Caterham gets Suzuki power

New sub-£17K entry-level Seven gets 660cc Suzuki turbo engine



Caterham has confirmed that its new entry-level Seven will be powered by a three-cylinder 660cc Suzuki engine, not the Ford Ecoboost we tried out last year. Set to cost less than £17,000, Caterham claims the new model will be the 'lightest Seven ever', not to mention the most efficient too.

Take the live axle from this (possibly)...
Take the live axle from this (possibly)...
The turbocharged Suzuki motor has been breathed upon by Caterham Technology & Innovation and while it all sounds quite high tech the firm is making much of the back to basics approach of the new car. And when Caterham says basic you can bet that's exactly what it means.

"We needed a particularly light powertrain but it had to be a unit that suited the characteristics inherent to all Sevens," says Caterham boss Graham Macdonald in the press release announcing the car. "Suzuki is a leader in producing compact vehicles with extremely efficient engines and that is clearly a shared passion. Thankfully, after lots of hard work, we have a package that works brilliantly."

Numbers are sparse in the Caterham press release but Macdonald does say: "Unfussy and easy to run, it is designed to give a neutral, supple ride yet carrying the sporting edge and turn-of-speed expected from any Seven."

...and add the turbo 660cc three-cyl from this...
...and add the turbo 660cc three-cyl from this...
We wanted more information though, so we pestered Caterham. And we got some additional technical information, revealing that the new car has 'carry over' Seven S3 narrow track front suspension and a relocated steering rack to - depending who you ask - 'refine steering feel' or make room for the intercooler.

It also reveals that the new car will use a Suzuki-sourced live axle fitted with CTI designed trailing arms and Panhard rod, which explains one way in which costs have been kept down.

So how much power will it actually have? Well, it'd seem Caterham has had a right old rummage around the Suzuki parts bin and a protracted virtual equivalent on the firm's Japanese website here in the PH office leads us to believe the engine is the turbocharged version of the K6A three-cylinder fitted to a range of JDM Kei cars. In standard form it makes 52hp and 56lb ft, the turbocharged version used in the Lapin and Wagon R Stingray (yeah!) upping that to a heady 64hp and 70lb ft. And that beam axle? Well, the pint-sized Carry pick-up has a dinky leaf-sprung, live-axle set-up, five-speed manual and uses a version of the K6A engine...

...to create an affordable, back to basics Seven
...to create an affordable, back to basics Seven
Now, if Caterham can get the new car to sub-500kg (an R500 is officially 505kg, a basic Roadsport 1.6 550kg) to live up to that 'lightest Seven ever' design goal that equates to 128hp per tonne with that 64hp at a nominal 500kg, compared with 228hp per tonne for a 125hp 1.6 Roadsport. But you'd have to hope CTI can tickle a bit more power out of it and in the additional info supplied the car is referred to as the 'C180'. That'd mean 90hp at 500kg as a ballpark but even 80hp and 150-160hp per tonne would have it on a par with a GT86 or MX-5 and, in a stripped back Seven, enough to have some fun.

More concrete information when we have it but if you're keen orders open in the autumn with first deliveries before the year is out. The official release can be seen here.

I'm not a power mad type person and well into the whole add lightness but that sounds a little low... hopefully the super charger adds a bit more oomph to that?

Not saying you need it necessarily but would be nice...

A slightly later version of the engine fitted to the Suzuki Cappuccino - great fun little engine and plenty of tuning scope. Will be interesting to find out exactly how and where Caterham have breathed on it.

Having run a 125 Sigma powered 7 for the last 6 years with 228 bhp/ton I can't see much attraction in the power-to-weight ratio quoted in the article for a car with the Suzuki engine.

Still, if Caterham think there's a market for it good luck to them.

12hp from boosting the engine, is it even worth it??

Looks like a good entry point to Caterham ownership. I suspect Caterham hope owners will later upgrade to one of the R-cars.

I love the idea of a £17,000 sub 500kg Caterham.
I don't particularly like the idea of a sub 100bhp forced induction Caterham though. It would feel like an awfully long wait between the corners...

Nice replacement for the "Classic" using a more modern engine.

If they can get the power approaching the 100bhp mark, then it'll be a bit of a laugh this one - especially on the skinny tires pictured!

It has the be on or around 100 BHP in my view.

That would make it a worthwihle option to those looking at the second hand market for standard Xflow / Vauxhall OHC engined cars, which have around that kind of power and can be picked up for £10k ish.

If there is tuning potential to take it over 100 BHP, then even better.

If the weight is low enough will they be able to class it as a quadricycle rather than a car? Could make it even cheaper to run then.

The I3 DOCH 660cc 12V in the cappuccino can push 100hp... with fettling....

I'm not sure why you would pay £17k and put up with the "no-frills" nature of a 7 in order to access such mundane performance. It seems like a step too far along the "back to basics" route when even a luke warm hatch could go just as quick with a roof and a boot!

The only buyers I can think of are older folk who would potter around in it, in the same way that you'd use a classic car, but would many of them manage to get in and out of it OK?

I take it you haven't driven a 7 then

That's a 23% increase, but hopefully it'll be closer to 100BHP.

Caterham's aren't all about headline grabbing performance (although admittedly the top end ones probably are), they're about the driving experience. There's nothing like driving a Caterham, even when you're not setting lap records.

Is that £17k built or kit form?

It's a Japanese market tax/insurance/parking thing.

Kei class cars (which this engine comes from) are limited to 64ps (actually 63bhp) by law, in order to fit in the "Kei" class (which has strict dimensions and power limits). A car built to this regulation is treated a bit like we treat quadricycles over here, rather than proper cars. It also permits use in some places where the user can't prove they have space to park it (which in Japan is a problem)

What do you suppose it'd be capable of without that legally proscribed limit? 80bhp? 100?

...my advice, take the passenger seat out as if you ever carry one you feel a big difference in performance...almost identical power to weight ratio as an mk1 mx-5, definetly one for the corners...

I really dont understand who would buy it for that money. There are so many kit versions of the 7 about that would be far less money with far more power.

The big ones are lovely and I can understand why they get bought but this? Also if they wanted a small engine from suzuki why not one of the bike engines which make over 100bhp out of the crate!

Will this bring down the average g/km for the fleet???

Clever move.......

I hope some of that weight saving comes from giving it skinny tyres so that you can still break traction.
