Do automotive journalists ever put their cash the place their mouth is? On a regular basis, we see automotive journalists say, “You can purchase this automotive!” or “I’d purchase this automotive myself!” However generally that’s only a becoming tagline or sage recommendation that isn’t adopted up on. For me although, it was time to purchase a brand new automotive, and I stored considering again to at least one I reviewed final 12 months the place I bear in mind saying, “I’d purchase this automotive.”
It was April 2024, and I used to be fortunate sufficient to have simply gotten the keys to a 2024 BMW M340i xDrive in Melbourne Pink Metallic. I used to be doing a evaluation for BMWBLOG concerning the automotive and whether or not it was nonetheless related six years after the G20-generation 3 Sequence first went on sale. To not spoil the remainder of this text, but it surely was nonetheless very a lot related.
The One Automotive Answer for an Fanatic
Ideally, I might have two vehicles in my storage. One can be a handbook sports activities automotive I might take to the monitor and revel in a spirited drive within the lovely canyon roads round Southern California. The opposite can be an EV or environment friendly every day commuter I might use to get round for all of the driving I do every day—comfortably and with out many issues.
Nevertheless, the dream of an M2 and an EV acquired lower quick after I switched jobs. All of a sudden, the EV I had as an organization automotive was gone, and I used to be in want of a brand new commuter automotive. However the dream of a sports activities automotive I might take into the canyons or on a enjoyable street journey nonetheless felt so shut. With the potential of shifting right into a smaller one-bedroom condominium and dropping my two-car storage, I wanted one automotive to do every part I used to be searching for. I wanted one automotive for all of my 50–100+ miles of every day driving, and a automotive I might tackle lengthy street journeys and into the canyons for some enjoyable.
The Finest Sports activities Sedan
For many years, luxurious sports activities sedans have been the final word go-to for that one-car resolution for lovers. They provide all of the practicality of a sedan in the case of type issue whereas providing elevated ranges of efficiency near that of a devoted sports activities automotive. Whereas they aren’t essentially the most environment friendly or the highest-performance vehicles, the mix of the 2 is what makes them such compelling selections for lovers who need a sports activities automotive however could not be capable of moderately drive a devoted two-seat sports activities automotive 75 miles a day for years on finish whereas carrying baggage or passengers.
Since its introduction 50 years in the past, the BMW 3 Sequence has lengthy been thought of the chief within the sports activities sedan section. The G20-generation 3 Sequence isn’t any exception. Since 2019, the present 330i and M340i (lest we overlook the now-discontinued 330e, RIP) have been the benchmark that Audi and Mercedes have tried to surpass. Whereas some could argue the others supply a barely extra luxurious experience or options, in the case of driving expertise and all-out efficiency, the G20 reigns supreme. Although the opposite luxurious manufacturers have launched newer fashions over the previous few years, a number of updates have stored the G20 on high. Particularly, I’m going to deal with the M340i.
What’s New for the 2025 Mannequin Yr
For 2025, the BMW M340i (and 330i) have obtained one other replace. The primary LCI (life cycle impulse) for the G20 took place in 2022 and introduced with it the introduction of the brand new front-end design, iDrive 8.5 with the curved shows, and—for the M340i—a light hybrid system (though that was technically launched within the 2021 mannequin 12 months with the B58TU). For 2025, the automotive now receives one other set of updates which can be extra vital than may first meet the attention.
For starters, there’s the revised inside. Now, iDrive 8.5 is commonplace, with refined software program and a brand new look. The ambient lighting has modified, together with the up to date M Efficiency steering wheel. A number of new colours are on supply, together with Arctic Race Blue (beforehand seen on the 4 Sequence), and new wheel choices just like the 1038i and 995M wheels.
An important change is the introduction of the third-generation B58 engine. Nonetheless a 3.0-liter inline-six, it now options each port and direct injection to enhance gasoline supply and scale back carbon buildup on the consumption valves—a typical subject with direct-injection-only engines. The consumption manifolds have additionally been redesigned to permit for extra cooling, related in design to the S58. The electrical motor contained in the ZF 8-speed transmission has been up to date to supply extra energy and larger effectivity. The tip outcome? To cite James Pumphrey: “Extra powah, child.” Formally, it’s rated at 389 hp and 398 lb-ft of torque. These numbers, primarily based on quite a few dyno runs, are very underrated and far nearer to the facility on the wheels than on the crank.
