BMW 3 Series: Which is Best?
Diesel, Hybrid, All-Wheel Drive...
With a Rich Lineup, Which 3 Series is Right for You?
In October 2011, a full model change, the first in about seven years, was announced.6th Generation BMW 3 Series is, as a flagship model forBMW, and in Japan too, since the launch of the328i, it has been followed byhybrid,4WD,diesel,Touring, with power sources, drive systems, and body styles being introduced one after another. Currently, the lineup is structured to offer finely tuned models according to user needs. This new BMW 3 Series boasts the richest lineup ever. Which is truly the best buy? Here are the insights from the familiar Mr. Tatsuya Otani.

What is the 3 Series Now?
The 3 Series, which forms the backbone of BMW, is rapidly expanding its lineup. The following summarizes the flow of the 6th generation 3 Series (F30 series) that debuted this year.
January 30th328i Debuts
April 9th6-speed Manual Added Simultaneously with 320i Debut
July 25thActiveHybrid 3 Debuts
August 8th320i xDrive Debuts
August 22nd320d BluePerformance Debuts
September 5th3 Series Touring Debuts
This is a rapid succession of model introductions, but let's highlight a few key points to understand about the new 3 Series.
1) The Japanese specification 3 Series is equipped with a 4-cylinder turbo engine in almost all models. The exception is the ActiveHybrid 3, which combines a 3.0-liter inline 6-cylinder TwinPower Turbo engine with an electric motor.
2) The maximum output for the 328i and 320i is 245ps and 184ps respectively, but they are essentially the same engine tuned differently; the base 2.0-liter inline 4-cylinder TwinPower Turbo engine is common to both.
3) Each model is available in five trim levels: Standard, Sport, Modern, Luxury, and M Sport. However, the Sport, Modern, and Luxury trims differ only in interior and exterior styling, while the suspension and tire sizes are the same. The prices are also identical.
4) The 6-speed manual transmission is only available for the 320i sedan.
5) The 3 Series' xDrive is notable for being the first right-hand drive BMW sedan with all-wheel drive. However, it is only paired with the 320i sedan.
6) The Touring wagon body style is exclusively paired with the 320d and 328i.
These are the basic rules to consider when looking at the new 3 Series, yet the number of choices is still more than sufficient. Therefore, we will focus on the recently added powertrains to help you choose the ideal 3 Series.

What is BMW's Hybrid System?
First, let's look at the "ActiveHybrid 3," the only model in the new 3 Series lineup for Japan that is equipped with a 6-cylinder engine.
In Japan, hybrids are often associated with fuel efficiency, but German car manufacturers likeBMWtend to view hybrids as "high-performance models with good fuel economy."
Press releases emphasize its high performance, such as a system output of 340ps and a 0-100 km/h acceleration time of 5.3 seconds. Regarding the price, it's presented as a "mere 130,000 yen increase over the previous generation 3 Series high-performance model, the '335i,' at 6.99 million yen."
Furthermore, it boasts zero-emission driving in EV mode and fuel efficiency comparable to a 4-cylinder gasoline engine (16.5 km/ℓ in JC08 mode, same as the 320i).
However, the impression from test driving was somewhat different from the previous generation 335i.
While the 335i, with its direct-injection turbo engine, delivered powerful acceleration thanks to its thick low-to-mid-range torque, the ActiveHybrid 3's engine revs more freely, smoothly and progressively building speed.
As a result, the ActiveHybrid 3 offers a natural acceleration feel, reminiscent of the previous generation's naturally aspirated inline 6-cylinder engine, the "325i." However, when fully throttled, the boost function engages, unleashing the full system output of 340ps, delivering performance that rivals, if not surpasses, the previous generation 335i.
As mentioned, the ActiveHybrid 3 is the only model in the new 3 Series lineup equipped with an inline 6-cylinder engine. It was genuinely pleasing that it retains the "straight-six" character that is a BMW tradition. Unlike the somewhat gruff tone of the previous 335i, its light and clear exhaust note is also a welcome characteristic.

The Latest F30 Series: 328i, 320i, and 320i xDrive
BMW'sall-wheel-drive system, called "xDrive," is exclusively offered on the 320i in the new 3 Series. The 320i has recently been evaluated as having a light front end but lacking in performance, with a somewhat unrefined 4-cylinder engine. However, the F30 series 320i, also a 4-cylinder but with direct injection turbo, delivers ample torque from low RPMs, offering performance comparable to the 328i in most situations.
Furthermore, in terms of noise and vibration, it has been refined to the point where the disadvantages of a 4-cylinder engine are no longer noticeable. Considering cost performance, it is arguably a more recommendable model than the 328i.
Naturally, there are no complaints about the performance or refinement when paired with xDrive.
Moreover, during our test drive, which took place in the rain, the traction provided by the all-wheel drive was reassuring, allowing us to confidently navigate the winding roads of Hakone.
The benefits of all-wheel drive are not limited to good traction. Unlike 2WD vehicles, where handling characteristics change significantly when the drive wheels begin to slip, with 4WD, the cornering trajectory remains almost unchanged even with some skidding. This allows for confident high-speed cornering even in wet conditions.
The only drawback might be a slight compromise in the steering feel, which is typically rich in information for BMWs, due to power being sent to the front wheels. However, this difference is very minor. The advantages of all-wheel drive far outweigh this. The price, starting from 4.8 million yen, is also attractive for a BMW all-wheel-drive model.

The Surprisingly Refined Diesel Model - 320d Touring
Finally, we introduce the 320d BluePerformance Touring. This model is surprisingly well-executed.
BMW'sdiesel models, such as the "X5 xDrive35d BluePerformance"equipped with a 3.0-liter inline 6-cylinder engine, have already been introduced in Japan. However, compared to the X5, which tends to favor high RPMs, the 320d, true to its diesel nature, produces abundant torque at low RPMs, offering excellent drivability.
Its highly linear response to throttle inputs is another strong point. Furthermore, the absolute power is sufficient, and the responsiveness is excellent, so there was no feeling of being held back even when driving aggressively on tight winding roads.
Additionally, the body rigidity is remarkably high, and the slightly firm suspension setting is exquisite, providing a sense of unity as if you were controlling the car with your palm.
It may come as a surprise, but in terms of being able to drive the car exactly as you intend, the 320d BluePerformance Touring we tested is the best among the new 3 Series models.
The exhaust gas treatment technology, which meets post-new long-term regulations using only a combination of a diesel particulate filter and a NOx storage reduction catalyst, without employing a urea SCR system, is also noteworthy.
The effect of not using a urea SCR system must be significant in achieving the low price of 4.91 million yen, even for the Touring wagon body style.
For the same reason, the fact that there is no need to replenish urea, making it virtually maintenance-free, is an undeniable advantage.
The new 3 Series boasts a diverse lineup, including the 328i, 320i, ActiveHybrid 3, xDrive, 320d, and Touring models. Although I started writing this article to help readers choose a model, I now deeply regret that by detailing their charms, I may have ended up confusing them even more.
