its not that fast. http://www.leftlanenews.com/chevy-re...08-hhr-ss.html

I told ya.

The LNF is actually putting close to the same numbers to the wheels as the LSJ. It's just rated "correctly" (unlike the LSJ being way under-rated). 15% Drivetrane loss from 260hp flywheel leaves you with 221 at the wheels. I've seen stock SS/SC's dyno at 220 to the wheels.

I don't understand why everyone things the LNF is so superior.

And it's boosting what... 18PSI stock? Not too much room for improvement there.

Magazine race much???

The LNF dynoed 228whp and over 240 torque on the Solstice gxp/redline, RWD and FWD drivetrain losses are similar so you can probably expect the same number for the HHR. Now i dont know about weight and since its FWD it wont be as fast as the GXP/redline but it's still a good choice and I wish it was in our cars.

As well the LNF runs around 20 PSI, while that is alot the last gen evo ran 20 PSI and your gonna tell me theres no room for improvement with the evo? The LNF is a better starting point becuase of direct injection, VVT and turbo setup already. Swapping out for a better turbo would be easy and probably net good gains for less money than what you would need for the LSJ.

mph says it all.

Does anyone else NOT realize that the HHR SS is a good 300-400lbs HEAVIER than the SS/SC???? That alone will make a HUGE difference.

Jmc007

PSI means nothing if it's not combined with CFM. So yes there is room for improvement on that car cause the head and exhaust are surely not optimised for high HP numbers. Look at Hahn's stages on 2.4L Solstcice :

its nice...but its excatly like the ss/sc....shifter, boost gauge....the seats are hot...why didnt they just do a 2008 ss turbo charged...looks like a turbocharged hurst

oversight. just gut the car of crap you don't need (back seat, spare time, some trim, driver weight loss mod) lighter rims.

blktrax

They need to sell it in the Panel version.

Onyxd04Redline

Yeah. Gut a brand new car. Best idea i have ever heard.

Sanat

I'm sorry but that car is ugly as he11. so yeah. I wouldn't even bother comparing it to an SS/SC like some are doing.

BACK2GM

I agree 100%

Johnboy12358

I like the cluster, other than that, meh. I dont get the whole hatch back thing, coupes are far more sporty, and light....
I'm sure that engine would be fun in our cars though, its a shame they scrapped the cobalt SS instead of the HHR SS

halfj99

those wheels will fit your balts

What is the new 2008 Chevrolet SS?

The SS is a new addition to the HHR passenger model lineup. It combines all the style and capability of the HHR family with uncompromising performance, including a turbo charged and intercooled Ecotec 2.0L engine that produces 260 horsepower. The SS also features unique interior & exterior styling.

What makes this an SS model?

The 2008 HHR SS was engineered by GM Performance Division and is the first Chevrolet model since the Performance Division was charged with overseeing all the "go, stop & turn" requirements demanded by any new vehicle that wears the SS badge.

How does it drive & handle?

The HHR SS was engineered to offer more than simply increased power. An all new FE5 Sport suspension was developed and tuned at Germany’s famed Nurburgring racing circuit. This suspension includes specific stabilizer bar, special gas charged struts with unique spring rates & damper tuning. Consequently the HHR SS delivers a Corvette-like lateral grip of 0.90 g. The brake system is enhanced too with four wheel ABS disc system & Stabilitrak electronically controlled stability control system. All standard! Steering is tuned to match the SS’s handling. The electric assisted rack & pinion system has a quick 14.8:1 ratio, which is 30% quicker than other HHR models.

Is it fast?

Yes. Over 150 mph fast! This HHR SS is so fast, it just broke the class world record at the Nurburgring in Germany.

Can I get the HHR SS with an automatic transmission?

Yes. You can order the SS with an available 4 speed automatic transmission, which includes remote start. The base transmission is the high performance, short throw Getrag 5 speed manual.

Does the HHR SS have any unique exterior features?

Yes. New front fascia with fog lamps, to mesh-style upper & lower grilles, new rear fascia, rear spoiler, new rocker moldings, Special SS badges, 18" aluminum wheels/tires, body color door handles, body color mirror caps & body color license plate surround.

What about the interior? Is it different as well?

Like the exterior, the interior is unique to the HHR SS, including SS embroidered sport seats with suede-like inserts (think Recaro seats only better), special gauge cluster, pillar mounted turbo boost gauge, special short throw shifter, door panel mounted window & door lock switches & special floor console that actually wraps around the shifter.

I hear the HHR SS has a "no lift shift" feature when equipped with the manual transmission. What is that?

"No lift shift" allows the driver to shift the manual transmission without taking your foot of the accelerator. This segment exclusive feature allows for the lighting fast six second 0-60 time.

Can I get OnStar & XM Satellite Radio in the SS?

Yes, it’s standard.

What are the fuel economy ratings for the HHR SS?

You get 260 horsepower & 27 mpg on the highway. That’s a 432 mile range!

When was the HHR SS revealed to the public?

On August 16, 2007, Bob Lutz revealed the HHR SS at the Woodward Dream Cruise.

When will the HHR SS ordering process start?

Orders for the HHR SS will be accepted late October 2007. The first DOSP is scheduled for mid November.

What is the model code for the SS?

1AU46.

When will vehicles begin to arrive at the dealerships?

The HHR SS is scheduled to begin production December 2007 and will begin arriving in Dealerships in late January 2007.

What is the competitive set for the HHR SS?

The HHR SS is unique to the class since Chrysler PT Cruiser announced the cancellation of their GT during 2008. However, the Dodge Caliber, regular Chrysler PT Cruiser, Dodge Nitro and Scion xB are the competitive set.

Is there preliminary pricing for the 2008 HHR SS?

Pricing is not available at this time, but we are estimating a starting price around $25,000.

What are the production estimates for the HHR SS?

The initial production forecast is for 10,000 units annually, although there is the capability to increase production.

How can I get more information on the 2008 HHR SS?

The HHR SS is featured in the 2008 HHR catalog which is currently in Dealerships now. We also have hero cards that be ordered through Dealer World. Stay tuned to chevylaunch.com, chevrolet.com, chevynation.com & hhrclub.org for even more information & updates.

GM still hasn't gotten rid of that horrible 1st gear yet. Moron's.

Area47

factory power shift option.

hmmmmmm

g5mike

that "no lift shift" sounds awsome!!!

SilverSS/SC

Thank you for some reality

Cobalt - in the 1/4 anyways .....it will ET faster than the S/C car , but the mph should remain close to the same . In reality the LNF is about a 10 hp gain from actual LSJ hp . The LNF murders it when TQ is concerned though , pumping a hell of alot more TQ from 2000 rpms on up to about 53-5500 , the same cannot be said about the LSJ . The Torque on my dyno sheets from stock really doesnt start to shine until 4500 rpms .

I beg to differ . That tiny turbo will face the same issues as the M62 on the LSJ . Compare 21 psi thru the M62 and the same 21 psi thru say ..a 20g . Not sure of the compressor Mase had on his , but the difference was about 120 hp . Boost levels can be very decieving , if thats your sole basis for determaing the output of any given engine .
