Let me know what you think! Find out now. And because lubrication was supplied at a constant pressure, the oil could not cavitate from where it was needed. The response was so fast, that a specially designed digital TFT LCD rev counter was used just to keep up!
Have you ever wondered what if Toyota made the LF-A back in 1997 though? Even though the exact weight of the engine has never been officially revealed, it is rumored to weigh less than the 3.5-liter 2GR-FE V6 engine. .

Direct airflow into the engine was a key element in the hyper-responsive feeling through the throttle. Do you think this would’ve sold well? Extensive airflow diagnostics and engineering have resulted in excellent front and rear downforce distribution, superb high-speed stability and an exotic yet aerodynamic profile. When engine speed exceeds 9000 rpm, the display area turns red to prime the driver for an up-shift. Enjoy the epic sound! . Do these parts fit your vehicle?
Its maximum torque output of 480 N⋅m (354 lb⋅ft) arrives at 6,800 rpm, 90 percent of which is available from 3,700 rpm. The LFA is a perfectly balanced supercar, delivering lightning quick responses, much like an extension of your own body. Making the LFA was one of the greatest engineering challenges ever undertaken by Lexus. Surprisingly compact and constructed from exotic aluminium, magnesium and titanium alloys, the dimensions of the engine were equivalent to that of a traditional V8 yet it remained as light as a conventional V6. Learn more about Price, Engine Type, MPG, and complete safety and warranty information. Has any other engine been able to compete with its induction roar?
This short, direct airflow into the engine was a key element in the hyper-responsive feeling coming through the throttle. Three acoustically optimised sound channels ensured the LFA’s cabin was filled with the engine…
The engineers described the sound of the engine as "the roar of an Angel". For Haruhiko Tanahashi and his team, overcoming the challenge of completing the award-winning LFA design is an accomplishment that has carved out well-deserved space for them in the annals of motoring history. Four months after being given the go-ahead for the study, Tanahashi recorded in his diary that the first product meeting on June 26, 2000 proposed a V6 open-top sports car. This makes it the most powerful Lexus ever. The engine redlines at 9,000 rpm, but with a fuel cutoff set at 9,500 rpm, and is constructed using forged aluminum pistons, forged titanium connecting rods, and solid titani… Most vehicles start with the engine, with the rest of the car designed around it. The LFA's sleek and athletic body is the result of hundreds of hours of wind-tunnel testing and thousands of hours of computer modelling. Harmonic management was also used at the titanium dual-stage rear silencer, which incorporated a valve-actuated structure to either minimise or maximise exhaust sound. In 2017, Lexus … The V10 design held several advantages over other equivalent displacement layouts: V8 wouldn’t be able to rev as high whilst the reciprocating mass and increased friction of a V12 would eat away at performance. 65% of the vehicle’s total body mass is CFRP, while the remaining 35% is aluminium, saving 100 kg (220 lbs) over the original aluminum design. Engines & Components for Lexus LFA. In fact, because the LFA's engine can rev from idle to 9,000 rpm in just six tenths of a second, a digital rev counter was required as an analogue system simply couldn't keep pace. autoevolution® and the autoevolution® logo are registered trademarks. The engine had to rev to 9,000 rpm, with the fuel cutoff set at 9,500 rpm. Lexus LFA | Lexus. To further reduce weight, the original aluminium alloy chassis was redesigned to be produced in-house as a carbon fiber reinforced polymer (CFRP) tub, with bolt-on aluminum front and rear subframes. Using this driver input information, the system was able to prime each 12-hole injector to deliver the appropriate volume of fuel for any given engine speed and load. C'est le second modèle de la ligne F (sportif) après l'IS F de fin 2007, mais surtout la première supercar du constructeur nippon. In October 2000, Chief Engineer Haruhiko Tanahashi and his team embarked on their greatest engineering challenge yet. Learn how your comment data is processed.

The engine redlines at 9000 rpm and has a fuel cut-off at 9500 rpm, with 90% of its peak torque available from 3,700 rpm to 9,000 rpm. After combustion, spent exhaust gases exited through a true dual system beginning with equal-length exhaust manifold runners, a layout that enhanced torque through optimised back pressure and created a crisp sound quality.
It also created a neat valley that was used to position both the oil cooler and positive crankcase ventilation chamber. Above 3,000rpm all sound-deadening chambers were by-passed; the exit route straightened and the engine announced its delight at being unleashed with a spine-tingling scream.
The LFA’s valves were made from titanium and each rocker arm (above left) featured an integrated oil jet. By deleting the traditional wet sump from the bottom of the engine and directing oil to specific parts through an external ventricular arrangement, the V10 was able to be located deep within the chassis.
