Honda Previews New Engine Lineup: Direct Injection and CVTs Coming

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.

New Honda Earth Dreams Technology 1.6L diesel in Civic to deliver CO2 emissions of 95 g/km

 

Honda’s new 1.6-liter i-DTEC engine in the new Civic will deliver CO2 emissions of 95 g/km, according to Honda Motor Europe’s President, Manabu Nishimae, in his presentation at the Geneva Motor Show. This is a 15-gram drop (13.6%) from the 110 g/km emissions of the enhanced 2.2L i-DTEC introduced in September 2011 at the Frankfurt show. (Earlier post.)
The 1.6-liter i-DTEC offers maximum power output of 118 hp (88 kW) at 4000 rpm, and 300 N·m (221 lb-ft) of torque at 2000 rpm). The new 1.6-liter i-DTEC engine is the first of Honda’s new Earth Dreams Technology engine series (earlier post) to be introduced into Europe. It will be manufactured at Honda’s UK manufacturing facility in Swindon from the end of 2012.

The application of new high-strength material in the cylinder head has enabled Honda to deliver the world’s lightest aluminium open deck 1.6-liter diesel engine.
By downsizing from the outgoing 2.2L engine and extensively reducing mechanical friction in each section, a friction level equivalent to present gasoline engine models was achieved.
The engine features an optimized thermal management system due to improvements in the cooling system. A compact, high-efficiency turbocharger and weight reduction in the reciprocating sliding section realizes a sporty and nimble ride, according to Honda.
Honda will also renew our entire European engine line-up, with a new engine series called Earth Dreams Technology. With these engines we aim to be Number 1 in fuel economy in each sector within 3 years.
