Do automobile journalists ever put their cash the place their mouth is? On a regular basis, we see automobile journalists say, “You should purchase this automobile!” or “I’d purchase this automobile 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 automobile, and I stored pondering again to at least one I reviewed final 12 months the place I bear in mind saying, “I’d purchase this automobile.”
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 overview for BMWBLOG concerning the automobile and whether or not it was nonetheless related six years after the G20-generation 3 Collection 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 could be a guide sports activities automobile I may take to the monitor and revel in a spirited drive within the stunning canyon roads round Southern California. The opposite could be an EV or environment friendly each day commuter I may use to get round for all of the driving I do each day—comfortably and with out many issues.
Nevertheless, the dream of an M2 and an EV obtained reduce quick once I switched jobs. Instantly, the EV I had as an organization automobile was gone, and I used to be in want of a brand new commuter automobile. However the dream of a sports activities automobile I may 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 house and dropping my two-car storage, I wanted one automobile to do the whole lot I used to be on the lookout for. I wanted one automobile for all of my 50–100+ miles of each day driving, and a automobile I may 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 last word go-to for that one-car answer for fans. They provide all of the practicality of a sedan in relation to type issue whereas providing elevated ranges of efficiency near that of a devoted sports activities automobile. Whereas they aren’t probably the most environment friendly or the highest-performance vehicles, the mix of the 2 is what makes them such compelling selections for fans who desire a sports activities automobile however could not be capable of moderately drive a devoted two-seat sports activities automobile 75 miles a day for years on finish whereas carrying baggage or passengers.
Since its introduction 50 years in the past, the BMW 3 Collection has lengthy been thought of the chief within the sports activities sedan section. The G20-generation 3 Collection is not 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 provide a barely extra luxurious trip or options, in relation to driving expertise and all-out efficiency, the G20 reigns supreme. Even if the opposite luxurious manufacturers have launched newer fashions over the previous few years, a number of updates have stored the G20 on prime. Particularly, I’m going to give attention to the M340i.
What’s New for the 2025 Mannequin 12 months
For 2025, the BMW M340i (and 330i) have acquired one other replace. The primary LCI (life cycle impulse) for the G20 happened 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 gentle hybrid system (though that was technically launched within the 2021 mannequin 12 months with the B58TU). For 2025, the automobile now receives one other set of updates which might be extra important than may first meet the attention.
For starters, there’s the revised inside. Now, iDrive 8.5 is normal, 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 couple of new colours are on provide, together with Arctic Race Blue (beforehand seen on the 4 Collection), and new wheel choices just like the 1038i and 995M wheels.
Crucial 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 gas 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, comparable 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, based mostly on quite a few dyno runs, are very underrated and far nearer to the ability on the wheels than on the crank.
The outcomes of those updates will not be 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 nearly no purpose to show it off (although the button to take action has returned)—and permits the automobile 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, basically gliding in impartial.
Roadtrip King
One of many necessities for my new automobile was that it needed to be good at long-distance street journeys. I like to go to buddies in Phoenix, Las Vegas, and El Paso. I additionally needed one thing I may drive coast-to-coast—from NYC to LA—in consolation and confidence (and this has completely nothing to do with a future Cannonball Run File 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 automobile 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 pondering again to Alex Roy’s E39 M5 he used to resurrect and set the Cannonball File: 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 practically similar in energy—with nearly 400 hp and 400 lb-ft of torque. However my rear-wheel drive M340i is over 100 kilos lighter than that M5.
The scale, type issue, and effectivity of the automobile made it the most effective cross-country vehicles I’ve pushed. The B58 fortunately zips throughout the nation at over 80 mph (with the movement of site visitors) whereas returning practically 40 mpg. And the circumstances weren’t even superb: temps ranged from 10 to twenty°F, with excessive winds and snowstorms. Usually, vehicles get their greatest gas 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 outdoors Memphis. That meant a number of idling to maintain the warmth operating, regardless of the delicate hybrid system’s greatest efforts. I additionally hit a significant pothole and didn’t notice I had a sidewall gash and bulge till 1,000 miles later. Thankfully, the Bridgestone Turanza All Season Run-Flat tires are practically indestructible. These low-rolling-resistance tires support gas economic system however nonetheless provide first rate grip—higher than anticipated, with out noticeably sacrificing efficiency.
The quiet cabin, clean trip, and driver help options made the freeway miles fly by. This really is a automobile constructed for the autobahn. I drove from Los Angeles to Washington, D.C. in beneath three days with minimal discomfort. My solely grievance? The seats may very well be extra supportive on lengthy hauls. However general, this is without doubt one of the greatest street journey vehicles on sale right this moment.
Canyon Carving
Regardless of how nicely this automobile 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 automobile likes to be pushed exhausting. The mounted 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 really damage dealing with, however this setup permits for simply sufficient journey to keep up grip.
There’s some physique roll, however I don’t thoughts it—it helps talk the automobile’s limits, letting me modulate brake and throttle to rotate by way of corners as rapidly as adhesion permits.
This automobile is way sooner within the canyons than it appears. The potent powertrain and exact dynamics let it tear by way of quick sweepers and hold tempo by way of technical corners. It’s able to operating with devoted sports activities vehicles, which is a large praise for one thing that isn’t a full M automobile. It truthfully seems 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 automobile is barely good for freeway cruising does it a disservice.
The Excellent Automotive for Me
After spending a lot time with the M340i I drove final 12 months—and understanding precisely what I wanted in a brand new automobile—I knew this was it. It’s enjoyable on a backroad. It’s sensible each day. I can hop in and drive cross-country with out hesitation. Certain, different vehicles could do sure duties higher. However few vehicles beneath $90,000 can do the whole lot I would like this nicely.
It’s really one of the vital well-rounded, enthusiast-focused, daily-drivable vehicles in the marketplace in 2025. The rear-wheel drive sports activities sedan is a dying breed in right this moment’s SUV-dominated world—and that’s an actual disgrace. This automobile is good, and each mile I placed on it simply makes me happier.
My final driving machine.
