To anybody who was involved that electrification would damage BMW’s core sedans, all we will say is that this: You don’t have anything to fret about. The longer term seems brilliant, even on the single-motor finish of the spectrum, the place the rear-drive 2022 BMW i4 eDrive40 resides.
As its designation suggests, the i4 is an EV tackle the 4-series Gran Coupe. Its modern four-door sedan-esque physique is indistinguishable from its gas-powered counterpart’s and options the identical longer roofline, frameless door glass, and rear liftgate moderately than trunk. This totally works within the i4’s favor, because the Gran Coupe presents superior rear-seat area and higher cargo entry than any 3-series sedan. And it seems unbelievable besides. Moreover, the title i3 was already taken.
We have beforehand examined—and been mightily impressed with—the high-performance variant of the i4, the M50, calling it “an EV M3” as a result of, amongst different issues, it outaccelerated the final M3 Competitors we examined. The eDrive40 is the extra mainstream, inexpensive model, however in lots of ways in which makes it an much more compelling EV, to not point out a critical various to its gasoline-powered counterpart, the BMW 430i Gran Coupe.
ICE-Beating Efficiency
In distinction to the M50, with twin motors making 536 horsepower and powering all 4 wheels, the eDrive40 has a single rear-mounted motor that sends 335 horses to its rear wheels. Nonetheless, that simply outclasses the 430i, whose turbocharged 2.0-liter inline-four places out simply 255 horsepower. On the monitor, our eDrive40 scampered to 60 mph in 4.8 seconds and dusted the quarter-mile in 13.4 seconds at 106 mph. That makes it faster than a rear-drive Tesla Model 3 Lengthy Vary, which reached 60 mph in 5.0 seconds and crossed the stripe in 13.8 seconds at 101 mph. In the meantime, the final 430i we examined (admittedly a convertible, not a Gran Coupe; their engines are equivalent, and weight differs by little greater than 100 kilos) achieved 60 mph in 5.5 seconds and lined the quarter-mile in 14.1 seconds at 98 mph. Backside line: The one-motor i4 is sufficiently fast.
It seems to be even faster in real-world acceleration conditions, the place direct-drive and instantaneous torque (the 317-lb-ft peak begins at zero rpm and carries on to 5000) results in whole annihilation of the 430i, which should construct increase and kick right down to a decrease cog in its eight-speed automated earlier than it may head off in pursuit. The eDrive40 handles the 5-to-60-mph street-start check in 5.1 seconds, whereas the 430i wants 6.8 seconds. The rear-drive i4’s passing occasions of two.0 seconds from 30 to 50 mph and a couple of.9 seconds from 50 to 70 mph are much more telling, with the 430i requiring 3.4 and 4.0 seconds, respectively.
BMW i4 Vary Outcomes
It is not all about velocity. Vary, the opposite aspect of the EV coin, is an excellent greater concern to many, and right here the i4 eDrive40 handily outperforms the M50. Each i4 variants use the identical 81.5-kWh liquid-cooled lithium-ion battery pack, and as is typical in such instances, the much less highly effective single-motor automobile delivers better vary. For the eDrive40, that is an EPA-rated 301 miles with 18-inch wheels or 282 miles with the non-obligatory 19s, versus the M50’s 270 miles on 19-inch rolling inventory or simply 227 miles with high-performance 20-inch rubber.
Our eDrive40 tester was fitted with summer-spec Hankook Ventus S1 evo3 19-inch efficiency rubber, and it primarily equaled its 282-mile EPA ranking in our extra extreme 75-mph freeway vary check by delivering a 280-mile outcome. Our 75-mph consumption labored out to 107 MPGe, which simply surpassed the EPA ranking of 99 MPGe mixed (100 metropolis, 98 freeway). It will get higher: We averaged108 MPGe over the 1336 miles we had the automobile. This included 130 MPGe on a 158-mile random mixture of metropolis and freeway driving, the place mild visitors held freeway speeds between 60 and 70 mph. Our maximum-attack run on Angeles Crest Freeway was our worst “tank” at 85 MPGe, which maintained respectability as a result of routine freeway driving was a part of getting there and again.
EV Sounds and Regen Braking
Within the M50, we discovered the synthesized EV inside sound to be overbearing, however right here the IconicSounds Electrical (a aspect dish to the $875 Harman/Kardon surround-sound stereo improve, which you completely need) is much less noticeable and could be turned off anyway—the higher to benefit from the silence. Our eDrive40 emitted simply 64 decibels in each the 70-mph cruise and wide-open acceleration assessments, which just about means you are merely listening to hushed ranges of wind noise enveloping the modern bodywork.
