The unthinkables: 10 of the most controversial car innovations

Honda has long been a hard-line exponent of naturally aspirated engines, such as the VTEC units in a long line of Civic Type R hot hatches that stuck with natural aspiration long after competitors went turbocharged. Yet it wasn’t long before the Honda looked weak-kneed next to rivals, so the unthinkable happened in 2014 and the Civic’s VTEC gained forced induction. Performance gains were huge, but some of the magic was lost. Honda learns fast, though, and the latest blown Type R is the best yet.

Porsche Cayenne

Nearly a quarter of a century on, it’s easy to forget just how controversial the first Cayenne really was. Porsche was a dyed-in-the-wool sports car manufacturer and to even be thinking about the possibility of just maybe making an SUV was heresy, especially one that would go on to have a diesel engine. There was no precedent for this car and, allegedly, no appetite for it among zealots of Zuffenhausen’s usual offerings. Yet as we now know, the Cayenne was a massive sales hit, helping Porsche to ride the early SUV wave and on to previously unimagined profitability.

Volkswagen K70

It can be hard to break free from design dogma and, for decades, VW stuck to its tried and tested formula of slinging an air-cooled engine behind the rear axle. By the late 1960s, however, VW was being left behind commercially and technically, so a revolution was needed. Step forward the K70. Based on the NSU Ro80, it ripped up the VW playbook by featuring front-wheel drive and a water-cooled inline engine. Rust issues and high prices meant it was short lived, but the Volkswagen Passat, Volkswagen Golf and Volkswagen Polo that followed used the same layout to dazzlingly successful effect.

2WD Land Rovers

When your products are tightly entwined in four-wheel-drive folklore and your best remembered advertising tagline is the ‘Best 4x4 by far’, then going two-wheel drive should be a no-no. Yet that’s what Land Rover did with its Freelander 2 eD4 in 2011. Aimed at lowering emissions and running costs, it dispensed with the standard car’s propshaft and rear differential, yet it retained Terrain Response and mud and snow tyres, making it as effective off road as some of its all-wheel-drive rivals. It was so successful that it spawned similar Range Rover Evoque and Discovery Sport models.

Ford

Most of the examples here are of individual cars but, in the past year alone, Ford has played fast and loose with its heritage. First up was the Puma, which applied the name of a much loved 1990s coupé to a crossover. There was resistance from some quarters but, in many respects, the new car retains the fun-loving spirit of its predecessor. Likely more difficult to swallow will be the Mustang Mach-E, which is aiming to channel the essence of the firm’s famed muscle car into an all-electric SUV. Ford will be hoping it doesn’t make the same mistake as when it applied the RS1800 moniker from its rally-winning and bespoke-built Escort Mk2 to a tarted-up Ford Fiesta.

Front-wheel-drive BMWs

BMW believed you couldn’t claim to produce the ‘Ultimate driving machine’ unless you made your cars rear-wheel drive. For decades, even its smallest models sent power to the rear. Then in 2014, it launched the front-wheel-drive 2 Series Active Tourer, based on the same platform as the Mini. BMW fans were only mildly upset because, well, it was ‘just’ an MPV. Then came the bombshell in 2019 when the 1 Series turned from rear- to front-wheel drive. But despite howls of derision from some quarters, the switch hasn’t harmed the car’s engaging driving dynamics.

Porsche 718

Porsche has the best part of 80 years of experience with four-cylinder engines but that didn’t stop purists getting extremely hot under the collar when the 718 Boxster and Cayman were launched in 2015. By ditching the howling flat sixes of previous generations for turbocharged flat fours, Porsche took a hit, both critically and commercially. Initially, the brand stuck to its guns but soon plans were in place to secure the return of the naturally aspirated six. The result was the Cayman GT4 and Boxster Spyder, which were swiftly followed this year by the GTS 4.0.

Skoda Favorit

Like VW, Skoda seemed happily wedded to a rear-engined formula for decades. But with the Iron Curtain crumbling in the 1980s, the firm knew it needed a radical rethink if it was to tap into lucrative Western markets, and so the Favorit was born. Its five-door hatchback layout and front-wheel drive were revolutionary for the Czech brand but, thanks to some help from Porsche (yes, really), Bertone and British firm Ricardo, it proved to be a surprise hit. In fact, it was such a success that its fellow adherent to the rear-engined rules, VW, bought the company.
