230 or 240
The tradeoff is basically more power at a higher cost.
The 230 has a lot of turbo lag but it goes over 500 hi way miles on a tank of gas. The 240 has bragging rights and delivers more power to the road. It certainly depends on your history. For me the 230 is the fastest car I've ever driven so it meets any needs there. Coming from a faster car would be a letdown. And it depends on what you can afford. Must dig quite a bit deeper for the 240. If it's not in the garage when I look, will I replace it with a 240? Good question. |

Where did you get the impression that the 230 (2.0 L B48 turbo I4) has a "lot of turbo lag"?

...unless you enjoy/are sensitive to the more nimble feeling of less weight over the front wheels. I prefer that to two more cylinders.

That pretty much sums it up.
The 230i is a very peppy car. 0-60 in 5.5 is pretty quick. Comparing that to the mid range muscle cars of the 60's GTO's 442's and the like, it would easily compare in the street performance. My 1985 Corvette spec's at 0-60 in 5.7 and 14.1 in the 1/4 mile. That car was fast for the day and was way quicker than the cars sold from 1974 to the early 80's. Many of today's cars are amazing (in comparison) w/ times easily dipping to the low 4 second range and 1/4 mile time into the 12 second range. I came of of a 2015 C7 and wanted a car with a bit more "oomph", so I chose the M240i (and added a Dinan stage 1). In retrospect, for the way I drive, I could have bought the 230i and been just as happy. I just bought a 2019 Mini Cooper S (replacing our 2015 Mini Cooper S), and I find that car (with the JCW tuning kit installed on both) to be plenty fast for around town driving. I'd estimate I'm around 0-60 in 5.9 -6.0 range) and that is plenty. On the other hand, the M240i is a beast and can get away from you (just like my 2015 C7) if you are not careful when driving. Plenty of video out the with guys in overpowered cars putting the car into ditches and trees. I'd wager a 230i with a Dinan tune would probably be somewhere close to 5.0 or even 4.9 for a 0-60 time. That is quick when I consider my 1967 650CC Triumph Bonneville did 0-60 in 5 flat back in my mis-spent youth. |

I daily drive a 230. In the right mode for the traffic I don't experience turbo lag. With a 13.7 gallon tank even with 36 mpg you can't run it dry and reach 500 miles.
Love my 230, but my next one will be a 6 cylinder. |

My next car will be the 230
I've driven the 230 and 240 back to back over the same route that includes expressway and poor city roads. The 240 is a thrilling ride and worth the extra money from the power perspective. However, even in the comfort mode, the 240 is a much stiffer ride than the 230, too stiff for me to enjoy except on the better roads.

If you've never had as powerful of a car, I think you'll love the 230. I didn't drive the RWD cars as they aren't really in my area. But when it comes to the x-drive versions I will say the one place the 230 lacked was passing power on the highway, otherwise it is great around town. I do indeed feel a little turbo lag but most people probably wouldn't notice it. I recently added a Dinan Stage 1 V2 tune and it has fixed my passing concerns. I had a JB+ before and the car did not feel any better at the top end, just the low end of the RPM range. Depending on driving style both cars will probably get similar MPG, if you're always flooring it the M240 would get lower MPG but you'd always be excessively speeding if you were doing that.

I have not compared to the base steel suspension, but when the MAdaptive suspension in the Track Handling Package is set to the Comfort setting, I believe it is not stiffer and may be even more comfortable. It turns the 2 from my preferred Sport experience to the setting my wife finds acceptable.

+1 on the 235/40 suspension. Mine is way more comfortable than a previous 328 coupe with non-adaptive sports suspension, which was like a rock. I find the suspension to be a great compromise.

One thing to note on the topic of gas mileage is that the 6-speed M240i will not get 30+ mpg like the automatic will due to the short 6th gear. I'm not sure why BMW did this as I can't see 6th gear being used on any tracks and it only sacrifices good gas mileage on the highway. I'm having trouble remembering what cruising rpms were before my LSD upgrade, but I'm almost certain the LSD made things worse as I'm seeing 2500rpms or higher when cruising at 70mph. Luckily, I don't commute with this car and don't take it on the highways much, so not a huge deal for me, but it is still worth mentioning.

I don't find turbo lag in N20 or N55 except shift car to 1000 rpm and floor it. In the city the 4 cylinder would be more than enough, but if you autocross or track the car, always go for the bigger engine

For autocross, the 230 is just as competitive as the M240i due to the PAX differences. If you are after the fastest raw time, both are not that fast compared with many other cars you are likely to see at autocross.

70 MPH @ 2500 RPM is stock for the 6-speed. That's with a 3.08 diff; if you change the diff ratio, then you'll affect the RPMs at a given speed in any gear. Below are links to a couple of gearing calculators that can be downloaded. DiffsOnline's calculator allows for six speeds, but has limited editing. Bob Tunnell's sheet allows editing. It's set up for five speeds, and when I use it I start with 2nd gear. Tunnell's sheet also allows you to enter your tire diameter (instead of having it calculated as the DiffsOnline calculator does). DiffsOnline Gearing Calculator http://diffsonline.com/images/GearingCalculator.xls Tunnell Racing Gearing Calculator http://www.tunnellracing.com/gearcalc.xls This is Tunnell's sheet with my data in it. Note that the stock rear tire diameter on a staggered MPSS setup is 24.8". That makes a slight difference. The tire size (255/35-18 in this example) is not used in any calculations - it's just in the sheet for reference. This is the same data graphed:

Turbo lag
This is my first turbocharged car so the lag is really noticeable. Example: In comfort mode (usual for a DD) in 6th gear at 2000 rpm (watch the torque dial on the sport display) pedal to the metal, 2 to 3 seconds for torque to rise and stabilize. With a normally aspirated engine this takes about .1 second. Of course with an automatic tranny this lag is masked by the furious downshifting that will happen. And with a little upgrade in driving skill this lag can be accommodated with a stick shift. And with a little experience you don't notice it so much. |

Another reason is more of emotional rather than financial. I might a bit paranoid, I think this is the time to grab a small car with a 6 cylinder engine like m235/m240i, because they are less likely to be produced in the near future. The direction of travel in the automotive world suggests this

230 vs 240
Get the 230 with the tack package and take it to the track. SO MUCH FUN. once you feel comfortable turn off traction control and let it drift. even better.
