lb.-ft.: 365 @ 6,500 r./p.m. manual transmission — 309 @ 1,900 — 5,500; PDK transmission — 317 @ 1,900 — 5,000. Fuel consumption: TBA; premium unleaded fuel. Competition: Chevrolet Corvette, Jaguar F-TYPE SVR, Nissan GT-R. What’s best: Brilliant acceleration; brilliant handling; brilliant brakes. What’s worst: Engine sound a disappointment, but only if you have driven a flat six before. What’s interesting: The most fun Porsche to drive isn’t the fastest one you can buy. Porsche Sport Turismo E-Hybrid. Price: $214,900. Engine: 4.0 L V8, double overhead camshafts, four valves per cylinder, variable valve timing and lift with cylinder shut-off, plus ‘permanently excited’ synchronous electric motor. Power/torque, horsepower / lb-ft: 550 @ 5,700 — 6,000 r.p.m. plus electric motor 136 @ 2,800 / 568 @ 1,960 — 4,500 Fuel consumption: TBA. Premium unleaded fuel Competition: The closest might be the Lexus LS 500 Hybrid sedan — it isn’t all that close. What’s best: As I said about the non-hybrid Sport Touring — styling and performance of a supercar, versatility of a wagon — what’s not to like?; tied with the sedan variant for the fastest hybrid you can buy. What’s worst: Throttle response far too slow; minor touch-screen controls on centre console border on hopeless; fuel-saving hybrid concept seems a bit pointless
