So You Think Hybrids Aren't Cool...

Back when I was first kicking off Lexi.Laron, I did features on the renewal and maintenance of my '98 Lexus ES300 with over 250,000 miles on it.  But as I started to realize that I really wanted an RSX Type-S, I decided to focus on making my dream happen.


My baby

But let's put it this way, dreams don't just happen.  Dreams are inspired.  And being that Honda's slogan is "The power of dreams," I find it appropriate that their CR-Z Mugen RR was one of the cars which sparked a flame in my heart and drove me to put my first down payment on that RSX pictured above.

Yet, recently I've questioned Honda's ability to power dreams-- or at least power dreams of speed and screaming VTAK!!!!  Well, for those of you in the same boat as I am, I think that there is really hope that Honda may finally be on the verge of making something cool again...but wait-- it's a hybrid??

I mean yeah, I've been talking about how the CR-Z would come out in a cooler package, but this is the second time that Honda's brought a supercharged CR-Z motor out to SEMA Salon (let alone a whole car), and it's not the first supercharged CR-Z we've seen.  Again, reference that Mugen RR link I have up there^.


And it's always like car companies to come out with concepts of cool cars just to let us down again, but when they bring it out over and over again to major shows around the world, like Nissan did with the GTR concept before they made the R35 GTR, I've seen a higher likelihood that the cars actually get produced.

Anyway, enough chatter.  Let's delve into the details of Honda's most recent showcase for forced induction goodness in a little 1.5 L.

On October 31, 2012 Motor Trend posted an article showcasing the little pitbull talking about modifications made by HPD.  Modifications include a tuned suspension, tuned brakes, exhaust, and new wheels with better tires.

So now...now we talk numbers.  Numbers are always a controversial topic for Honda owners, with some owners boasting about their horsepower per liter numbers while adversaries mock their poor torque numbers.

Yet, as you know with new emissions regulations coming about and with increasing gas prices, it's just not economical to make naturally aspirated engines that rev to 8300 RPM like my K20Z1 does.  No matter how cool it is, it's just not practical.  So that's WHY Honda has chosen the route of forced induction.  By pushing air into your engine it is possible to get more horsepower per liter while also getting great increases in torque as well.

By pairing a hybrid drivetrain with a super capacitor (high power density) and lithium-ion batter (high energy density) with a forced-induction engine with a down-sped crankshaft, the thermodynamic volumetric efficiency of the engine is increased (more horsepower per liter, less fuel consumption), gas is saved, and the torque is all provided by the sudden release of power from the super capacitor which powers the electric motor!  All of this results in a predicted power output of 185 horsepower and 169 ft-lb's of torque.  Those are some pretty well-balanced numbers for a 2500 lb chassis!

So, no it's not a rear-wheel drive car with a low center of gravity and a high-revving engine or turbocharger.  It's a hybrid.  But I'd say it's a pretty cool hybrid.  Maybe Honda is working on the next new thing.  Well, we'll have to see, right?


Until next time, Lexi.Laron is signing out.  Peace.

Motul Civic Si and Other EFs

This is by far my favorite Civic in Gran Turismo: the Mugen Motel Civic Si.




Check out these old-school pics of other late '80s Civic cars.

In Lexus's Repetitive, Recent Attempts to Make Something Cool...

They have made a GS Coupe Concept.


They have made a $375,000 supercar with a v10 engine that revs so quickly, an analog tachometer cannot display the RPMs in an adequate fashion.


And now another overpriced attempt at something that makes sense, but in my eyes makes no sense whatsoever: the Lexus LF-LC Concept.


I'm sure Lexus engineers thought that with a set of angry bee nest-esque grilles and some "infotainment centers" built into their dashboards, they could make a couple of sweet cars!  But I'm not buying it.

Show me something more than a complex instrument cluster that looks like that of an alien space ship's.


Show me something more than a cool looking interior with a sweet computer built into it.


Show me a car, guys.  Show me a freaking car.  Don't take a Scion FR/Subaru BRZ chassis, load it with a bunch of computer parts, have your NASA Rocket Engineers make up some cool tail-lights that look like Mars, and confuse the hell out of me!


I'm young, and maybe that's why I don't understand these things.  Lexus is aimed at the successful business man-- a man with money in his pocket and people to impress.

Lexus, impress my hands when I turn the wheel.  Impress my gut as I fly through corners.  Flatten my butt cheeks with sprinting acceleration.  Do something like the first SC or the second generation GS.  Something with class, but something that's fast with multi-link suspension, front and back, and a decent engine like the 2JZ.  Yamaha-produced and all without the 375,000 dollar price tag.

Kudos to Toyota for sticking to the script.  Let's see if this new car will impress the public at the Detroit Auto Show.

Spoon Sports America; a Tuning Philosophy

Chassis and Subframe Assembly Rigidity

Hello ɭexi.ɭaron viewers!

     Today's addition is a little late, and I apologize for that, but for the tuners out there, I have a story that will stress the linear relation between chassis rigidity and handling.

     Before I go any further, think back to the Swindon Honda Plant post that I made about a week ago.  In the second part of the plant tour video, you get a peek at how engines, suspension, steering racks, and all are assembled to the chassis all at once.

     Well, this is a subframe assembly.

     All of the aforementioned components are mounted to it, and it is jacked up and attached to the bottom of the car's chassis.  When the two are mated, chassis and subframe, there are significant gaps between the threads of the bolt and the threads of the subframe assembly's hole.  Also, there are slight imperfections in between the subframe assembly's and chassis's hard metal which make it hard for the fit and finish to be perfect.  Check out this illustration.

     By placing a piece of special alloy in between the bolt and the subframe and chassis, it is possible to eliminate motion which occurs even when the bolt is torqued.

     This eliminates much of the vertical motion experienced when going over bumps in the road, thus eliminating bump-steer, improving stability and response at all speeds, and lowering road noise.  Check out this video.

Lexus's F Marque; TRD Releases $70,000 Worth of Upgrades for the IS F


So, there's been a lot of talk about the all new Lexus IS F. Well, for those of you who don't know, the "F" in "IS F" stands for something more than flashy body kits or marketing hype. Lexus's finest performance cars are produced under their F Marque Division, and the new IS F is no exception. How can this get any better? How about a TRD package inspired by the Club Circuit Sports Package IS F, revealed at the Tokyo Auto Salon?

The all-new Club Circuit Sports-Inspired Package for the 5.0L, V8 Lexus IS F includes a lot of cool and extremely expensive stuff.

The list price for the whole TRD Package is about $70,000 USD, so you won't see an IS rolling around with parts like these unless you live in Beverly Hills. Regardless, it's pretty cool. Check it out!

Body kit, including air diffusers and carbon fiber galore

A fixed suspension kit (first picture) or an adjustable suspension kit (second), both including sway bars


A handbuilt LSD

TRD Brake Pads, custom magnesium or aluminum wheels, front and rear stabilizers, axle-back exhaust, and carbon fiber interior trim to top it all off.
