Naturally Aspirated Cars

Wait... I thought you said you didn’t want a hot hatch? They’re fine and all, but a completely different proposition to a RWD coupe.

It's not really fair enough at all, generally a turbocharged engine will be more fuel efficient than a similarly powerful normally aspirated engine because it needs less capacity to make that power.

This is why there are so many small turbo engines now.

Agreed, but he seemed pretty set in his ways, so couldn’t be arsed making a case.

Smaller and lighter yes but they also have to run the mixture richer to prevent knocking so the gain is not as big as you would think, especially with a heavier foot.

Problem is the tests don't really reflect real world driving for most people. If they did, we wouldn't see small turbo engines doing nearly as well on paper.

We have engines built for "beating" the test (lol VW), rather than actually being the best they can be.

Mazda's EGR tech makes zero difference to the tests (low load) but improves their real numbers, it discourages them from spending money on it as it does not improve their spec sheet and makes the car a bit more expensive.

For me perfect toy atm wpule be BMW E36 just love sound of that i6 engine.

yes - can't beat the sound of the vanos on full song 4.5k-6.5K and linear i6 power delivery.

To be honest I had my mind set on a GT86/BRZ from the start and think that’s what I’ll be getting.

So turbos can get lost cos I WANT NA.

Just need to decide on either an auto or manual.

Manual, surely? Might as well get a turbocharged car if all you're going to do is bang a torque converter auto behind it (unless, of course, you need an automatic for a specific reason).

Lowe · 7 Mar 2019 at 14:32

Manual. For the love of God manual. Auto 86's are slooooow!

Well my commute is 15 miles of 75% traffic and 25% foot down and go.

My other car (2018 Honda CrV) has an autobox which had terrible pull away speed being an auto as it isn’t instant, so not sure on an auto.

It has terrible pullaway speed because it's slow, not because its an auto. There is absolutely no way I could pull away at the same speed as my auto manages of it was a manual!

Agree with Fox. Hence 0-62 times for cars which have an auto and manual options are almost always faster for autos.

Cliffhanger · 7 Mar 2019 at 15:11

Well I am gonna test both and let you know the outcome.

BRZ or GT86?????

bJN · 7 Mar 2019 at 15:32

Thought you needed to use the rear seats, what happened there?

Correct me if I’m wrong... but I thought they’re basically the same car just different badge.

Lowe · 7 Mar 2019 at 15:49

Basically the same yes but there are differences.

Different front bumpers and lighting design up front.
Slightly different interior as well with some of the panels being a different colour.
On the pre-facelift the spring rates are slightly different (the 86 is a little more tail happy as a result)
Interior dash instruments on BRZ are the poverty spec ones, black dials.
BRZ stereo is especially poor.

The real kicker though is the dealers. Subaru dealers are basically a nightmare when it comes to warranty. Toyota dealers are much more lenient and some are downright fantastic (RRG Macclesfield I'm looking squarely at you). I went Toyota and am very much glad that I did!

Cliffhanger · 7 Mar 2019 at 16:04

I have owned 3 Toyotas and all of them have been bullet proof hence why I am looking at the GT86. The dealers have also been great aswell, much better than Nissan and Honda....

Only if it's a dual clutch box, but the auto in the gt86 is a torque converter. The manual will do 0-60 in around 6 sec with sticky tyres and some practice. But that isn't really what the car is for.

The ZF8 on my BMW isn't dual clutch as far as I know and it's faster than the manual. Same with other BMWs with either option. There's no practice needed, just put your foot down.

That said in a car like the GT86 the manual is the only option to consider IMO.

The auto's gears are also quite a bit longer so that probably doesn't help either. It's definitely not as quick as the manual, it's well tried and tested.

Cheaper road tax though, so that's something.
