      Chevrolet Spark turbo (1.4t from the Sonic/Cruze)

      This'll get the engine-swapping juices flowing...



      GM Europe has goosed its A-class Spark city car with the engine from the Sonic / Cruze to act as the pace car for the WTCC series (World Touring Car Championships).

      This spiced version of the Chevrolet's city car, equipped with a 1.4 turbo and 140 hp engine, has been entrusted the key task of leading the pack in the WTCC, as it will be the official leading car in selected events of the series. The Spark WTCC Leading Car will be displayed in public for the first time at the WTCC round in Zolder on 19-20 June.

      • In case you forget: the 1.4t is rated for 138 jp / 148 ft-lbs of torque in the Cruze & Sonic. Euro HP numbers show 140 though.
      • Curb weight of the Spark is ~1900 lbs


      GM has been saying for a while that it's considering bringing the Spark to North America in 2012. Maybe, maybe not. That'll depend mostly on where gas prices go from here, I suspect.

      If the proposed "Z" tuner arm of Chevrolet takes off ( a poll and prompting from like-minded members here and on related boards- and then a message sent off to GM? ) would be a way to fit this combination here in the states... wonder how different the electrics/computer engine /trans package is from model to model? As an example the 1.4T/6 speed manual in a Sonic – and then the same power train in a Cruze. I understand the gearing is different between the two.
      Nonetheless the package from a Sonic would be fairly appropriate on the Spark ( the gearing in the first three gears might be a bit short since it would be designed for a 500+lb heavier car- (minor alteration could come about by picking a taller wheel/tire combination ). The question would be would it pass emissions/legality in the 50 States? if not the latter- perhaps the former? What are the bore/stroke/head relations between the 1.4 and the optional 1.2 in the Spark?

      Steve

      thus far have found 1.4T specs: 72.5 mm bore/ 82.6 mm stroke
      and 1.2: 69.7 mm bore/ 79 mm stroke
      just for fun- the 1.8: 80.5 mm bore/ 88.2 mm stroke

      the instructive aspect would be head details, block/transaxle bolt pattern, and block bore spacing/deck height

      daewoo is a lot like the european format, where the drivetrains are almost interchangeable.
      Since all three of those cars (spark, cruze and sonic) are daewoo. it should be more feasible than we all think. I know the 1.8 ecotec is a "direct" swap for the ecotec aveo. So that might mean if the body harness is the same, the 1.4t is a direct swap for the aveo. As long as the us manufacturer didn't change the pin out or style plugs etc.

      From a marketing perspective- so as not to undercut Sonic sales, a "Z"ti Spark w/ 1.4T and 5 speed manual with a slight detune and upper range wheel/ tires in the 14-185/60- or 15- 195/55 ( depending on what the current base/optional wheel/tire range is for the model ( 13" as the base?) would still deliver a desireable pocket rocket that would also be in its own class, one that doesn't inherently cannibalize sales from a hotter Sonic ( though it might draw a standard Sonic package buyer- however- having less features- afive speed instead of 6 and a lower output might mean that only those looking for sportiness with maximum economy and more affordability would buy it instead of a base Sonic- I see room for both- catering to different audiences ).
      Opinions? Facts?

      Ok Rabbit, so the feasibility from the technical perspective looks favorable. What about the marketing considerations as I outlined directly above?

      Interesting topic. in a few years after we pay off my wifes corolla, we are buying a truck (98 to 04 crew cab tacoma v6 4x4). If my Aveo is still an ongoing project at that point (not dead yet LOL), this may be something to consider

      i dont see gm overcoming themselves.. but look at the audi and bmw line up..
      standard a4 ($34) premium a4 (@$40) then the s4 ($50k) then the rs4, which was priced the same as the flagship a8 ($80k).
      All the same body.. the a6, s6 and rs6 did the same overlaps and the a8 and s8 as well.

      the engine were basically stuffing the "common" largest engine of the next size up car t make the s series. the premium would be the base engine of the next size up.. the rs was always a special tune or turbo version (or v8 turbo) of the s..

      i think gm could make it work. but they hve to get out of the huge ass suv is good, cheap cars are bad mentality.

      i think gm already failed in that the 240hp cobalt ss was cheaper than the 140 hp cruze. And anything gm does to hop up the aveo its gong to be competing against gti, wrx etc now for the newer price point which it doesn't stand a chance. If it still was against the yaris, hyundai etc. it would be the winner.

      Ok the very last point has me confused. Can you clarify competing against the gti, wrx, and the like? Their price point is much higher isn't it? Even if they are lower priced than before- I don't see parity between them and the Sonic/Aveo by any stretch. The R will likely be in the mid 30's. I haven't seen how the other variants stack up but I don't see direct competition between VW in the Golf line-up and the Sonic/Aveo. Perhaps the new Passat and Polo but then GM has the Cruze against the Passat. The lower end of the Cruze range could handle that as well as the upper end Sonic sedan.