We had been lucky to pattern two totally different eDrive40s on two totally different coasts. Each ran on 19-inch tires. One had the Dynamic Dealing with package deal ($1750), which incorporates Variable Sport steering, adaptive M suspension, and M Sport brakes, whereas the opposite had the usual brakes and glued dampers. The usual-spec automobile is the one which landed close to our West Coast testing grounds, so that is the one we examined. In each instances, brake regeneration is adjustable. A lateral slap of the shifter into the B setting represents an instantaneous shortcut to the strongest degree, however Drive could be programmed to ship 4 different ranges: low (coast), medium, excessive, and adaptive. Making that change requires delving into an onscreen menu, however with B at all times on the prepared, an proprietor is more likely to resolve on a favourite Drive setting early and toggle between the 2 with the shifter from there on out.
That max-regen setting within the M50 rises to the extent of one-pedal driving, however not so right here until you enable more room. Not like within the dual-motor M50, regen acts solely on the eDrive40’s rear axle. Everytime you add friction brakes midstream, you are immediately involving the entrance axle and initiating weight switch midstop. In sure regen settings, this may make the brakes really feel grabby towards the tip of a cease, significantly with the M Sport brakes, which have extra preliminary chunk and 14.7-inch entrance rotors as an alternative of 13.7-inchers. On the check monitor we engaged the bottom regen setting so the friction brakes did all of the work. The outcome was a 169-foot cease from 70 mph and 365 toes from 100 mph, with the usual brake setup displaying glorious management and completely zero fade.
On the skidpad, our eDrive40 orbited the circle to the tune of 0.87 g, a smidge lower than the 0.90 g we noticed in a 430i. However the i4’s steadiness is way extra impartial, to the purpose the place disengaging the steadiness management is an instantaneous ticket to an unofficial drift mode. We suspect the distinction boils right down to our check automobile’s 4699-pound weight, plus the usage of the identical 245/40R-19 entrance and 255/40R-19 rear tire sizes regardless of the eDrive40’s extra rear-biased weight loading of 55 p.c (versus 52 p.c).
On the street, each suspension setups really feel participating and nicely managed. The model with the Dynamic Dealing with Bundle struck the identical tone because the M50, with the adaptive damper system’s Sport setting offering sharp response and the Consolation setting offering simply what the title implies: agreeable daily-drive consolation. However the usual fastened damping of our West Coast tester did not really feel substandard, because it ingested all method of street imperfections with aplomb and pasted an enormous grin on our face once we pushed it laborious within the mountains. We additionally discovered its steering to be correct and predictable, despite the fact that it lacked the variable-ratio rack of the East Coast automobile.
Agreeable In-Cabin Tech
Inside, the driving setting is each bit as trendy, impeccably crafted, and logical because the M50, with the dearth of carbon-fiber trim not spoiling the temper one bit. Maybe that is as a result of our automobile was fitted with non-obligatory Vernasca leather-based seats ($1450) and the tech-fabulous curved-display display screen ($1000), which comes paired with a head-up show. It is simple to scroll by the varied menus utilizing the touchscreen instantly or the rotary controller, which stays a welcome technique of navigation each between and inside perform areas, equivalent to for choosing satellite-radio stations or looking for a cellphone contact.
The curved show is a prerequisite for the $1700 Drivers Help Professional package deal, as a result of the display screen hides a set of infrared driver-monitoring sensors, which permit the very succesful lane-centering characteristic to change into actually hands-free at 40 mph and under. Standing lights flip inexperienced on the steering-wheel spokes when the system is out there, however they will flip yellow as a sound it emitted if you happen to gaze drifts away or visitors velocity will increase past 40 mph. It really works brilliantly, nevertheless it definitely is an choice you’ll be able to skip in case your driving routine does not usually embrace visitors jams.
At a beginning determine of $56,395, the eDrive40 chops a hair over $10K off the worth of the M50. It is also about $10K greater than a gas-powered 430i Gran Coupe. However it’s eligible for the utmost $7500 federal tax credit score, which might usually be folded right into a lease deal even if you happen to do not qualify outright. Even with out that, the eDrive40 is totally definitely worth the premium. It is a unbelievable look into an electrified BMW future that does not depart followers of the model out within the chilly.
