#Turbo

Figuratively as well as literally, Bob Lutz’s work at GM is now done. Shortly before the towers fell (it seems so long ago) Rick Wagoner answered many an auto journalist’s prayers by recruiting the living legend to dramatically improve the company’s product development process and the cars it yields. In retiring (not for the first time, but probably for the last time), Lutz has declared this mission accomplished, with GM’s latest cars as proof. The Cadillac SRX 2.8 turbo is the most expensive—and so least cost-constrained—of these new cars. What does it tell us about what Lutz was able to accomplish, and about what work remains?

Taut. Trim. Modern. Sporty. Developed in Germany. Aimed at youthful enthusiasts. Stop me when it starts sounding like I’m describing a Buick.

The fastest car I have ever driven is, without a doubt, the Switzer P800 variant of Porsche’s 911 GT2, as reviewed here. The folks at TPC have a roughly similar tuning package that retains the Porsche variable-geometry turbochargers, claimed to produce 775 horsepower and rather amusingly called the “775 Blitzkrieg”. This past September, I had the opportunity to take a ride with TPC’s founder Mike Levitas in the prototype Blitzkrieg. It’s awfully quick, if perhaps not quite as violently impressive as Switzer’s car. However, since TPC was unwilling to let us drive the Blitzkrieg, and since TTAC is unwilling to follow the lead of EVO, Top Gear, and pretty much every other print rag in the free world by writing-up a ride-along as a road test, that’s where we have to let the matter rest. It seems like a good car and if you have money to burn, give TPC a call to find out for yourself.

The vocabulary used to classify hybrid drivetrains has been lagging considerably behind new developments, as Wikipedia’s article on the matter proves. The old parallel, serial, mild and plug-in hybrid categories do little to illuminate public understanding of the underlying technology, and much to confuse it. Enter the BYD Dual-Mode, VW “ Twindrive” and, now, the AVL “ Turbohybrid”. With cooperation from BMW, Bosch and LuK, AVL has developed a mild-ish hybrid drivetrain. The consortium claims it’s cheaper and more fun to drive than a “full hybrid” while offering nearly the same efficiency. Care to deep dive?