The outcomes of those updates should not solely a small energy bump over the second-generation B58 M340i but additionally larger effectivity. The delicate hybrid system improves cease/begin operate—now so clean there’s virtually no motive to show it off (although the button to take action has returned)—and permits the automotive to coast extra successfully. In contrast to conventional transmissions that induce engine braking when off-throttle, this setup permits the engine to close off and the transmission to decouple fully from the driveshaft, primarily gliding in impartial.
Roadtrip King
One of many necessities for my new automotive was that it needed to be good at long-distance street journeys. I like to go to associates in Phoenix, Las Vegas, and El Paso. I additionally needed one thing I might drive coast-to-coast—from NYC to LA—in consolation and confidence (and this has completely nothing to do with a future Cannonball Run Document try).
Shortly after I purchased my M340i in January 2025, I took it in for a paint correction, full PPF and ceramic coating, together with ceramic window tint set up. The automotive was now prepared for a cross-country journey to go to my household in Delaware. It was nearly good for the job. The truth is, I stored considering again to Alex Roy’s E39 M5 he used to resurrect and set the Cannonball Document: 31 hours, 4 minutes from New York to Los Angeles. The G20 M340i is inside an inch of the E39’s wheelbase. It’s additionally almost an identical in energy—with virtually 400 hp and 400 lb-ft of torque. However my rear-wheel drive M340i is over 100 kilos lighter than that M5.
The dimensions, type issue, and effectivity of the automotive made it probably the greatest cross-country vehicles I’ve pushed. The B58 fortunately zips throughout the nation at over 80 mph (with the movement of visitors) whereas returning almost 40 mpg. And the circumstances weren’t even ideally suited: temps ranged from 10 to twenty°F, with excessive winds and snowstorms. Usually, vehicles get their finest gasoline economic system above 60 levels. So what was my common MPG for the 7,000-mile journey from LA to the East Coast and again?
34.6 mpg.
This wasn’t some hypermiling experiment, both. I hit 37 mpg on the primary leg, however a blizzard dropped a number of inches of snow on the return, shutting down the freeway for 4 hours exterior Memphis. That meant numerous idling to maintain the warmth working, regardless of the delicate hybrid system’s finest efforts. I additionally hit a serious pothole and didn’t notice I had a sidewall gash and bulge till 1,000 miles later. Happily, the Bridgestone Turanza All Season Run-Flat tires are almost indestructible. These low-rolling-resistance tires assist gasoline economic system however nonetheless supply respectable grip—higher than anticipated, with out noticeably sacrificing efficiency.
The quiet cabin, clean experience, and driver help options made the freeway miles fly by. This really is a automotive constructed for the autobahn. I drove from Los Angeles to Washington, D.C. in below three days with minimal discomfort. My solely criticism? The seats might be extra supportive on lengthy hauls. However total, this is without doubt one of the finest street journey vehicles on sale right now.
Canyon Carving
Regardless of how properly this automotive does on street journeys and commuting, let’s not overlook there’s nonetheless an M badge on the again. No, it’s not a full M3—however park it on a backroad and also you may second-guess that. The G20 chassis is extremely stiff, and in consequence, this automotive likes to be pushed arduous. The fastened sport suspension is ideal for mountain roads. It’s solely barely stiffer than consolation mode on the adaptive dampers—proper the place I’d need it. Too stiff on bumpy roads can truly harm dealing with, however this setup permits for simply sufficient journey to take care of grip.
There’s some physique roll, however I don’t thoughts it—it helps talk the automotive’s limits, letting me modulate brake and throttle to rotate by corners as rapidly as adhesion permits.
This automotive is way quicker within the canyons than it appears to be like. The potent powertrain and exact dynamics let it tear by quick sweepers and maintain tempo by technical corners. It’s able to working with devoted sports activities vehicles, which is a big praise for one thing that isn’t a full M automotive. It truthfully looks like a Toyota Supra in a tailor-made swimsuit. I’ve loved drives with track-prepped Miatas, GR86s, older Boxsters, and Civic Kind Rs. Saying this automotive is simply good for freeway cruising does it a disservice.
The Good Automotive for Me
After spending a lot time with the M340i I drove final 12 months—and realizing precisely what I wanted in a brand new automotive—I knew this was it. It’s enjoyable on a backroad. It’s sensible every day. I can hop in and drive cross-country with out hesitation. Positive, different vehicles could do sure duties higher. However few vehicles below $90,000 can do every part I need this properly.
It’s really one of the vital well-rounded, enthusiast-focused, daily-drivable vehicles available on the market in 2025. The rear-wheel drive sports activities sedan is a dying breed in right now’s SUV-dominated world—and that’s an actual disgrace. This automotive is sensible, and each mile I placed on it simply makes me happier.
My final driving machine.
