entrance and rear fenders are considerably wider. These not solely symbolize an additional 5.6 inches of physique width and allow a wholesome improve in monitor width, they’re additionally stuffed stuffed with 275/35ZR-21 Michelin Pilot Sport 4S tires at every finish.
Just like the Ioniq 6, the RN22e rides on strut suspension up entrance and a multilink within the rear, however the bits are considerably completely different owing to its wider monitor and a a lot higher emphasis on dealing with. Its shocks are independently adjustable for compression and rebound, however there’s additionally a small quantity of top adjustability. The primary springs are standard-looking coils, however cutaways we noticed confirmed that every is mounted in step with a modest carry system. It is not but clear if that is meant to be a velocity bump/driveway clearance carry system, or a system that is meant to dynamically decrease the automotive at velocity. Because the characteristic seems at each ends, we’re banking on the latter. As for the brakes, the RN22e’s prodigious regenerative braking functionality is bolstered by four-piston monoblock calipers and 15.7-inch two-piece ventilated rotors up entrance, with extra pedestrian single-piston sliding calipers doing the deed out again.
We’re much more excited by the N Imaginative and prescient 74 check mattress, which is a two-seat, rear-drive 671-hp hydrogen fuel-cell/electrical hybrid sports activities automotive. Its mid-engine proportions call to mind the BMW M1 and Lancia 037.
Nevertheless, its angular wedge design aesthetic really connects again to the Giugiaro-penned 1974 Hyundai Pony Coupe idea that by no means noticed the sunshine of day. This wild-looking machine represents a extra long-term view of the place N-car powertrain growth may go, whereas additionally paying homage to the earliest days of Hyundai’s historical past. The quantity 74 refers to 1974, the yr that famed designer Giorgetto Giugiaro penned not solely the Hyundai Pony, an unremarkable four-door liftback that went into manufacturing in 1975, but additionally the Pony Idea Coupe, a bolder two-door design that by no means noticed the sunshine of day. The styling of the N Imaginative and prescient 74 is a contemporary tackle a automotive that by no means was, and it is a stunner from the longer, decrease, wider college of design. It measures 195.0 inches lengthy, 52.4 inches excessive, and 78.5 inches huge with a 114.4-inch wheelbase.
The N Imaginative and prescient 74 is a rear-drive two-seat sports activities automotive that is powered by a separate electrical motor on both sides. They staff up for a most mixed output of 671 horsepower and 664 pound-feet of torque, and since they’re unbiased the torque vectoring impact is produced by commanding asymmetrical output as an alternative of adjusting clutch pack strain. Hyundai’s claimed 60 mph acceleration of lower than 4 seconds looks as if a simple putt, however we expect there’s extra in it. They’re additionally focusing on a WLTP vary of some 600 kilometers, which interprets into 315 miles or so in EPA phrases . . . if we ever get to that time. That is, in any case, a “rolling lab” check mattress.
Electrical energy to energy these motors comes from two sources: a 62.4-kWh battery pack that may be charged as you’d any EV (full with the identical form of 800-volt quick charging functionality of the Ioniq 5 and 6), and an 85-kilowatt hydrogen gasoline cell that produces electrical energy on demand. Ostensibly, the gasoline cell is used to recharge the battery to increase vary whereas underway and to supply overboost when demand is excessive, however the staff may also discover deployment methods that can scale back the draw on the battery to handle its temperature in a spread of driving conditions, as much as and together with prolonged lapping on a racetrack.
Format-wise, the gasoline cell stack is mounted underneath the hood, with the T-shaped battery operating between and behind the seats. The dual motors are mounted low between the rear wheels, and a pair of hydrogen tanks sit simply above, a place that places them behind the seats and underneath the decklid. These tanks maintain 4.2 kg of hydrogen and will be refilled in simply 5 minutes. Big air intakes mounted behind every door cool the motors, the battery, and the ability electronics, and there is one other consumption constructed into the nostril that feeds a warmth exchanger for the fuel-cell stack. There is a large splitter up entrance to provide downforce and shovel air into the cooling system, whereas the rear finish is dominated by a tall wing and a full-width diffuser that attracts air out from underneath the automotive and thru the aspect vents.
Now that it has been confirmed, it is solely a matter of time earlier than we drive the brand new Ioniq 5 N. Efficiency and pricing particulars are being held again for now, however we should always know one thing nearer to the top of this yr. As for the RN22e and N Imaginative and prescient 74, the long run is a little more unsure, notably for the extra formidable N Imaginative and prescient 74. Our N-Day hosts did recommend that driving alternatives for each could also be within the offing within the coming months. Every time it occurs, we’re wanting to see how Hyundai’s tackle performance-minded EVs pans out.
