2011 Infiniti G25 Will Get Turbo 2.5-Liter at the 2010 Detroit Auto Show

yeah, but the BMW inline-six is sweet to rev. I'd have a hard time choosing a turbo-four over it, with lower output.

For price, they already destroy the bmw 328i. They already compete at the same base price having 98 more horses!!!! Absolutey gets smashed in the head, no chance in perfomance. For $40k u get basically a very close perfomer to bmw`s $50k 335i.
That is of course, optioned as they should be.
Now this numbers of this turbo engine are very low, poor indeed. Only 210 horses? only 195 of torque? From a turbo V6? LOL crap
They should tweak it for more for the USA market.

Actually it's a V6:
http://en.wikipedia.org/wiki/Nissan_VQ_engine#VQ25HR

But still, I think that this move would be a waste-but that's just me.....

@jederino- It's a turbo 6, not a turbo 4, but I would still take the inline 6 anyday.

I will add to the previous critiques; Subaru has had a turbo 4(2.5) with at least 240+ hp available for what...5 years now (05 model Legacy GT)? Now, if they are doing the lower hp/tq numbers for FUEL efficiency, so that the entire line is lifted on numbers, OK, but I won't be in line for one of these.

This is a pretty smart move. Especially since they probably decided not to go after the 1 series with a car slotted between the 1 and 3 (just like the G is, in size, in the middle of the 3 and 5). I'd have preferred a smaller Infiniti myself, but if this comes in at the right price, they can draw buyers from the 328 and also get some people to up-buy from the upcoming FT86.

I'm a fan of almost all inline-six motors. Hence the name. :)

But to add to Perrito, The WRX 2.5 turbo offers 265HP and 244 lb-ft...

I had an 08 WRX and now a G35 coupe, I get the same mpg average (22) in both cars. I still think Nissan needs a RWD coupe/sedan to compete with the 1-series or maybe the new Ft-86.

Actually for the numbers we have above, they are the number for the NA engine.
The turbocharged VQ25 should be rated around 270hp-280hp and a margin
lower torque compared with VQ37.

^^
thats a good deal better

I'm sure there'll be plenty of tuners out there ready to make this a 300+ hp engine.

2.5 liter turbo V6? Why not turbocharge an inline 4? This is odd. How can a turbo V6 only turn out low 200's hp? It's almost like everything in this article makes sense except they meant to type I-4 instead of V-6. I believe IL though. All I know is my close friend has the 306 hp V-6 (2008) and it is truly a joy to drive - Eager/strong motor, slick looking, great exhaust note, no body lean in corners, tenacious grip from the B'stones, smooth ride when just cruising, tan interior with wood trim looks very upscale, etc. Amazing car worth 10k more than they charge. I believe it is the best sports sedan for the money in the entire industry.

@yuenchiu6

Thats so true, this turbo VQ25 will be just about as fast as the 328i for far less money. Good move Infiniti:)

I thought its a 2.5 turbo V6. And Nissan is being rated as BMW in the East. With weight could be less than a 328i, G25 maybe something that makes BMW to put more turbo cars out their. Like putting one turbo instead of two for the 328i.

inlinesix says:

I agreed Nissan should consider a Silvia again.

why would you turbo a V6 to get 210hp? That is pathetic. You can get 263hp in the MS3 with 2.3L and 260hp from the 2L in the Cobalt/HHR SS. They better increase output by about 40hp before they bring that to the US. That power in not acceptable for a RWD sports sedan costing over $30k.

Not a bad idea but like they said, 210HP for a turbo V6 seems low. The VQ30 had similar specs but at the same time if it gets high 200's HP and TQ, it might start taking a chunk out of the G37 sales.

Still, I am curious to see how well it will perform and also the price. Infiniti doesn't cost a ton with options but it's easy to get it up there with the right options.

1487, Wizard:

The turbo 2.5L V6 VQ25DET from Nissan is listed at 280 hp @6400 rpm and 300 ft·lbf (410 N·m) @3200 rpm.

210 horsepower is PATHETIC for a turbo V6

Manual or no Manual? That's the question.

The same reason GM puts the garbage 3.0 in as a base motor in most of their Cadillacs now, to meet pie in the sky CAFE standards.

The weaker engine will satisfy image buyers who shop sheetmetal and not performance.

Its existence lets them segment their lineup to bundle overpriced options into trims with the good motor and charge a ridiculous markup. Big profit from the enthusiasts who want it, big push towards the CAFE minded trims for anyone on the fence.

