VW admitted this themselves
When they faked their emissions readings to try to get engines approved
Strict standards and engine longevity are not mutually compatible


They can be, a modern 6 with it's design and lubricants will do a lot more miles than the 80-100k miles you would get out of a Holden red 179 EH. VW had to cheat because their engine wasn't up to scratch for modern standards. Running an engine lean for eg when it's on test or at any time will cause heat, wear and oil breakdown. BTW, I do not know what VW did to fudge the tests but I'd suspect the ECU could detect testing to a degree or they could be switched to it.

High tech doesn't always mean better

The electric power steering on my 2016 Kia Cerato is the worst steering I've ever experienced. I've owned a lot of different brand cars over the years, but this Kia has only done 35,000ks and still under warranty, previous elderly lady owner

The steering is stiff and notchy at speeds above 40kh, the Kia dealer said it's normal. I fitted brand new tires and over-inflated them from 32 to 38, got the wheel alignment checked and adjusted, but still there's a "stiff" feel to the steering. This is not high-tech, it's just bullshit

My old Corolla was heaps better and it had no power steering at all. That Corolla also had an Aisian auto, said to be 3sp, but it had a 4th gear overdrive that you never knew it had unless you carefully listened to the revs or felt the very slight hesitation of the car when going up a grade. Never felt it go into that gear though, there was no switch for it. I miss that gearbox, it was pretty good

The Kia has high-tech stuff for the engine, brakes, millage read-out and other sensors, but the rest of the car is very ordinary. The door catches and handles act like, and are no better than old Kelvinator fridge doors, before magnetic door seals. The hatch door opens and closes a bit like a tilting garage door and if it's not closed fully, the battery goes flat, you may not know. The bonnet must be slammed down to shut it, gently pushing it down will dent the sheet metal because the bonnet is that hard to close. You can feel every change from the auto box most of the time, and the curved side rear-view mirrors give a false impression of how far traffic is away from you ... and then there is the terrible power steering, not worth a pinch

One saving grace is the low fuel consumption, but only if driven at moderate speeds, fast speeds on or over speed limits just ruins fuel economy, it's then equal to my 3.0L diesel van

However, on one long stretch on the way home from town, I get 4.3 Lts/100ks from the Kia, but that's in 5th gear, not 6th, and doing 70-80 kh. 5th gear takes load off the motor and the accelerator pedal is not pressed down as far, so not as much fuel is needed. The 4.3 was displaying on the dash millage computer read-out. The engine is a 1.8lt, so, not bad in that regard





great review, thanks

various scams like "stop start " technology to turn the engine off at a red light or
shutting down 1/2 the cylinders in a 8 or 6 are designed to try to get good figures to pass european emssions and fuel consumption tests.

they are probably bad for the engine.

and a few dollars saved in fuel is nothing compared to reduced longevity

A long time ago I borrowed a Corolla.
Magnificent car. VERY solid, had the feeling it would run forever.

about 3 years ago I had a hyundai as a rental, so it was a new car.
Awful thing. Same as you said.
Tinny, cheap, was NOT made to last a decade.

There's more nickel in modern engine metals. The Japanese were hungry for nickel in the 60's and 70's and Qld Nickel turned poor investors into millionaires. Nickel is slipperier than cast iron so, more nickel in the cast iron and steel, longer wearing
