Hennessey Cadillac Escalade gets 557 hp

The 2015 Cadillac Escalade is about as American as an SUV can be. We didn't find the 420-hp, 6.2-liter V8 lacking in any way, but if you want something with a little more grunt, Hennessey Performance Engineering and its HPE550 upgrade should help. Hennessey says the HPE550 Escalade package bumps output to 557 hp and 542 lb-ft of torque with the help of a belt-driven supercharger producing 6 psi.

Toyota recalls Lexus cars for fuel-system fixes

Toyota Motor Corp., struggling to restore its reputation for top quality, on Wednesday recalled nearly 1.7 million vehicles globally for a variety of fuel system related problems, including 245,000 Lexus IS and Lexus GS sedans in the United States. The North American vehicles are being called back to inspect for possibly faulty installation of fuel pressure sensors. In cases where the sensor is not fastened tightly enough, fuel can leak between the gasket that connects the sensor to the fuel delivery pipes, Toyota said.

Muscle-car icons immortalized in new postal-stamp set

Perhaps sensing that it's at risk of going the way of the carbureted big-block and leaded gasoline, the United States Postal Service is apparently willing to try anything to boost its bottom line. Though we're sure its recently announced line of postal worker-inspired apparel will be a runaway (and runway) success, we're glad to see the USPS reaching out to the automotive-enthusiast community with a new set of limited-edition stamps that commemorate the American muscle car. We told you about the stamps earlier this year, but we can now confirm the lineup.
