2017 honda civic si coupe revealed 8211 1 5t upgraded for si duty coupe and sedan

We’re far removed from the 91-horsepower 1984 Honda Civic Si.

Honda, on the eve of the 2016 Los Angeles Auto Show, introduced the Si version of the tenth-generation Civic in prototype coupe form. Honda plans to bring the Si to market as a 2017 model next year with both sedan and coupe bodystyles.

Expect very few changes for the coupe when this “prototype” becomes a production car next year. In Honda vernacular, “prototype” is as close to production as a production car can be without actually being the production car.

Details are relatively scarce. Honda says the new Civic Si will feature adaptive suspension and active steering for the first time in a Civic. There’ll be a limited-slip differential and, if the prototype’s Honda Factory Performance additions make it to production, 19-inch wheels with 235/35Y rubber.

The 1.5-liter turbocharged four-cylinder introduced as an optional upgrade in the sedan and coupe — and as standard equipment on the new 2017 Honda Civic Hatchback — is under the hood of the Si with enough power to make the 2017 Civic Si, according to Honda’s Jeff Conrad, “hands down, the fastest, best-handling Si we’ve ever offered to our customers.”

The 1.5T makes as much as 180 horsepower in the non-Si Civic; 190 in the new CR-V. We expect more than 220 horsepower in the production Civic Si, up from the 205 made by the 2.4-liter naturally aspirated four-cylinder in the ninth-gen Civic Si.

As Honda already made clear with the debut of a Civic Type R Prototype at this year’s Paris auto show, the Si will no longer be the highest-performance Civic. The current Type R, not sold in North America, produces 306 horsepower, clearly distinguishing the two performance Civics. The production Type R, built in the UK, will reach the market after the Si variants.

    All I know is that coming up behind one at speed at 3 a.m. is a vision of confusion. Those lights look like nothing else.

    M3: 150hp/liter Honda: 150 x 1.5: 225?

  • Jeff S I am not a fan of Tesla and they were niche vehicles but it seems that they have become more common. I doubt if I get an EV that it would be a Tesla. The electrical grid will have to be expanded because people over the long run are not going to accept the excuse of the grid can't handle people charging their EVs.
  • AMcA The '70 Continentals and Town Cars may have been cousins to the standard body Fords and Mercurys, they didn't have to be disguised, because they had unique, unbelievably huge bodies of their own. Looking at the new 1970 interior, I'd say it was also a cost savings in sewing the seat. Button tufted panels like the 1969 interior had require a lot of sewing and tufting work. The 1970 interior is mostly surface sewing on a single sheet of upholstery instead of laboriously assembled smaller pieces. FINALLY: do I remember correctly that the shag carpet shown under these cars was a Photoshop? They didn't really go so peak '70s as to photograph cars on shag carpets, did they?
  • Inside Looking Out Toyota makes mass market cars. Their statement means that EVs are not mass market yet. But then Tesla managed to make mass market car - Mode; 3. Where I live in CA there are more Tesla Model 3s on streets than Corollas.
  • Ltcmgm78 A lot of dirt must turn before there's an EV in every driveway. There must be a national infrastructure plan written by other than politicians chasing votes. There must be reliable batteries that hopefully aren't sourced from strategic rivals. There must be a way to charge a lot of EVs. Toyota is wisely holding their water. There is a danger in urging unplanned and hasty moves away from ICE vehicles. Do we want to listen to unending speeches every election cycle that we are closer than we have ever been to 100% electrification and that voting for certain folks will make it happen faster? Picture every car in your town suddenly becoming all electric and a third of them need a charge or the driver will be late for work. This will take a lot of time and money.
  • Kendahl One thing I've learned is that cars I buy for local errands tend to be taken on 1,000 mile trips, too. We have a 5-speed Focus SE that has gone on longer trips than I ever expected. It has served us well although, if I had it to do over again, I would have bought an ST. At the time of purchase, we didn't plan to move from 1,000 feet elevation to 6,500. The SE is still adequate but the ST's turbo and extra power would have been welcome.