      Therefore, only a hot Sonic or Spark ( which would then be paired off against the likes of a Polo gti, and a hot Fiesta, Fiat 500, etc. ) would approach those models. The gti I don't see as much of a benchmark unless you consider the largest engine in that- but then you're talking 30k.

      Regarding GM's past views and marketing approach- I see that rapidly changing with both the new management team at the top and the spate of new models on the small end of the scale. we have to give them a chance to either sink or swim. Viewing their efforts with skepticism sinks the ship before it leaves port in my view. Not saying your perspective is pessimistic per se, yet I don't see a Sonic customer being a direct cross-reference with a Rabbit or Golf one ( they need to decide which name to stick with– and the mental hopscotch with model names and US spec- look at the shenanigans with US spec Polos- going on at VW suggests all is not well uber alles with the Wolfsburg fleet ).

      I'll say this- if looks and price are considerations– the new Sonic has it all over even a G or R gti and definitely trumps the frumpy looking Polo gti and even the edgy ( even ugly- but in a cute, strangely attractive iconic fashion like the original Beetle- or AMC's Gremlin- yes- the Spark is– pardon the pun– igniting my interest– )Spark has that potential.
      If you are talking about how much car you get in a wrx or gti- yes- you get mucho mas- but you pay for it too- hence my argument here.

      thats your opinion.It makes sense, but i dont agree with your classification.

      A passat is more of a malibu, or impala. Just be size, engine, price. If you think they compare, or someone made that comparison, that is marketing.

      I think the aveo is a great $10k car. but when you think the cruze 1.4t 6 speed is @ $20k, i don't think it competes as well in the market. Once you hit the 20k mark, the GTI, WRX, etc are withingreach. and more appealing. Especially with only 140hp. The cobalt SS was the same price with 260hp and LSD. The spark would have my bet as long as it stays under $13-14k with 140hp.

      I personally like the polo gti, its styling is very different from chevy, but its also 178 hp out of 1.4l..

      Here's the deal:
      my classifications follow this basis:
      1) Chevy is GM's VW
      2) Buick is GM's Audi
      3) Cadillac is GM's BMW

      With the above generalizations- this is how models stack up:

      Passat- as per VW's edict this is a volume model- therefore future, not present- but future Passats will be "US" ( Mexican built- so North America ) and pricing will begin at $15,000 or so and will be larger than the current car- perhaps because of the pricing and the upcoming size- and I hadn't thought of it this way- it would be the Malibu ( but not Impala- even today the Impala is at the top of the Chevy size heap- as it always was historically- with the exception of the sixties and seventies – when the Caprice supplanted the Impala in the largest size slot ) of the VW line-up.
      However, I feel that the Cruze represents the future in a front-wheel or front- wheel based awd platform ( if Chevy expands their rwd model proliferation I see the Malibu or impala or even a resurrected Chevelle nameplate with a Malibu "plain Jane" offshoot ) and that the Cruze competes with the Passat with Buick covering Audi up to a flagship model- with Cadillac picking up the positioning chalice at that point as well as Cadillac going toe to toe with BMW. If GM picks up their rwd platforms than logically the present GS Buick could assume it's true historical role as arwd "gentleman's express" and could line-up against the middle spectrum of sporty Beemer offerings as well as emerging as a true modern muscle car ( a highly sophisticated one- mind you- competing domestically with the Dodge Charger )

      Back to the hot hatch segment. The Sonic ne` Aveo no longer is a $10,000 platform, hence the nameplate change for the US- the re-positioning of its market position. The size increase, extra standard features, upgraded materials, Cruze platform powerplants and edgy styling all point to that. True- the same car unveiled months early in Korea and badged as the Aveo- and I don't have its a particulars down other than it is powered by a 1.6l engine– is carrying the older car's torch in name- but then- the market in Korea is considerably different than the one in the US.

      Looking long and hard at the new Sonic look at the radical shift in choice and technology represented by some of the following details- as compared to the out-going Aveo: 2 engine choices- one of which is a turbo - 2 six speeds- one auto- the other manual- and a manual 5 speed ( which could be the trans for a possible turbo Spark ) electronic power steering- gps- traction control- anti-lock braking, standard a/c- timing chains and other more sophisticated engine design features. The list goes on. The attention to NVH and maintenance issues means that Chevy has alot of hope and serious effort engineered into the car. The natural competitors encompass Yaris, Fit, Versa ( really no competition there ) and Fiesta. I also include the Polo.. The Polo- particularly the gti is good looking. However it's not breaking any new ground stylistically and I happen to be more partial to the Sonic- even in regular model guise. Personal preference. Agreed that the the Golf as competition is a bit of a stretch.

      For the Cruze to truly compete against the Passat Chevy will have to offer a more entry level version- perhaps based on the Eco version. A hatchback version could bridge the Golf gap. We'll see what the future brings. Right now GM has kept on a track that roughly equates to Ford's by offering a new model or two per year and really focusing on what will have to emerge as the bread and butter line- sedans and hatchbacks with efficient powertrains.

      Yup, my opinion, backed by facts and a logical perspective of where GM and the Aveo started and has come from to where the focus and placement are now.

      Steve
