We got word from a little birdie last week that Noble had flown over a prototype of its newest model – the M600 – for a series of shakedowns in the western U.S. CAR was able to get a shooter out to Arizona to capture the M600 undergoing testing, using the same Yamaha-developed V8 found in the Volvo XC90. According to CAR's sources, the V8 has been fitted with twin turbochargers and output is estimated at somewhere north of 600 hp. The rationale behind using the Volvo's lightweight eight is primarily centered on emissions, allowing the low-volume automaker to sell the M600 throughout the world.
"We're ready. When (customers) want it (the option of smaller engines) - we'll do it." That's a (somewhat mangled) quote from Thomas G. Stephens, GM's executive veep for global powertrain and quality, speaking at the inauguration of the General's Powertrain Engineering Development Center last Friday. What Stephens is referring to is the possibility of equipping Cadillacs with smaller, turbocharged engines – specifically fitting the 260-hp (or more) 2.0-liter, turbocharged four in the CTS sedan.
Sounds like a Hell of an idea, but how – exactly – is GM going to determine when consumers are ready for it? How about now?
Prices at the pump may have peaked (for now), but consumers are still craving fuel-efficient rides that don't skimp on power and poise. GM is already making V8 levels of output with its direct-injected 3.6-liter V6 (see: Camaro) and that, coupled with Stephens' quote, means that GM isn't totally oblivious to the idea of offering smaller engines that balance fuel economy and thrust in packages that might benefit from them. But again, how will the market tell GM when it's open to the idea of fewer cylinders making just as much power? Ford is already ramping up to release its line of direct injected, turbocharged EcoBoost engines, BMW has proven that turbocharged sixes are the bee's knees and practically every other automaker is looking into forced induction as a means to a lighter, more powerful, more fuel efficient end. So why is GM stalling? If the General has the capabilities, it needs to step up and let the market embrace it. It will. If GM doesn't, it risks its own extinction.
When it comes to increasing fuel economy, turbochargers are the replacement for displacement. The combination of highly efficient snails and smaller engines provides the power people expect, while reducing the overall weight of the vehicle. Like other automakers that have realized that forced induction is a suitable stop-gap for improving fuel economy, Mercedes-Benz is in the process of developing turbo'd engines that will proliferate throughout its lineup in the next two and a half years.
Thomas Weber, a Daimler board member in charge of research and development told Automotive News, "All our vehicles will have turbocharged engines in series production by the end of 2010 at the latest."
Mercedes is joining BMW and Audi by investing heavily into forced induction, primarily to cope with new fuel economy standards in the U.S. and Europe. But turbos are only going to take them so far. Mercedes plans to introduce hybrids into its lineup towards the close of the decade, beginning with the S-class sedan in 2009. According to Weber, zero-emission vehicles are the automaker's long-term goal and Daimler intends to push heavily towards fuel-cells and electric-powered vehicle in the future, including an electric smart fortwo which will go into production sometime in 2010.
According to sources speaking with Pickuptrucks.com, Ford is considering offering an EcoBoost four-cylinder engine on its F-150 pickup in 2013. The boosted mill is expected to displace around 2.5-liters, produce 260 hp and 300 lb.-ft. of torque, and would only be available on the two-door Regular Cab F-150 4x2 and 4x4.
Ford's rationale for equipping its workaday pickup with a turbo'd four is partially due to the rising cost of gasoline, but is primarily fueled by new CAFE regulations that will require light trucks to average 28.6 mpg by 2015. Ford has already decided to drop its 4.2-liter V6 for the 2009 model year, only offering the 4.6-liter V8, which produces more power and more torque, while still offering similar fuel economy.
The EcoBoost range of engines are likely to find their way into several different models across Ford's line up, and according to Ford's director of powertrain research, Dan Kapp, EcoBoost engines could allow the automaker to reduce engine sizes by between 40- and 50-percent, so 3.0-liter V6s could be replaced by two-liter fours and a 2.5-liter four cylinder could be reduced to 1.5-liters.
Before the EcoBoost four-pot debuts on the 2013 F-150, Ford will launch a turbocharged V6 in the pickup in 2010. Displacement is expected to be around 3.5-liters, with output estimated at around 350 hp and 390 lb.-ft. of torque. Partnered with a new six-speed transmission, fuel economy should be around 16 mpg city and 22 mpg highway.
And what of the rumored F-100 pick-up? It's conceivable that the range-topping version of the compact truck could be packing the same turbo'd four as its big brother, while a naturally aspirated version would power the entry level model.
