MotorTrend reports that GM insiders are saying that the next-generation Cadillac Escalade will jump from its current GMT900 truck platform to the Lambda crossover architecture that underpins the GMC Acadia, Saturn Outlook, Buick Enclave, and Chevy Traverse. MT points to the Buick Enclave Super that didn't happen as evidence that an Escalambda would be able to handle an eight-cylinder engine, which would be a step up from the rest of El Generalissimo's increasingly-crowded crossover lineup. Edgier, CTS-like styling would likely be a given, too. Frankly, this is a good idea. The packaging afforded by the Lambda platform is vastly superior to what the GMT900 trucks offer. Remember that in the latter, the 3rd row is bolted to the cargo floor, it doesn't fold flat, and it's generally uncomfortable. The Lambda solves that instantly, and is better suited for what's positioned as a luxury vehicle anyway. Ride quality would be much better, and if GM Design were to deliver an interior on par with what's now found in the CTS, a Lambda-based Escalade would probably represent a quantum leap forward in terms of styling and refinement over the current vehicle. As for the Avalanche-based Escalade EXT, MT says that GM's mulling over the idea of moving to a unibody pickup, a la the Zeta-based GMC Denali XT concept, to replace both of those vehicles. Again, not a bad idea, especially for Cadillac. The downside is that owners of the current vehicles who use them to tow will likely need to look elsewhere to fill that need. Still, if Cadillac's gig is to sell legit luxury vehicles, moving to more car-like platforms makes all kinds of sense. It's going to be really interesting to see if any of this stuff actually pans out.
The current Buick Lucerne shares its underpinnings with both the Cadillac DTS and the Chevrolet Impala, but all three vehicles are set to go their separate ways when they're refreshed in a couple years. Last month we told you that the Impala was staying FWD, and now Motor Trend is reporting that the Lucerne could still receive RWD, but it won't be as big as the DTS/STS replacement. GM is looking into the feasibility of producing a smaller Lucerne that will ride on a wheelbase several inches shorter than the 118.5-inch spread slated for the future Caddy.
The move to shrink the Lucerne will have a lot to do with stricter CAFE standards in the years ahead. MT wisely points out the fact that the Pontiac G8, which already sits on a smaller Zeta platform, shows that RWD isn't always a fuel drain. The current Lucerne is pulled with the front wheels, and gets 16/25 with the ancient 3.8-liter V6 and 15/22 with the 4.6-liter Northstar, while the smaller G8 achieves 17/25 with the 3.6-liter unit and 15/25 from the tried and true 6.0-liter pushrod. Besides the smaller Zeta's fuel economy advantages, downsizing the Buick helps keep the Caddy exclusive over the more pedestrian Lucerne.
It has been rumored for the last few months that Chevrolet would be soldiering on with a front-wheel-drive Impala for at least the next few years. The recent contract agreement between the Canadian Auto Workers union and General Motors appears to cement this rumor as fact. According to the signed pact, GM promised to keep the Oshawa Assembly plant, where the current-generation Impala is made, open until 2012 -- two years longer than first planned. The Impala is a pretty good seller for the General, so we're not too surprised that upper-level management would want to leave it alone, but that doesn't stop us from wanting to see Chevy's bread-and-butter full-size sedan return to its roots by going rear-wheel-drive.
One thing is for certain: by the year 2012, the W-Body platform of the current Impala will be absolutely ancient. On the other hand, we've had nothing but good things to say about the new Zeta platform which underpins such enthusiast-friendly vehicles as the new Pontiac G8. Therefore, we can at least hold out some hope that GM will find a way to offer as many vehicles as possible using the new chassis architecture, whether they are named Impala or not. Anybody want to see a new Nova?
After our sampling of General Motors' rear-wheel-drive Zeta platform in the 2008 Pontiac G8 GT, we must admit that we're smitten with the platform. Its future in GM's North America car lineup, however, remains in question thanks to stricter CAFE standards that start going into effect by 2011. While the G8, G8 Sport Truck (actual name still pending) and Camaro are all guaranteed a spot on the Zeta platform, other vehicles like large RWD sedans for Chevy and Buick are likely dead in the water, according to Motor Trend. Hopes for a RWD Impala are all but gone thanks to strong sales of the current front-wheel-drive model, which continue despite the success of the now similarly sized Malibu.
Motor Trend also notes that GM plans to merge its current Sigma RWD platform with the Zeta around 2011. At that time, the Zeta/Sigma platform will be built in three sizes – coupe, midsize with 114.8-inch wheelbase and large with 118.5-inch wheelbase – and offer a premium version of each with forged aluminum suspension components. See the list below for a breakdown of how MT thinks things will look by 2011.
Zeta/Sigma variants:
Coupe – Camaro, maybe Holden Monaro and Pontiac G8 Coupe
Coupe Premium – Cadillac CTS Coupe
Midsize – Pontiac G8 and Holden Monaro, maybe Chevy sedan (not Impala)
Midsize Premium – Cadillac CTS Sedan
Large – Holden Statesmen/Buick Park Avenue (China), Holden Ute/Pontiac GT ST, maybe Buick Lucerne replacement
Large Premium – Cadillac STS/DTS replacement
Finally, MT also speculates that GM is working on a small rear-drive platform for Cadillac in Europe. The resulting 3-Series fighter would give Caddy more cachet in the old country, though MT does not specify is this would be an all-new platform or a larger variant of the Kappa platform that underpins the Pontiac Solstice and Saturn Sky.
Spot any similarities? Holden surprised and delighted when it rolled out the Coupe 60 at the Melbourne Auto Show this past week. Motor Trend put two and two together and dug up some three-year-old photos that show off essentially the same car wearing a Pontiac suit, instead. The nose on the original concept shows what GM was planning for the next-gen GTO at the time. We're glad the prototype styling was deemed too expensive for production; the world wasn't ready for a modern interpretation of the 1982 J2000.
The Coupe 60 started life as Pontiac's replacement for the sales-proof GTO, but Motor Trend reports that development stopped when GM went full bore at getting its next-gen full-size GMT900 trucks to market early. The reappropriation of this past work to create the stunning new Holden show car could signal a return of the Monaro, which could trickle down to North America as another page in the G8 brochure, or a new GTO, but don't start holding your breath yet.
Prior to his keynote speech at the Consumer Electronics Show in Las Vegas yesterday, GM Chairman Rick Wagoner held a discussion with a group of us flacks to answer all of our questions clearly and completely without equivocation. OK just kidding, he did hedge on a number of questions as would be expected of any major executive, especially one heading up the largest automaker in the world (for now). A range of issues were discussed, including alternative fuels, hybrids and the fate of the Zeta platform beyond the Pontiac G8 and the Camaro. Wagoner reiterated that nothing had changed on the status of the Volt and that it was still on track. He expressed appreciation that the EPA had denied the California waiver request for its greenhouse gas rules so that carmakers could focus on meeting one national set of CAFE standards. Also related to fuel economy, he declined to comment on the status of some vehicles planned off of the Zeta platform, aside from the fact that they were still considering options including models with smaller engines.
GM's Australian subsidiary Holden has recalled 86,000 rear-wheel-drive Zeta cars with the V6 engine to correct a potential fuel leak that could lead to fires. The CNN Money article says that the recall doesn't impact the Pontiac G8, GM's North American Zeta variant, because that car's underhood layout is different. We should also mention that the G8 is not even on sale yet, so there are none in customer hands to recall.
