► Lexus IS F 2012
The Lexus IS F is exclusively powered by a performance-tuned 5.0-liter V8 engine teamed to an eight-speed Sport Direct Shift transmission. The IS F engine produces 416 horsepower at 6,600 rpm and 371 lb.-ft. of peak torque at 5,200 rpm. The engine's high specific output (83 hp/liter) and high operating range (6,800 rpm redline) reflect the thorough attention to detail underlying the core engineering. The resulting performance character, while quite responsive in low-speed situations, provides a rush of power at higher engine speeds. The forged crankshaft features journals polished to a mirror finish to minimize the friction generated between the connecting rods and the crankshaft. Forged sintered iron alloy connecting rods ensure high-rpm durability. High-flow cylinder heads designed by Yamaha have a lightweight valvetrain, including forged cam lobes on hollow, chain-driven camshafts, with the inside of the shafts serving as oil passages. Titanium valves are operated by roller rocker arms. Innovative technologies help to maximize efficiency and reduce emissions, including the SFI D-4 fuel injection (direct-to-cylinder injection system with secondary port injectors) and the Electronic Throttle Control System with intelligence (ETCS-i). Essentially, SFI D-4 integrates two types of fuel injection: A direct-type high-pressure fuel injection system, which provides a cooling effect in the cylinders and enables the high compression ratio (11.8:1) employed to extract maximum energy from the fuel; a set of low-pressure port fuel injectors that help produce a precise burn to optimize power and efficiency under light- and medium-load conditions. A dual air-intake system uses a primary intake passage for low and medium engine speeds. In the higher engine speed range (above 3,600 rpm), both the primary and secondary passages are opened, helping Boost high-rpm power. With the IS F 5.0-liter V8, Lexus made a leap in valve-control technology with the Variable Valve Timing with intelligence by an electric motor (VVT-iE). An electric drive motor alters the intake camshaft phasing, which made it possible to expand VVT operational range to lower engine speeds, where engine oil pressure is usually not high enough to operate conventional VVT. The Exhaust camshaft uses hydraulically controlled variable valve timing. A scavenge pump forces oil from the cylinder heads back to the oil pan, ensuring a reliable oil supply even during cornering that exceeds one g. The low-restriction dual-Exhaust system terminates in distinctive stacked quad diffusers. The world's first eight-speed Sport Direct-Shift automatic transmission combines the performance characteristics of an automated manual-type transmission with the smoothness and refinement of a planetary-type automatic transmission. As a result, the driver can choose between ultra-quick manual shifts for performance driving and smooth automatic shifts when convenience is the top priority. Eight speeds allow gear ratios that maximize torque up to the tire-grip limitations in the lower ranges while optimizing efficiency. Intuitive powertrain control optimally smoothes out off-the-line response. The driver can select Normal, Sport or Snow driving modes with the flip of a switch. Artificial Intelligence-SHIFT (AI-SHIFT) complements the driver's Sport switch selection by automatically adapting the shifting based on road conditions and driver input. The IS F transmission is also highly responsive to uphill/downhill driving, always selecting the best gear for power or engine braking. The driver can shift manually using either the console shift or steering-wheel-mounted paddle shifters. Hydraulic-control technology allows the IS F's eight-speed Sport Direct Shift transmission to perform on par with manual transmissions without sacrificing the smoothness of a torque-converter automatic. Paddle-shifting operation is allowed in either D or M modes, but shifts are quicker and more direct in M mode. In M mode, the transmission will hold each gear to the 6,800-rpm redline, and upshifts are executed in just one-tenth of a second. At higher engine speeds, downshifts are accompanied by automated and precise throttle blips to match engine rpm to vehicle speed.

2012 Lexus IS F: Toyota's Turning Point? - Ignition Episode 33
On this episode of Ignition, Carlos Lago pilots the 2012 Lexus IS F at the test track and on the winding road. The IS F may have ushered in the rebirth of sporty, fun-to-drive cars for Toyota, but how does it stack up today against formidable competitors like the BMW M3 and Mercedes-Benz C63?
