Audi has scored a hat-trick of category wins at the What Car? Used Car of the Year Awards 2019. The German car maker won Used Family Car of the Year (Audi A3), Used Luxury SUV of the Year ((Audi Q7) and Used Coupé of the Year (Audi TT). However, the 2017 Mercedes E-Class Estate claimed …
These lightweight multi-carb, four-cam and even Hemi engines were being developed for future production engine research and, in some cases racing projects.
Between 1969 and 1970, Oldsmobile Engineering was responsible for creating powerful ultra-efficient 350 to 455 cubic-inch V-8 engines rated up to 700 horsepower! Some were naturally aspirated and fitted with single Quadrajet four-barrel or Weber carburetors; others were fuel-injected and turbocharged. Most had aluminum blocks and heads. It was hard to imagine that these engines were anything other than veiled attempts at building pure racing engines, but they actually were. Oldsmobile engineering used these engines as prototypes for developing lighter, more fuel-efficient and “cleaner” production engines.
Olds engineers were responsible for the radical OW-43, above, a racing-only, four-cam 455 tested with four Weber carburetors and fuel injection with three-inch ram stacks. The OW-43 was developed at the same time Chevrolet Engineering was working on the ZL1 for Corvette and Camaro applications and Can-Am racing. The OW-43 was tested in a Can-Am racecar, but never used in competition.
Based on the same bore-stroke configuration of a production 455, the OW-43 had heads and block with steel cylinder liners cast from Reynolds 356-T-6 heat-treated aluminum. With a redline of just under 8,500 rpm, it produced 600 horsepower at 6,000 rpm with Webers and 700 horsepower at 6,800 rpm with Lucas direct-port fuel-injection. The DOHC prototype had Forged-True 12.20-to-1 pistons, Carillo billet steel rods and a forged steel crank. It weighed 50 pounds less than a production cast-iron 455.
The mildest of the group was an all-aluminum 350 small-block, displacing 389 cubic inches and utilizing dual-throat Weber 48IDA carburetors, above, right. The alloy 389-inch engine ended up in a Cutlass that was driven to the C/Production record at the Bonneville Salt Flats in 1968. A friend and editor at Hot Rod, Lee Kelley, drove a factory-supplied Cutlass 169.133 mph to set the record. Apparently during impound, SCTA officials never detected that the engine was an all-aluminum prototype.The engine in Lee Kelley’s record-setter was a one-off, rated at close to 500 horsepower and built in Lansing by Dave Maurer, a special projects engineer. At Bonneville, the Cutlass was crewed by Maurer along with racing legends, Ak Miller, Jack Lufkin and Ed Iskenderian.
One of the most interesting engines was the 455-inch W-43 Hemi. There were cast-iron and aluminum iterations with four-valve, Hemi-chamber heads. The W-43 engine was designed to be easily converted to chain or gear-driven overhead camshafts. Fitted with a single Quadrajet, it produced in excess of 500 horsepower at 6,500 rpm. The aluminum version weighed 75 pounds less than the then current production 455 engine. This engine found its way into Mule cars tested at the Milford Proving Ground.
Oldsmobile engines displacing 389 to 455 cubic inches had powered Can-Am Series cars, like Bob McKee-built Cro-Sal racers in 1967. The highest output Can-Am Olds was an all-aluminum, single-cam 455 with injection and twin turbochargers. It generated 659 horsepower at 6,250 rpm and 554 pound-feet of torque at 6,200 rpm.

There was no question that the 2016 Ford Focus RS was going to be quick. That was always a given. No, the question was always “how quick?”.
Now we know. With 350PS and 440Nm the turbocharged 2.3-litre Ecoboost propels the Focus to 62mph in just 4.7 seconds and on to a top speed of 165mph. That’s nearly a whole second faster than the previous fastest Focus, the RS500, and it’s a lot cheaper than that limited edition RS.
It’s hardly a surprise that this is the fastest accelerating RS model ever, that’s progress for you! What is a surprise is the price that Ford are asking for this level of performance – just £28,940.
In terms of thrills gained against hard-earned money spent there’s nothing that can touch it. It’s cheaper than a 300PS Golf R and makes the Leon Cupra, Megane Renaultsport and Astra VXR look under-endowed. What it emphatically does is stick two fingers up at the Audi RS3 and AMG A45, who tried to convince us that almost £40k was acceptable for a hot hatch. Jürgen Gagstatter, chief program engineer for Focus RS, puts it quite politely:
“The all-new Focus RS delivers stunning performance and innovative technology at a price that will make both our customers and premium automakers look twice. After experiencing the acceleration and cornering capability of the Focus RS, drivers will question the sense in spending almost £10,000 more on a premium competitor.”
So in other words, you’d have to be barking mad to spend another £10k on one of the German rivals. Unless you really, really want some of those pretty headlights.

Remember the SEAT Leon Cupra 280? Launched at the start of 2014 to a flood of praise and accolades (including from myself), it was seen as one of the best hot hatches on the market. Well, that’s so last year, because the Cupra 280 is gone.
Instead we’ve got a Leon Cupra 290 and, as you might have guessed, it’s got a power increase of 10PS courtesy of a mild ECU remap. Which might not seem like much but, as a certain supermarket giant likes to remind us, every little counts. It takes the Leon’s output even closer to the Golf R, beats the Focus ST with ease and matches the Megane 275’s recent power hike.
Not that you’ll notice much difference. The official acceleration times for the Cupra 290 are exactly the same at 5.7 seconds for the DSG and 5.8 for the manual transmission and top speed is still limited to 155mph. Economy and CO2 emissions are identical but the peak torque of 350Nm is at least available across more of the rev range than before, from 1,700rpm all the way to 5,800 rpm.
Of course, you could go to an aftermarket tuner and get 4 or even 5 times the power increase along with some extra torques for a few hundred quid. The trouble is that might upset SEAT’s warranty department so if you want a little more power this is one way of getting it without affecting your Leon’s warranty.
No official word on prices yet but expect to see a slight increase from the 280’s £28,485 OTR.