The good motor in the CTS is now a $2500 option that requires $5000 in other options. Expect Infiniti pricing to be similar.

if that's the NA engine, rated at 200 HP than that's more logical. Hopefully the 2.5 turbo will be at least 240hp. Infiniti needs to provide the fastest engines for the dollar, as theyve been doing

Where did this picture come from? Is it just an illustration or is this actually what the refresh is gonna look like. I think it looks pretty good.

I have a 335 and the inline configuration is great. But I6 is going to be harder and harder to pass emissions standards with all the piping being used. I wouldn't doubt you see a BMW V6 soon.

And I just picked up a G37S Convertible. I can feel the harshness at redline but it's not as bad as many say.

Edmunds must have goofed on the numbers or on their info.

The existing VQ25DD makes 210 PS (150 kW; 210 hp) to 215 PS (158 kW; 212 hp) @6400 rpm and 195 to 199 ft·lbf (264 to 270 N·m) @4400 rpm

That is the naturally aspirated engine in the current 250GT.

The only turbocharged 2.5VQ to ever exist was on the rare hopped up versions of the older generation Stagea. It is no longer made.

That engine made 280 PS (210 kW; 280 hp) @6400 rpm and 300 ft·lbf (410 N·m) @3200 rpm back in 2001.

So either Infiniti is bringing over the naturally aspirated version and Edmunds got the info wrong, but the numbers right are correct.

Or else Edmunds heard that Infiniti is bringing over a turbo 2.5 VQ and then pulled some numbers from the Japanese site thinking they are for the 2.5 turbo.

I'd be curious what the case actually is. It's the difference between somewhat interesting and FTW!!!

Its amazing how many people comment without reading.

I'm really surprised that nobody has called this a glorified Altima, which it is not, so I'll beat them to the punch:

Altima FWD
GXX RWD

I owned a 2003 G35 (first year) and everyone thought it was a badge-engineered FWD Altima or Maxima.

I really hope that these new CAFE standards don't cause people to go back to FWD for everything.

Repeat after me:
The front wheels are for steering only, the rear wheels are for power.

Sounds like an Acura TSX Competitor but with rear-wheel drive. You can bet they'll be cross-shopped if indeed it makes 210 horses.

well at least we know the figures mentioned above arent accurate. 280hp makes much more sense and would likely kill sales of the V6 car.

Not sure about the knock on the inline 6 above...sweetest motor on the planet. I've got a nice one in a 92SC300....Had many in different BMW's......

I'm thinkin' typo - maybe 310HP?

The idea of making a more economical G25 coupe is fantastic since it will appeal to a larger demographic of lower income and younger car buyers. However, the idea of making a 3,600 to 3,700 pound car sporty with a mere 210 hp will not be praised buy critics and consumers alike. Ultimately I think if the car performs well for the price that it will give consumers a better initiative to buy the G25 sedan. Good luck Infiniti.

Isn't the G fairly heavy? This might actually be slower than the IS250

This article has a HUGE error. The Nissan Skyline 250GT is normally aspirated.

The turbocharged VQ25DET makes 280HP/300LB.FT.

@umiami350:
Yes, this is the ACTUAL refreshened G sedan.

@mrjost55:
Even though the G sedan is heavier than the IS250; it will still have more power/tq and will be offered with a seven-speed auto. So it wil still be quicker than the IS250.

What has everybody been smoking? The N/A version of the 2.5 I4 in the Sentra Spec-V makes 200 hp and 180 lb-ft. The N/A version of the 2.5 V6 in thr Nissan G25 makes 210 hp and 195lb-ft while the Turbo version of the same engine is being estimated at 250+ hp. Now the new 3.0 I6 base engine in the upcoming 528i is going to be rated at 258 hp and i'm pretty sure its going in the new 328i as well.

@inlinesix

I figured as much as that was way too low for it. looks like they fixed the post not stating that it could make about 250HP.

As for those complaining about people buying it just for the nameplate, if you don't like it then buy the G37 instead. A G25 would be more than enough for 90% of the day-to-day driving most people do. the A4 2.0T replaces the 3.2 since it not only outsells it but also outperforms it.

The torque band will really be interesting to see how well it will perform vs the G37. wouldn't mind getting one if I was in the market and looking at a car like this.

Three cheers to Infiniti for offering a small V6 and not a 4-banger. I'm sorry, but 4-bangers are vulgar in luxury cars...

Wonder "Twin-Turbo" power...ACTIVATE!!

