Honda Previews New Engine Lineup: Direct Injection and CVTs Coming

Much has been said about the new Honda Civic receiving a list of early updates in a bid to silence critics while restoring the car’s class-leading fuel economy. This has all but been confirmed, with the Japanese automaker revealing an entire new lineup of engines and transmissions at a press briefing held at the Twin Ring Motegi Racing Circuit on the eve of the Tokyo Motor Show.

In total, Honda unveiled five all-new engines, ranging from a new Kei car 660 cc motor, to a flagship 3.5-liter V6 powertrain. With these engines Honda has said it is committed to being both a leader in fuel economy and engine output.

Engines destined for North America include a new 1.5-liter, 1.8-liter and 2.4-liter 4-cylinder, as well as a 3.5-liter V6. Across the board, all will receive direct-injection technology. The 4-cylinder engines gain a new VTEC arrangement with an Atkinson cycle lower load cam plus extensive friction reduction technologies. The result on a car like the Civic will be a 10 percent improvement in fuel economy, plus a 5 percent increase in power over the current model. The same goes for the 2.4-liter, which one Honda representative told us the new 2012 CR-V just missed out on receiving.

As for the V6 engine, it will replace both the current 3.5-liter and 3.7-liter engines, combining the best technologies of both, including a cylinder deactivation system while gaining direct injection. Honda provided a preliminary, and conservative, estimated power output with 310-hp and 265 lb-ft of torque, with a much stronger torque band.

Of note, all of the engines included a start-stop function, although no decision has been made by Honda as to whether we’ll see this technology in North America.

Apart from the new dual-clutch 7-speed transmission (integrated into a new SH-AW, discussion of automatics at the Honda event was non-existent. Instead, Honda revealed several new CVTs (and yes, they can hear you groaning in Motegi). Of note is a new CVT designed for compact cars, as well as another for mid-size, meaning you should look for CVTs to find their way into cars like the Civic, Accord and CR-V soon. As terrible as all this may sound for Honda owners dreading the thought of a CVT, the good news is what Honda is calling “G-Design Shift”, which was created to help deliver more immediate throttle response. We did have the change to test out the new CVT in a 2.4-liter direct-injection TSX but we can’t tell you about it until the embargo lifts next week. Stay tuned.

    Or its homogeneous or its stratified the words mean the oposite of each other and, no HCCI is not like diesel at all. Diesel did not invent auto-ignition, it has always been there. Hes just found a way of using it without harming the engine by introducing gradually a very reactiv fuel so combustion starts and then flooding the chamber with more fuel so the rest of the fuel burns by difusion (fuel will burn slowly if theres no suficient air to react with. Thats why it makes so much smoke at full load). HCCI combustion can damage an engine if load is too high or mixture too rich because its homogeneous (well mixed). So Diesel is stratified and HCCI is homogeneous.

    I hope the new 2013 Accord with CVT is tested adequately to assure it is more dependable then the former Automatic transmissions.
