7.5 liter. 750hp Cadillac motor. Honda is not ahead of American car companies technologically.

damn

 

Here are a few interesting facts that are shown on their "concept" car...looks like someone let the engineers loose and told them to have fun.

Displacement on Demand
The cylinder shutdown is enabled through valve deactivation, which is performed by a compact switchable tappet. Cylinder de-activation occurs on the right-hand bank only, which allows the engine to run as a perfectly balanced inline 6-cylinder. The system deactivation and reactivation has a quick response time and the oil system and solenoid layout allows valve switching capability at up to 6000 rpm. In May 2001, GM announced that it will implement Displacement on Demand in its trucks and SUVs beginning in 2004.

Direct Injection Gasoline
Using a direct-injection gasoline combustion system provides an increase in engine power and also improves fuel economy and cold-start hydrocarbon emissions. The multiple injection set-up also improves emissions and performance through faster catalyst light-off. The single fluid high-pressure fuel injector is centrally located in the combustion chamber, and sprays the fuel vertically down to the piston.

Variable Cam Phasing
The use of variable cam phasing helps the Northstar XV12 achieve 90 percent of its maximum torque at 1500 rpm, improves combustion stability at idle, improves fuel economy by reducing pumping losses and can be used to speed up catalyst light-off to significantly improve emissions. It provides internal exhaust gas recirculation (EGR), which is more reliable and cost-effective than an external EGR set-up.

Variable Intake Manifold
The Northstar XV12's three-stage variable induction system with tuned primary and secondary pipes results in a flat torque curve. It's a simple, compact and reliable design. Electric variable intake valve actuators enable rapid changes in manifold geometry over conventional pneumatic actuators.

Rear Chain Timing Drive
Many of the engine's accessories are run off the rear chain timing drive, creating opportunities for better packaging by eliminating the need for a front engine accessory drive and reducing the engine's overall length, as well as the height of its front end. The robust yet quiet-running chain drives the engine's camshafts, high-pressure fuel pump, oil pump, and hydraulic power-assist steering pump, and also has the potential to drive the water pump and air conditioning compressor.

36,000-Mile Oil Change Interval
The Northstar XV12 is designed for 36,000-mile intervals between oil changes. This is achieved through a combination of improved oil sensors and monitors, reduced oil consumption, oil cooling and a larger oil sump capacity.

 

I am sure that engine will never be in a Cadillac street car, and cost as much as a Honda. Notice in the article that Cadillac enlisted Cosworth, a racing engine development company, based in England. The technology has been employed by Honda for years, and only now does an American company go out of thier way and hire someone to design an efficient engine. Remember the ZR-1 Corvette's LT-5 V-8? The DOHC, 5.7L engine? Designed by Lotus, built by Mercury Marine.

Considering Honda's vast experience in Formula One and GP bikes, I say that they are several steps ahead, especially when you consider that their are no American manufacturers competing in Formula One or GP.

Also, think about how small Honda is compared to GM. GM has much more money to throw around.

 

that's okay. 1st it's a concept engine, mass production is still couple years away. 2. b16a was the first mass produced automotive engine to 100 hp/liter. that was done in 1988... 13 years ago. the b16a in my 95 delsol which is basically the same exact b16a introduced in 1988 is making over 125 hp/liter (i have just over 200 crank hp) with stock internals. and my friend's race b16a is making 150 hp/liter (240 crank hp in 1.6 liter).

honda's engines are easily accessible.

with all that said, that engine's spec sheet looks very impressive. drop that into a vette c5 chassis. what a real beast.

Well the ITR makes 108hp per litre, the S2000 120hp per litre and the new ITR 110hp per litre so actually Honda is still ahead

 

Hahahahahahahahaha...LMAO...Who is this joker that keeps posting these posts? (***Not referring to Sam & Bridget***)

Here's one for you buddy... ok, that was 5...

No Hondas in Winston Cup Racing! I'm not trying to start a flame war. I was just trying to inlighten some of the people who hug the hondas like rednicks hug their V8s. You gotta respect V8s and V12s and Americans in general cuz their motors are BEAST. I got two words for you 502 hemi. I personally have more respect for V8s cuz on the street they are the only cars that can hang with me. That is with street tires NOT in slicks. No doubt 100 per liter is amazing but the V8s that are only 50 hp per liter run 13s STOCK.


GOOD comeback ILOVERACING.....that was sarcasm

Well ford is in F1. Remember Jaguar runs Ford Cosworth engines.
Which is kinda funny that GM still bigger then Ford is buying technology and such from there main competitor..but it thats not the first time thats happen it's been happening alot overseas. Still not sure why there just letting there F-body cars after this yr.. I know sales are bad so why not redo the car or something?! Well this thread is getting locked before it get out hand.

 

Actually with the new V8 2 door RL coming soon I wouldn't doubt they try to get into winston cup. Why would they build so close to the track here. That was actually one of the main reasons to come here for testing cars on the oval and new road course coming soon.