First off, I'm very disappointed at Insideline for making this goof. You guys can do so much better. Those are not the Specs of the VQ25DET at all! Come on guys, I know you can do better. Second of all, for those of us waiting for the return of Nissan's RWD coupe, this is just like Nissan to secretly tease you and introduce you to a potential engine for that car. Maybe to see how the consumers react to the engine. If not, its still fun to think about.

The car looks like a Toyota Yaris on steroids, which is not a compliment

i never post but omg..... about 4 people actually read the article. Inside Line did not goof anything up!
they are stating that the N/A version makes 210hp so the turbo will be likely around 250hp (I think it will be a bit higher)
Now i'm guessing the next post will be "210hp out of a Turbo 6?!?! pathetic!"

just wow.....

What liljonson said. Everybody, read the post again, slowly… maybe it could’ve been organized differently to prevent confusion, but it states quite clearly that the naturally aspirated 2.5L V6 gets 210hp – and that’s the engine which will be turbo’d.

Personally though, I think Infiniti should just offer the naturally aspirated 2.5L V6. Plenty of buyers are fine with just over 200hp, especially those who bought their current cars before horsepower numbers all went through the roof. Besides, how could a turbocharged small V6 be cheaper than a larger V6?

I think this is a move that makes sense and look forward to the G25's arrival, but it won't happen just so they can undercut the 328 in price. Expect the G37 to move up. Right now the G37 plays in both arenas and they know it so pricing is kept in line to split the difference. Aim the G25 at the 328 and wring more profit out of the G37 by pricing it closer to the 335. My 2 cents.

"Yeah, but the 3.0 liter BMW engine is very sweet to rev. I'd have a hard time choosing a turbo four with lower output."

Um... ITS A TURBO SIX. As many have already pointed out numerous times in the thread.

Also, smart move by infiniti. I can just see the showroom conversation. "Hey the BMW has less horsepower AND is more expensive, plus if you don't think 250hp is adequate enough, the tuners love these cars, so it's not like there isn't anything thing you can't do about that hint-hint."

ddark13 please read the article slowly, and you will see that you are the one who is PATHETIC!!. People, everything in the article is CORRECT! The 210 HP is the N/A engine in the entry level model that is sold in Japan (Skyline). Edmonds have not said how much HP they expect from this engine when it is turbo charged, but it is safe to expect close to 300 HP. People, please read before you all make a fool of yourselves

I have an 08 G35x. Lease is over in 18 months. The only thing I think can improve with this car is the gas mileage. I'll test drive this G25, if it doesn't seem like such a step down, ill buy it. If its not enough, Ill get the new 2011 M thats coming out. I just dont want to part with another lease disposition fee!

It is pretty sad when so called car enthusiasts (I'm talking about some of the readers here, not Edmunds) jump to conclusions without even reading or understanding the article. It clearly says that the new 2.5L V6 (6, not I4) which makes ~200hp in normally aspirated form (that's non turbocharged for the "enthusiasts" here) will come to the US in a G25 as a turbocharged 2.5L V6. My guess is that it will hit into at least the 250hp range so as to not upset the top line 327hp 3.7 V6 engine. Following the usual Infiniti trend, it will offer more HP than the corresponding BMW for less money.

This is just my speculation:

2011 G37: 3.7 direct injection with 350hp
2011 G25: 2.5 direct injection turbo with 300hp.

Wow some people who came in late are SO confused.

@ EVERYONE: The article was changed mid-day. It was wrong. Now its accurate.

Better now?

Can't wait to see the VQ25DET... =)

The VQ25DET is a turbocharged 2.5 L (2495 cc) engine with CVTC. Bore and stroke are 85 mm and 73.3 mm, with a compression ratio of 8.5:1. It produces 280 PS (210 kW; 280 hp) @6400 rpm and 300 ft·lbf (410 N·m) @3200 rpm

Great: Edmunds corrects their blog posting, and now my initial post appears nonsensical. Thanks for informing the latecomers, INLINESIX!

Now will this engine make it to the 370z or will the Silvia get it ? that is the question

Now will this engine make it to the 370z or the silvia? that is the question

That is a fantastic idea! They should have done this long ago. I always wanted them to drop the old 3.0 VQ into the car but this'll work nicely too.

Plus it will help lighten the car hopefully by a couple hundred lbs. The G37 is a nice enough car but man is it a tank. Dropping some weight from the nose will help this problem.

THIS IS WHAT THE ORIGINAL ARTICLE SAID:

"Inside Line has learned from an unnamed high-ranking source within Nissan that Infiniti will launch a turbocharged version of its popular G sedan in the fall of 2010. The entry-level model will be called the G25 and will use the same turbocharged 2.5-liter V6 Nissan uses in the Japan-market Skyline 250GT (The Infiniti G is sold in Japan as the Nissan Skyline.)

