NEWS: Buick Lucerne Super gets 292hp Northstar from Deville Performance Sedan

NEW YORK – GM’s global product development efforts will converge in one city as the new 2008 Cadillac STS; two Buick performance models and a refreshed Buick LaCrosse sedan; more powerful versions of the HUMMER H2 and H3; and a first-ever Saab E100 bioethanol concept come to the New York International Auto Show, April 6-15 at the Jacob Javits Convention Center .

The introductions continue GM’s ongoing product blitz that began the auto show season last November in Los Angeles . Here’s a preview of what GM will show in New York :

Cadillac – The 2008 Cadillac STS features refreshed signature styling inside and out; a new, standard 298-horsepower (222kW) direct-injection V-6 engine; and new performance and safety technologies. They include StabiliTrak with enhanced variable effort steering, as well as a new lane departure warning system and side blind zone alerts. Coming to Cadillac dealers this summer, the 2008 STS extends Cadillac’s heritage of combining luxury, performance and technology.

Buick – Two new performance-enhancing versions of the 2008 LaCrosse and Lucerne sedans evoke a time-honored badge – the Super – that will make fast friends with those who demand a premium performer with elevated design to match. The LaCrosse Super gets a 300-horsepower (224 kW) 5.3L small-block V-8 with Active Fuel Management and, for the first time, Buick’s iconic portholes. The Lucerne Super adds a more powerful version of the legendary 4.6L Northstar V-6, for 292 horsepower (218 kW), as well as specific Super design cues.

The Super badge debuted in the 1940 model year and symbolized Buick luxury, power and performance for 18 years. With the 2008 La Crosse and Lucerne Supers, Buick is taking a great name from its heritage to designate the most premium cars it has ever offered.

In addition, all 2008 LaCrosse models get a new front end inspired by the acclaimed Velite concept car, as well as an enhanced list of standard equipment.

HUMMER – A more powerful, yet more fuel-efficient 2008 HUMMER H2 also features a redesigned interior that complements the vehicle’s legendary ruggedness with refinement. New standard safety features include roof rail curtain air bags.

The HUMMER H3 Alpha also debuts; it is the second member of the brand’s Alpha performance series. With a 295-horsepower (220 kW) V-8 engine and HUMMER’s trademark off-road capability, the H3 Alpha is top dog – on the trails or the turnpike.

Saab – Fresh from its world debut at the Geneva Auto Show, the Saab BioPower 100 Concept showcases the first production-based turbo engine to be optimized for pure, eco-friendly bioethanol (E100) fuel. Demonstrating GM’s leadership in biofuels and bioethanol technology, the 300-horsepower concept features unprecedented performance to match its greatly reduced CO 2 footprint. The production Saab 9-5 BioPower already is Europe ’s top-selling bioethanol (E85)-powered car.

GM Fleet and Commercial Operations – GM will help celebrate the 100 th birthday of the taxi cab in New York City by placing into the city’s taxi service the only vans approved to transport individuals with mobility-related disabilities or spinal cord injuries. The Chevrolet Uplander TC (Taxi Cab) features a lowered floor instead of a raised roof, providing easier passenger entry and exit as well as enhanced vehicle stability.

GM also will feature several concepts and production vehicles in New York that already have created buzz during the auto show season. They include the second-generation 2008 Cadillac CTS; the 2008 Saturn Vue and 2008 Saturn Astra; the Chevrolet Camaro convertible and Chevrolet Volt concepts, as well as the 2008 Chevrolet Malibu; and the 2008 Pontiac G8, and 2008 Pontiac G6 GXP and Torrent GXP models.

The new STS looks better. More rounded and proportionate.

GM needs to get on the stick with the FWD Northstar program. 292 is all they can offer. The new STS V-6 will offer more power. Just about every performance luxury V-8 has surpassed the Northstar now, in terms of power and torque, if not economy. Approaching 300 horsepower is no longer sufficient. GM needs to get the Northstar (or their new Ultra V-8 or whatever its called) into the 340-350 hp range using a similar displacement.

I am still betting the UltraV8 will be 380+hp, but we needed it for 2008. Two more years of development and some V6's will be hitting 350hp. Sounds like the 3.6L DI engine is going to hit the low end of the expected hp range, at 298hp. Compare to the 08 Infiniti 3.7L V6 at 330hp/270ft-lbs and Cadillac stays behind.

On the bright side, all of the current engine choices result in cars that move very well. The current STS V8 will do 0-60 in under 6 seconds; the new STS V6 with 298hp maybe 6.5s. The new CTS DI3.6L should be under 6 sec.

I'm about ready for a 300 horse V6 seeing my 01 STS is getting 11 to 12 mpg.

It shouldn't be. At that fuel consumption rate, something is wrong.

Mine gets the same thing. There is nothing wrong, that's just how the STS's are. Like mentioned in a different post, the only way to get really good is to drive like a grandma.

Peter1972,

What do you get on the highway? If you get low on the highway, then I'd be a little curious.

So what is the new 3.6 supposed to get for fuel economy if you drive it halfways decent?

I drive to redline at least 4-5 times each trip and average 19-20 in town, in my STS. My SLS was closer to 20-22. I'd be disappointed with 12 mpg in a Suburban, much less a Seville. You can drive smooth and still more than keep up with traffic.

Not in Minot you can't! :blink: It's impossible to get good mileage here. This is what most of you would consider a small town, it's only 40,000 people and there is pretty much one road to take to get to everything and there is a light every couple of blocks. The people here don't know how to time them so a person usually hits them all red. Everyone in this town drives like they are being chased by zombies. As soon as the light turns green, everybody floors it and if you aren't along with them, you will piss everybody off. Another thing is that it's always less than a mile to get where you want so it's always start stop, start stop. It's always being shut off and restarted, that doesn't help with mileage. You're probably getting that mileage with a little bit of freeway driving or at least some steady speeds. As soon as I get up to a steady speed I have to put on the breaks again and start all over. It's not a fun town to drive in. I guess the mileage is bad on the car because my suburban usually gets 10-11 and it's a 3/4 ton with the 6.0. I've done everything that I could possibly do to it, so I've learned to live with it. I mean, it is a cadillac, they're still fun to drive! I used to get 14, maybe 15, in the summer with my 95 SLS.

I used to live in Fargo, ND where it's all flat and everything is much more spread out and I could get awesome mileage there and it was all "in-town." Mileage really depends on where you're going, how far you're going, how fast you're going, and how you get there. I'm sure if I drove to work clear across town and took back roads, I could probably get pretty good mileage, but most of mine are short trips.

Yes, it sounds like your town is a bear. It's not what I'd consider "normal". With few exceptions (maybe yours included), I'd consider 12 mpg out of an STS too low. But you're right -- it all depends on where you drive.

I'm going to take different routes on this next tank and drive like I usually do and see what happens.
