Honda reveals the Advanced VTEC engine
Honda's engineers have been busily figuring out how to make their VTEC engine better, and today the auto giant released the first details about the next-generation powerplant, which they're calling Advanced VTEC. Honda says it plans to have the new engine in a production car within the next three years.
Torquier at all speeds, the engine also sets the valves for low lift and early closure at lower load levels, which boosts fuel economy to the tune of 13% over the current 2.4L i-VTEC when the engine is equipped with the proper intake bits. In addition to being punchier and more economical, the engine is cleaner-burning as well, garnering a LEV2-ULEV emissions rating.
This is good news. While research and implementation of the various alternative fuel and propulsion solutions is most welcome, there's a lot to be said for the regular, economical four-cylinder gasoline engine. If Honda is on the verge of producing a four with power, more torque (hooray!), better fuel economy and cleaner emissions, the Advanced VTEC is going to be a highly attractive alternative to the alternatives.

PRESS RELEASE:
Honda Develops Advanced VTEC Engine Combining High Power and Environmental Performance
September 25, 2006–Honda Motor Co., Ltd. has further advanced its VTEC (Variable Valve Timing and Lift Electronic Control System) technology with the development of the Advanced VTEC engine, which achieves high performance along with outstanding fuel economy and lower emissions. The new engine combines continuously variable valve lift and timing control with the continuously variable phase control of VTC (Variable Timing Control). Honda plans to release a production vehicle equipped with the new engine within three years.
This new system permits optimum control over intake valve lift and phase in response to driving conditions, achieving improved charging efficiency for a significant increase in torque at all engine speeds. Under low to medium load levels, the valves are set for low lift and early closure to reduce pumping losses and improve fuel economy.
In combination with optimized intake components, these advances in control technology result in world-class dynamic performance along with approximately 13%* improvement in fuel economy. The new engine is also exceptionally clean, with exhaust emissions that meet both U.S. Environmental Protection Agency LEV2-ULEV regulations and Japanese Ministry of Land, Infrastructure and Transport requirements for Low-Emission Vehicles, with emission levels 75% lower than those required by the 2005 standards (based on Honda calculations).
* Engine only, as compared to production 2.4-liter i-VTEC engine (Honda calculations)

IN 1998 HONDA ACCORD FUTURET A 2.3L VTEC ENGINE PRODUCING 150HP AT 6500RPM
A SPEED LIMITER WAS NOT INSTALT IN THE LX AND EX MODEL BECAUSES THIS CARS ARE LIMITED BY THE RPM LIMITER.THE SPEED LIMITER CAME ON A DX MODEL ONLY AND RPM LIMITER BECAUSES THE TIMING WAS DIFFRENT FROM LX AND EX.
THE TOP SPEED'S ON THE ACCORDS
H-LX.2.3L 157MPH RPM LIMITED
H-EX.2.3L 155MPH RPM LIMITED
H-DX.2.3L 125MPH SPEED LIMITED RPM LIMITED
H-V6.3.0L 172MPH RPM LIMITED
-------------------------------------------------------
ALL CARS HONDAS IN 2003 HAVE INSTALLT A SPEED LIMITER AT 138MPH V6-V4 CYLINDERS AND RPM LIMITED ONLY IN THE USA-IN EUROPE NOT
BECAUSES IN 1998 2002 HONDA ACCORD'S AND THE COMPANY DID NOT INSTALL SPEED LIMITER'S ON LX AND EX MODELS THE GOVERMENT SET IT ON THE ECM BECAUSES THE CARS OVERDRIVE THE LIMITS...

THE DX MODEL CAME IN 2 DIFFRENT
ED MOTOR A 2.2L AND A 2.3L IN EUROPE
IN USA 2.2L
-------------------------------------------
IT'S EASY AS 1.2.3 TOO DISABLE THE SPEED LIMITER ON ALL ACCORD'S AND HONDA CIVIC'S
BECAUSES THE ECM IT'S THE SAME AS EUROPE
AND ALL HONDA ECM'S ARE THE SAME JUST DIFFRENT PROGRAMMS RUNUNG IT YOU CAN DOWNLOAD A FREE SOFTWARE FROM HONDADATA.COM
AND FIND CABLES THATE FIT FROM A LAPTOP TOO THE ECM UNTER THE DRIVERS SIDE.
POPLE WODER IT'S THE HORSEPOWER LIMITED I SAY YES A HONDA ACCORD ENGINE 4C CAN PRODUCE 280HP
SOO YOU CAN GO FROM 150HP TOO 280HP WITH NO INTAKE NO TURBO. AND SAME PEOPLE WONDER CAN I GO IN THE CIVIC I SAY YES A CIVIC PRODUCING 120HP CAN GOO TO 190HP..SOO PEOPLE ASK MY WHAT WILL IT TAKE I SAY A PROGRAMM FROM HONDADATE.COM AND A LEPTOP AND A CABLE THE GOSE FROM USB TOO THE ECM..ALL ENGINES ARE LIMITED BY RPM OR SPEEDLIMITER.

PEOPLE SEND MY EMAIL'S AND ASK'T MY WHAT'S THE BEST RPM A HONDA ENGINE GAN HANDLE
THE ANSWERS.
A HONDA ACCORD ENGINE VTEC OR VTEC DOHC TYPE R CAN BY MAX'T AT 10.222RPM.DO NOT EXCIDE TOO 11.000RPM
ALL CIVIC VTEC DOHC OR VTEC CAN MAX AT 12.729RPM MAX
AND YOU CAN DO IT ALL ON THE ECM YOU NEED A INTAKE ONLY AND ECM PROGRAMM FROM HONDADATA.COM

Just wanted to point out that Honda did not "release a production vehicle equipped with the new engine within three years." of the press release on September 25, 2009. Honda has been lacking of late in significantly improving their combustion engines.

Finally! The others had been catching up (Toyota, GM, BMW, VW/Audi)... If they can get this into something soon they'll return to the Ward's 10 best engines list in no time.
It's gotta be the next-gen Accord base engine, IMO. Can Accord reclaim the "America's Favorite Car" throne from Camry with this thing?

As I typed earlier, Honda still has a lot of room for imporvement with GAS engines and this news is a testament to that. All we hear about is how bad engines are ---AL THE WHORE GORE---but Honda has continually improved the performance, emissions, and mileage of their engines.
If they can figure out how to get their vtec engines more low end torque while improving gas mileage, Honda will do much to over take Toyota in sales.

Say what you want about Honda, but they make some of the best engines in the world. From an engineering standpoint, I'll take the Honda over the Toyota any day. I can't wait to see this on the market.

I'd like to see other automakers license this technology instead of trying to reinvent it. I wonder if Advanced VTEC would be equally beneficial to DOHC V8s?

Put this on the K23 turbo going into the next TSX.

Honda has at least two 2.4L engines. One gets 166hp/160ft-lbs and goes in the US Accord for 34mpg hwy. The other gets 205hp/164ft-lbs and goes in the Acura TSX for 30mph hwy. The latter generates max hp at 7000rpm instead of 5800rpm.
I wonder which of the two were used as the base engine, and if the improvements will be seen in both the TSX and Accord. Pictured above is a European Accord, aka TSX.
*numbers are from Edmunds for manual transmissions. Also of note is that the TSX weighs 89 lbs (or about 3%) more.

Good to hear. As great as Honda four cylinders are, the competition has pretty much caught up at this point – and they're getting some torque out of 'em, too.
As a side note, seems like they could've kept the RSX upmarket if the turbo 2.3 fit in there. Giving Acura turbos and keeping Honda NA would be interesting.