BMW may begin straying from its long held tradition of equipping its M models with rev-happy, naturally aspirated engines. According to a source speaking with Automotive News, the twin-turbocharged 4.4-liter V8 currently equipped on the new X6, could be stroked out to 4.8-liters and fitted on future Ms, including the new M5, due out in 2011. The twin-turbo'd 3.0-liter inline six found in the 335i, 535i and entry-level X6 proved that BMW has the chops to create highly efficient and eminently entertaining blown mills, and there's no doubt that significant tweaks to the turbocharged V8 could boost power levels over the stock mill's claimed 407 hp, to take take serious aim at Audi's 572 hp RS6.
BMW has continued to deny the existence of an M-version of the X5, and by all accounts, it's true. The blokes from Bavaria maintain that the 'ute's size, weight, height and packaging won't warrant the tri-tones of the vaunted M. But the doesn't mean BMW can't produce a hotter version of its biggie-sized SUV.
Using the same 407 hp, 4.4-liter twin-turbocharged V8 found in the recently released X6, BMW is taking aim at the Porsche Cayenne Turbo. KGP was able to snap off a handful of shots of the turbo'd X5 running the 'Ring, and despite the lack of a factory-approved M on the hatch, it's looking decidedly more aggressive than its siblings. The front fascia is taking all the normal cues from BMW's motorsports department, with massive air intakes and a gaping central air dam, while a set of quad exhausts are framed within a new rear bumper. There's no word on when the hotter X5 will debut, but with the Paris Motor Show right around the corner, BMW surely has a few things up its sleeves.
Two separate reports out of Australia say that Holden is looking to maximize the Commodore's fuel efficiency in an effort to stoke sales. Both stories quote General Motor's Asia-Pacific vice president, Nick Reilly, but the separate reports, while sharing a common theme, come to decidedly different conclusions about how the General plans to proceed.
The first story from the Sydney Morning Herald (thanks Patrick!) cites Reilly as saying that Holden is looking into hybrid technology to power the Commodore. "[It] could be one of the first hybrids that you will see," but Reilly insists that a gasoline-electric Commodore is still a few years out.
The second report comes courtesy of Drive.com.au, who also spoke with Reilly and asked if a four-cylinder version of the Commodore was in the cards. "It makes a lot of sense," Reilly said, "and therefore we're probably looking at it, but I can't tell you when." While that's far from a confirmation that a turbocharged four is on the way, it coincides with earlier reports that the new Camaro, which shares its platform with the Commodore, might benefit from the same 260 hp, turbocharged 2.0-liter found in the Pontiac Solstice GXP and Saturn Sky Redline.
Both stories are somewhat devoid of hard details, but despite that, it may be proof that General Motors' operations Down Under are willing to look at a variety of solutions to address the Commodore's slipping sales.
General Motors' European division has announced the development of three new engines that will provide the power consumers crave while returning higher fuel economy and lower emissions. Two turbocharged engines, ranging in output from 1.0- to 1.4-liters will between 120 hp and 129 lb.-ft. of torque, and 140 hp and 148 lb.-ft. of torque, while returning an eight-percent increase in fuel efficiency compared to their larger displacement counterparts. The duo of new engines will find their way into the new Astra and some European-market Chevys in 2010, although there's no word if either engine will make the trek across the Atlantic.
Emerging reports suggest that the next Audi S4 will ditch the current model's V8 and open up the gap a little with the top-of-the-line RS4 with a new supercharged V6. Bearing the 3.0T or TFSI badge, the 2010 S4 could benefit from "twin-charging" with the possible inclusion of a turbo in addition to the supercharger.
With a potential unveiling at the LA Auto Show in November, the supercharged S4 is also tipped to feature a Magna-sourced "sport differential" like the ZF unit featured in the BMW X6, bringing the fight to the turbocharged BMW 335i, while the RS4 takes on the M3. While power will likely remain similar to the current 339-hp 4.2-liter V8 and weight only marginally reduced by 100 lbs or less, the purpose in switching to forced induction would be to improve fuel economy while returning comparable performance. The S4 is also expected to be developed outside Quattro GmbH, while the RS4 would be created by the Audi performance division, giving the former a more restrained look compared to the all-out bulging bodywork of the latter. The forced-induction V6 is also tipped to replace the 3.2-liter V6 in the base Audi A6 Quattro.
JL sent us over an email from Subaru of America that's instructed dealers to immediate cease sales of all Subaru models equipped with the turbocharged, 2.5-liter four-cylinder engine. The directive effects some 2008 and 2009 models built in January and February, including the Forester, Legacy 2.5GT, LTD, 2.5GTB and Impreza sedan and wagon.
The issue involves reports of an "engine knocking noise" that's been affecting vehicles outside the U.S. market, and an initial investigation has found that there is some kind of internal wear that may be causing the noise.
Currently, no U.S. vehicles have been affected, and a Subaru spokesperson told us that the stop sale has been issued as a temporary measure to nip it in the proverbial bud and that once the issue is addressed sales will begin again. You can read the full directive and see the exact production dates of the affected models after the jump.
