The Corvette Blogger via Jalopnik reports some independent chassis dyno results for the new 2009 Corvette ZR1 supercar. Now the LS9 supercharged 6.2L V8 in the Corvette ZR1 is not identical to the LSA 6.2L supercharged V8 in the new CTS-V. The one in the Corvette is hand built and hardened a bit compared with the more production engine in the CTS-V. The Corvette makes 638hp, the CTS-V 556hp. The Corvette has a larger supercharger at 2.3L vs 1.9L for the Cadillac. But it is interesting to see how the Corvette engine performs none the less as a ruler for where we might see the CTS-V perform.
Results? The average chassis dyno was 548hp. With tuning the shop was able to get them up to around 567hp. At 15% transmission/drivetrain loss, the 548hp matches up well enough with the claimed 638hp of output at the crankshaft. Put another way, 548hp represents 14% drivetrain loss which is in the expected range.
Hopefully we will see the CTS-V manuals put up similar numbers, hitting around 475hp on the chassis dyno.
Autoblog has a post with a photo gallery of the 2010 Cadillac CTS Sport Wagon.
I keep saying Sport Wagon but sometimes it is shown as the plural Sports Wagon. I’ll work on it. GM messaging looks like it always shows it singluar. Anyway, good that the ‘general’ car blogs are picking up on the new CTS Sport Wagon.
Meanwhile Jalopnik is running info on the Chevrolet Volt. GM showed the Volt live this morning as part of GMNext.com day and the 100th birthday celebration. The Volt is more and more interesting if the powerplant may next migrate to a future Cadillac model.
The dramatically-designed 2010 Cadillac CTS Sport Wagon makes its European premiere at Paris, followed by production launch in spring of 2009.
GM is noting that the Volt is NOT a plug-in hybrid, but rather an extended range vehicle. Ah; I’ll have to think about that, but I think they are pointing out the difference between a hybrid with minimal battery backup like the Toyota Prius or the 2-mode Cadillac Escalade Hybrid, and a car like the Chevrolet Volt that actually is an electric car with a gas engine generator to recharge on the go.
Top speed of 100mph may be new news, but seems plenty fast enough for most people.
