Honda Trademarks ZSX Nameplate, Is It For A Baby NSX?

It seems increasingly likely that a baby brother to the Honda NSX could be on the way, following confirmation that Honda trademarked ZSX with the European Union Intellectual Property Office on July 26.

While automakers trademark names all the time simply to protect them, rather than having the intention of bringing them to the market, the similarity between ZSX and NSX has certainly raised eyebrows and sent tongues wagging.

Interestingly, Honda has trademarked the name ZSX previously, albeit in the United States. That trademark however lapsed on December 10, 2012 but conceivably, may be snapped up by the Japanese company once again.

While speaking with French publication Automoto, a reported Honda engineer says that the company will launch the ZSX in concept guise at the Detroit Motor Show 2017 in January.

Apparently the car will debut as a hybrid coupe concept, utilizing the Civic Type R's 2.0-liter turbocharged four-cylinder engine coupled to two electric motors, each driving a rear wheel.

Revived Honda S2000 May Get 320 HP Twin-Charged Inline-Four

Quote:

There are a handful of automotive rumors that have persisted for so long that you could be forgiven for believing they’re nothing more than wishful thinking. Among them are talks of a next-generation Honda S2000.

The Japanese company is a very different brand to what it was in the late 1990s and early 2000s when it produced some of the market’s best front-wheel drive hatches and of course, the rear-wheel S2000. Nowadays the brand is all about fuel-efficient vehicles that appeal to the masses.

Fortunately, it seems things are changing following the release of the latest Honda NSX and these changes are set to include a revived S2000, according to Car and Driver.

It is thought that Honda is planning to release a new S2000 in 2018 to mark its 70th anniversary and 20 years since the original S2000 was launched. Previously, it was widely reported that the Civic Type R’s turbo’d 2.0-liter would find its way into the new S2K but apparently, something much more exciting is in the works.

Honda is preparing to take a page out of Mitsubishi’s book by developing an all-new powertrain that incorporates a turbocharger and an electrically driven supercharger aimed at eliminating turbo lag while being more fuel efficient than current twin-turbo systems. These components will then be bolted to a 2.0-liter inline-four cylinder engine designed to pump out in excess of 320 hp.

Car and Driver says that this new powertrain will come mated to a dual-clutch eight-speed transmission. However, considering that Honda continues to offer many of its cars with manual gearboxes to this day, we’re holding out hope a traditional stick shift will also be made available.

If the new-age Honda S2000 does indeed launch in 2018, a debut at the Paris Auto Show in September next year or the Los Angeles Auto Show in November 2018 are likely candidates to host the unveiling.

The biggest problem was really the oil pan, which for some reason was unbaffled whereas the 1ZZ oil pan had at least some baffling. Super easy to kill the engine from oil starvation.

If you wanted to run that thing over 8000rpm regularly, the stock valves would need to be thrown out and replaced with aftermarket, and probably the oil pump gears too. The stock valves were weak would break off the stem and wreck the engine. The lift bolts also were redesigned for reliability later one.

The C series transmissions were somewhat fragile too, which is another reason why K20 swaps are somewhat popular (even though you're not gaining much power for the trouble) for Elise/MR2s.

You're very correct about the consumer. Consumers these days like torquey small turbos, because they make the car feel really fast when you're not pushing it. Every manufacturer is toting the big increase in torque from switching to turbo engines for a reason. The hardcore car enthusiast that likes to shift gears to access the powerband is dying out :(

No, the friction from operating the valves is nearly negligible. The heat loss at lower rpm from increasing the bore:stroke ratio is also nearly negligible; Toyota found a 1% decrease in fuel efficiency going from the 90mm stroke in the 1ZZ to 85mm stroke in the 2ZZ.

The K series had been around for a decade by the time they had to retire the K20, that's about what you'd expect.

One big reason why you only see high revving engines in supercars now is that a high revving engine usually uses shorter low gears so people don't complain about "lack of torque", but then the shorter low gears wreck your EPA certification mpg. In the real world the mpg decrease is not that big, unless the top gear is too short like a E90 M3 or S2000, and you can get around it like the American manufacturers did using custom shift schedules. For whatever reason, no one has bothered specifying shift schedules to game the numbers, I guess they figure people aren't that interested in manual transmissions anymore.

