Reviews the 2012 Infiniti G25

2012 Infiniti G25

You don't see many luxury automakers shooting for a more affordable entry price, but that's what Infiniti did with its G Series when it added the G25 model. The G25 comes with a weaker V-6 engine, but everything else is essentially the same as the G37 — except the price, of course. The G25 shaves off nearly $4,000 compared with the G37, yet its performance is still spritely, says editor Mike Hanley. That's good, too, considering that the smaller engine doesn't help gas mileage much.

2012 Infiniti G25 Review



wow, a much more positive review than the similarly priced regal GS got. The 270hp GS was criticized for not feeling fast enough for a sports sedan, but this 218hp G25 was lauded for more than adequate power. How does that work? As for the styling, I honestly dont see what the author sees- this is one of the more mundane styling excercises in its class. The smaller wheels only add to that.

I would assume because the G25 is the low-end of the line in terms of performance and the Regal GS is the high-end. Makes sense to me why they wouldn't be apples to apples.



I will state the obvious- you dont compare cars like this based on their hierarchy within their lineups but on price. A G25 with its only option package is about the same price as the Regal GS. When you break it down to monthly payments you are talking about a few dollar difference per month. I cannot understand how the acceleration in the GS (timed at 0-60 in 6.2 secs) was underwhelming but the G25 (timed at 7.5 secs) is considered plenty powerful. The G25 is possibly the slowest sports sedan in this price range. Even the TSX 2.4L is slightly faster.


Very few people buy manual shift transmissions. Now with the V6 available in the TSX, the volume of manual shift 2.4 TSXs is less. The 5 speed auto TSX is slow, but gets better mileage. (due to taller gearing)

Real world usage. Tall gearing + turbocharger latency means the Regal GS doesn't feel like a sports sedan.

Small wheels are better than big wheels.



The TSX 2.4L auto is rarely tested but its probably about the same as the G25. The TSX with the stick is good for a 0-60 in the 7 sec range. As I said, there arent any $34k sports sedans out there that are really slower than the G25. Even the new 201hp C250 does 0-60 in under 7 secs. GS doesn't have much (if any) turbo latency, its a DI engine with twin scroll turbos- modern turbos have much less lag than older cars. Larger wheels fill out the fenders and on today's luxury cars 17" wheels are quite modest. Especially on a car like the G which lacks any visual distinction.


Ah, no. Honda is not only deficient one gear behind the standard of six, they are two behind Nissan. Also the gearing is tall for a 5 speed automatic (call it a 4.5 speed). Shift points for the TSX auto: 40,70,110, top speed occurs in 4
G25: 30,50,85,125, top speed in 5th
If in drive, and you floor it at 65mph, you aren't getting 2nd in the TSX, which means piddling acceleration. G25 finds/gets 3rd, and rockets away!

Smaller wheels are better. They are lighter & improve the ride on the crumbling infrastructure. Reducing wheel & tire weight pays off threefold: Unsprung weight, linear weigh to be accelerated, rotational weight to be spun.


There is no such thing as a 4.5 speed transmission.



In the year 2012 suspension and tire technology has advanced to the point where cars with 18, 19 or even 20" wheels ride pretty well. The Camaro has 20" wheels on some models but still rides well. Many luxury cars have 18" or larger wheels and ride well. On the G25 the smallish wheels make the car look somewhat weak and forgettable. Cars with few distinguishing features could use larger wheels. The Infiniti M is a car that looks totally forgettable without its larger, more aggressive optional rims.

I dont care about the TSX one way or another, my point is its one of the only other cars in the $33k price range that is even close to being as slow and modestly powered as this G25 which impressed with its potent 218hp engine. 218hp is plenty as long as its not an American car apparently.


chubby. I was making a point.
When you move from a 4 to 5 speed automatic, you split your gains; half to performance, half to mileage.
Honda's shift points of their 5 speed auto match that of an aggressively geared 4 speed automatic.
Honda favors mileage over performance.

Way back, when Honda upgraded the Acura TL from the '99 MY to '00, a 5 speed auto replaced the 4 speed auto. The car was only marginally quicker in the 1/4 mile, by about 0.5 second. The mileage did improve from 19/27 to 19/29. If Honda would have had a more performance oriented change in gearing they could have achieved 20/28.
