http://www.autoblog.com/2007/10/28/officially-official-2008-chevy-cobalt-ss-bows-at-sema/This is the turbocharged 2008 Chevy Cobalt SS, and it's being introduced to the world at SEMA this week. Chevy went to great lengths to ensure that the SS badge means more than what it had become in recent years.
Coming in at 260 HP / 260 lb-ft, the SS/TC gains a full 55 horses over the now-defunct SS/SC. Power, of course, is sourced from the same 2.0L direct-injected, turbocharged, intercooled sledgehammer found under the bonnets of the Pontiac Solstice GXP, Saturn Sky Red Line, and forthcoming Chevy HHR SS. The GM Performance Division was tasked with making sure the improved Cobalt SS is well-sorted, and John Heinricy and company dialed in the FE5 sport suspension on the undulating twists and turns of the Nürburgring Nordschleife. The result, says GM, is a track-capable suspension that's still comfortable on the street, and which helps mitigate FWD performance foibles like torque steer.
The standard transmission is the GM Powertrain Sweden F35 short-throw 5-speed manual with a "no-lift shift" feature. This, combined with the punchy turbo four, helps propel the Cobalt SS Turbocharged from 0 to 60 in a scant 5.7 seconds. In fact, GM set a Nürburgring class record for FWD sport compacts with the turbo Cobalt, lapping the Green Hell in 8:22.85. Better braking accompanies the added power with 4-piston fixed-caliper Brembos in front and vented discs with single-piston calipers in the rear. A driver-selectable competition mode with launch control can be enabled from the ****pit. Beyond that, the traction control system can be completely disabled.

http://www.autoblog.com/2007/11/01/rumor-mill-corvette-c6rs-might-go-into-limited-production/We just got a tip from a knowledgeable source that Pratt & Miller have all but acknowledged that Jay Leno's wild Corvette C6RS will go into limited production. We hear that 25 will be built at a cost of $185,000 plus a donor car. Although the Katech motor in the C6RS is a bit larger than the one in the Pratt & Miller Street Attack model, the E85 hook keeps power the same at 600 HP. Not a lot of other details are available yet, but we wanted to make sure we shared. We'll keep you posted when more info gets released.

UPDATED DOORThe Boss engine is a forthcoming all new large-displacement V8 engine project at Ford Motor Company. The engine project was reportedly canceled in 2005 as the company focused on its existing Modular V8 and V10, but was reportedly revived in early 2006 by Mark Fields.  The large engine will compete with DaimlerChrysler's 6.1 L and larger Hemi and General Motors' 6.2 L Vortec engines. The Boss V8 will be built at Cleveland Engine in Cleveland, Ohio and the first application will be Ford's new 2009 (likely a late availability 2009 or 2010 model year option) F-Series pickup trucks produced at Dearborn Truck.
The Boss engine will reportedly displace 6.2 L (6207 cc/379 in³) and produce roughly 425 hp (317 kW) and 425 ft·lbf (576 N·m) upon introduction. The engine architecture will offer the ability to exceed 7.0 L in future applications. Insider reports indicate the Boss will retain several design similarities with the Modular V8 such as deep skirt block with cross bolted main caps, crankshaft driven gerotor oil pump, and overhead camshaft valve train arrangement. The Boss' single most significant departure from the Modular V8 will be the seen in the significantly wider 4.53 in (115 mm) bore centerline (The Modular V8 is 3.94 in (100 mm) by comparison). The 6.2 L will reportedly employ a 4.015 in (102 mm) bore diameter and a 3.74 in (95 mm) stroke to achieve it's 6.2 L of displacement. The initial versions of the Boss will have single overhead camshafts, two valves per cylinder, two spark plugs per cylinder and employ a form of cylinder deactivation for increased fuel economy. Initial information on valve sizes of the 6.2 L puts the intake valve at 2.10 in and the exhaust valve at 1.65 in.  Later high-performance versions will be equipped with DOHC 4-valve heads and Gasoline direct injection (GDI). A "TwinForce" 6.2 L DOHC 4-valve, twin-turbo, GDI version of the Boss is currently being developed and has reportedly produced over 650 ft·lbf (881 N·m) in initial testing.
Roush Racing is currently field testing an experimental, large displacement version of the Boss engine code named "777", which stands for 7.0 L, 700 hp @ 7,000 rpm, at National Mustang Racers Association (NMRA) events around the United States. The 777 Boss is naturally aspirated and runs on E85 biofuel.
The engine was initially called the "Hurricane", but this was changed in mid 2006 to the storied Boss name in the wake of Hurricane Katrina. 
General Motors is preparing to launch the Pontiac G8 and has announced pricing for the highly-anticipated sedan. Based on the Commodore from GM's Holden subsidiary in Australia, the G8 will serve as a replacement to the aging Grand Prix.
The base model — priced from $27,595 — features a 261 horsepower 3.6-liter V6 with 250 pound-feet of torque. A more powerful G8 GT — starting at $29,995 — delivers 362 horsepower and 391 pound-feet of torque thanks to a 6.0-liter V8.
The lone transmission option for both the V6 and V8 2008 models will be a six-speed automatic with paddle shifters. Earlier press information indicated that a manual option for GT cars would be available, but this is not the case. "What we've said — and which is still the case — is that the six-speed manual won't be available at launch," a Pontiac spokesman told Edmunds. "There is no manual option for 2008." It is believed that there will be a manual option for 2009, although GM has yet to confirm if and when a manual will be available.
Curb weight for the V6 model is 3,885 lbs, while the GT weighs just five pounds shy of 4,000. 18-inch wheels come standard, while 19-inch alloys can be ordered with the GT model.
The sedan rides on GM's new Zeta rear-wheel-drive platform, which underpins the 2009 Camaro and possibly the next-generation Impala, in addition to several other planned vehicles.
G8 deliveries are expected to begin in early 2008 — a relatively short lead time made possible by some very effective badge engineering.
