    If we just see the power per CC then it tun out that for city it is 118/1.497= 78.8 per cc
    89 BHP of 1.4 tur out o be 89/1.368= 65.05 per cc

    So here Vtec clearly ahead of FIRE. But for Tjet the corresponding ratio is 83.33per cc :) way ahead Vtec.
    The latest non turbo Multiair produces 105 BHP which turn out be 105/1.368=76.7 per CC

    I am not mixing the dynamics here which we can discuss in another relevant thread. Let us stick to only Engine.

    Correct. Why all these calculations? The 1.2L Vtec used in Jazz itself churns out 90 BHP.

    But city is more efficient in terms of power per CC. For Jazz it is 75.1 compared to 78.8 of city:)
    For civic it is even less 73.4 and for accord 2.4 ivtec it is 76.4. For Accord 3.5V6 it is 79.2 which is highest.

    Correct. I gave this example to compare it with 1.4 Fire which also churns out the same 90HP. :D

  5. How difficult for them to Plonk a turbo charger on City's engine,that will just blow away Tjet's advantage as os of now.

    Guys, don't compare NA and Turbo engines! Compare the T-Jet with the 1.4 TFSI if you want. Turbo engines can make ridiculous power from limited displacements. The BMW 1.5 three cylinder petrol is already putting out 220bhp in it's most extreme avatar!

    x-x-x

    I don't see any motivation on the part of the Japs to build small turbo petrols, as of today.

    The major sales are in the mass-market segment, which is ruled by the 1.0 & 1.2's. In the C&D segment, the diesels are ruling big time. Toyota just made a half hearted attempt at giving the Corolla a diesel.

    Unless the diesel pricing is deregulated completely or the next gen emission standards are way too harsh to be met by the present engines, i don't see any turbo petrols by them.

    All said and done, the Europeans are wayy ahead when it comes to bringing out brilliant engines today. The Japs have pretty much lost the plot. Even in India, outside of the mass-market segment, they don't really have a quality offering to match the Europeans and the lack of a diesel option is harming even more. Even the Koreans are beating them.

    Honda should be looking at a 1.2 Turbo Petrol to replace the City engine, if at all. The 1.5 turbopetrol, if any, should find it's way into the Civic platform.

  7. Japs are quite clever is it not,outside of mass market is low numbers may bit high profit but also needs large investments with out much sales like Mercedes India.
    Economists control these companies and they are there where the business is luracative

    Europeans had a great heritage. Japanese are late entries. It matters when it come to conventional technologies and their improvements alongside with technological development. Technologies will sometime undergo a phase transition, a new era in which the conventional technologies have to give space to newer ones. The Japanese might have gathered enough knowledge to get advantage in next level of automobile technologies though it may not be happening in near future. They are as good or advanced as US and Europe in terms of nano technologies and materiel sciences.

    Europeans are innovator's, Japanese are improviser's.