In a supercar this isn't a problem because they have so much power no one is going to complain that their car is slow and needs a supercharger. Well...almost no one lol.

When the Celica GT-S debuted in the US it DID have an 8300 rpm redline. Toyota lowered the redline a few years later; something to do with transmission problems related to tight/inaccurate shifting gates...my reason may be off but my memory about the change in redline is not.

A twin-charged 4 cylinder sounds like a nightmare to work on.

The days of powerful NA 4cylinder engines are gone.

I have a 2000 GTS ECU, it tops out at something like 8250. They did indeed drop it to 7900 later.

Guys who race the 2zz on Spyderchat recommend not going over 8000 continuously because the reliability is not so good on the track.

The description they gave was not for a twin charged engine, it sounds like an electric turbo just like the ones in F1. It shouldn't be much more complicated than a normal turbo.

I am also okay with them offering an automatic transmission to improve sales, as long as it comes with a stick option.

However I would rather they spend money on making a light, strong chassis and good suspension than some fancy turbo engine. I don't understand what is so bad about a naturally aspirated K24 or R18, which would be adequate if they get the curb weight low.

That's kind of sad. You would expect better of Toyota.

Agreed. Have you heard about the Ballard Motorsports project to offer a kit to convert the F20C to 2.4 liters using mostly Honda OEM parts?

Pretty slick IMO: http://www.s2ki.com/forums/s2000-nat...-2-4l-1161441/

Yep +1. If the brz/86 has shown anything, it's to focus on the chassis. However given the possible price range the rumored s2k might sit it (i.e. more than civic type r) it's unlikely to be low on power.

I'd be happy with a 1000kg chassis with an R18 engine. They are very good for forced induction (more so than a FA20!) and a cheap platform to run for Honda. It would also serve the purpose of boosting the honda heirarchy which is important for sales. This is like the old days where b series were cross compatible and you worked your way up from a d16 to a b18cr along with a few difference chassis of the way.

Shouldnt they make a new Honda in the year 3000 instead? it seems more appropriate and call it S3000

That could explain why the 2ZZ-GE has so little aftermarket support...
And why the Celica never did manage to deliver sustained competition to the Integra or RSX...

Not a big fan of the iron liners, I feel like 2.2L to 2.4L isn't enough of an improvement for all that trouble. Might as well use a K24 right?

I just did some research on the L15B7 and K20C2. It appears that the L15B7 is vastly underrated at "176hp", it is easily a 190-200ish hp engine on 87 gas, and probably 230hp with a tune. The bad part is that the EX-T Civic weighs 110 lbs more than the LX Civic, and the only things they added were some sensors and of course the engine. I imagine that the turbo would allow a few pounds to be taken out of the muffler for equal loudness, and the transmission might be a little heavier, so I'll call it a 90lbs difference.

The K20C is "lighter than the previous generation", which is the R18. The R18 was probably around 230-240lbs with all fluids, so I think you can probably say the K20C is something like 230lbs, which is insanely light. Turns out the K20C also seems to have some potential that Honda hasn't been advertising, because it makes peak power basically right at the rev limiter, and it has the same 86mm bore and stroke as the K20A.

If you add 90lbs to 230, you get 320lbs, which is a fairly normal weight for a turbo 4, though a bit on the heavy side for a 1.5L. So it's possible the K20C is actually even lighter, which would be amazing. The integrated exhaust manifold is not good for power, but you can overcome that with a Rotrex.

If Honda builds this car, they should just grab the K20C2 from the Civic, fit 12.0 compression ratio pistons, spec 91 fuel, and raise that silly 6700rpm rev limiter, which should get close to the 200hp mark from the factory. It seems like a fantastic engine as is, and has much of the potential of the K20Z3/A. With an engine this light, keeping the curb weight under 1100kg should be a piece of cake.

I was under the impression that Toyota ecu is tough to break for any flash, you can only go piggy back.

Another +1 for Ballade Sports here. I was a customer of theirs for years and Alex the owner is a very stand up community driven guy. Best Honda shop in Southern California in my opinion!