At launch, the smaller turbo engine will be in the G sedan only and be sold alongside the naturally aspirated V6-powered G37. The idea is that the lower entry price and improved fuel economy of the turbocharged engine will give Infiniti more head-on competition for the popular BMW 328i.

In Japan the turbocharged engine is rated at 210 horsepower and 195 pound-feet of torque, which is competitive with the 3.0-liter inline-6 in the BMW, which is rated at 230 hp and 200 lb-ft.

As of now, a G25 coupe and convertible are not planned, but if sales are brisk on the G25 sedan, both will happen."

EDMUNDS CHANGED IT MID-DAY.

jederino: me too :(

Haha, I was getting pretty annoyed at comments because it seemed like everyone had a complete inability to actually read and understand the article before commenting. It’s not really a big deal but I think they should make a footnote about the edit when a correction is made.

+1 Scotty

I think it will sell well, especially if the price is less. A lot of buyers like the G37, but don't care about all the power it makes, and are turned off by the crappy fuel economy it gets. They would rather trade off some acceleration for better fuel economy and a lower price.

I think this is brilliant. The boring out of the VQ 6 has led to great power and an impressive redline, but it's not quite the smooth engine it once was.

By going to a small displacement six, this thing will be a rev-hound. Turbocharging will increase it's efficiency and improve fuel economy while keeping power very respectable. And hopefully dropping a bit of weight.

The tuning scene will love it.

If they can manage to work some DI/variable turbine geometry/etc. magic into it, it'd be awesome to have a nice broad torque curve.

With this move, Toy-exus would no doubt answer back with a bump in power for their anemic IS250.

I think it'll do pretty well, even if they went with like a 2.3L turbo

most of the ISs I see on the road are the 250 versions, and occasionally I see the 350

so obviously most people don't care if the car is on the slow side (my RSX-S is faster than the IS250,sadly), they want the image that comes with the car.

and it also helps bring up their CAFE average cause now if someone wanted to drive a G but wanted something more economical, they have another option.

all-in-all, I'm interested in how this turns out. Just, it's kind of sad having a 5 year old FWD economy car be faster than a new RWD sports car

Why are people so obsessed with speed and acceleration times ? Especially in the US where the road system really doesn't encourage fun driving (except highway 1 which is CRAWLING with cops).

The article says they expect output to be around 250 bhp. The competition is clearly the lexus IS250, Audi A4 and 328i.

Currently the 328i sells way more than the 335i. There's no question that infiniti is leaving sales on the table without a smaller engine. Also - they ABSOLUTELY NEED this for the european markets (which they entered in a small way in 2009 and want to expand). A 3.7L engine gets taxed to hell in a lot of markets where registration tax is based on engine size.

@Joe, this turbo six sounds promising, but appears to have different bore and stroke from the orginal smooth VQ30DE. It must be a smaller and lighter block, but I hope it revs as sweet or better!

WHOA...most of you guys misread this article COMPLETELY wrong. I just re-read the article and it says that the normally-aspirated 2.5liter V-6 pumps out 195 pound feet of torque and 205 horsepower. Normally aspirated means...NO TURBOS or no forced-induction of any kind.

My guess is that it's probably gonna pump out the same 270HP from the base R34 Nissan Skyline GT-R (which the funny thing is, the same horsepower I have on my Nissan Altima V-6).

People...stop reading the articles TOO FAST and read them carefully!!!

^^Is Bruce kidding?

PLEASE PEOPLE READ, COME ON IT CLEARLY SAYS THE NUMBERS ARE FOR THE NORMAL ENGINE (NON TURBO) and they do NOT KNOW the numbers for the TURBO that they have been told is on the way.

I "mostly" AGREE WITH bruceleroy81 I predict 265hp, the reason the Altima V6 is at 270hp is that the transmission and cvc joints on the Altima are not quite as heavy and as those on the Maxima so they have detuned the Altima's 3.5 to make those parts more reliable so Nissan would not have to do a bunch of Warranty work, (at least thats my theory)

FROM ARTICLE ABOVE!!!!
"In Japan the normally-aspirated engine is rated at 210 horsepower and 195 pound-feet of torque, which is competitive with the 3.0-liter inline-6 in the BMW, which is rated at 230 hp and 200 lb-ft. We expect the turbocharged version to be closer to 250hp."
