BMW Vision iNext to be first car on bold new platform

Production version of the semi-autonomous concept will be the first on BMW's versatile new architecture

The production version of the BMW Vision iNext concept due in 2020 will be the first car from the firm to use a radical new platform that will enable it to produce conventional internal combustion engine (ICE) vehicles, plug-in hybrids and pure EVs using the same basic architecture and on the same production line.

The Vision iNext concept is on display at the Los Angeles motor show, along with several of the systems BMW is developing for its advanced autonomous systems.

The production version of the iNext concept – which BMW is terming a ‘Sports Activity Vehicle’ (SAV), in a nod to the original X5 from 1999 – will be built on the new architecture that will underpin future BMW models from the 3-series upwards, and will allow a rear-engine configuration in some. 

The firm will build all of its future models on two platforms, one for front-wheel drive cars and one for all- and rear-wheel drive machines.

On the latter platform pure EVs, such as the Vision iNext, will use a rear-mounted drivetrain as standard. Plug-in hybrid models will have both a rear-mounted electric engine and a transversely-mounted ICE driving the front wheels. Pure ICE models will retain the classic BMW rear-drive layout.

Other options will include twin-engined all-wheel drive EVs and conventional mechanical all-wheel drive ICE models. 

BMW sources say that the maximum range of the pure EV models could be up to 450 miles in future X series cars (which are likely to have a bigger battery capacity), while the plug-in hybrids will get a range of around 60 miles.

The new architecture will also incorporate a new autonomous technology platform which will eventually offer level five autonomy, which does not require a driver. BMW showed all three prototype autonomy ‘PAD’ processing units in LA, the smallest of which will first appear in 2021 on the production iNext offering ‘hands off and eyes off’ level three autonomy at up to 80mph on motorways.

The level four and five autonomous systems will enter testing in 2021 on a fleet of pilot cars. Level four aims for ‘hands off and mind off’ autonomy in urban situations, while level five will offer driverless urban travel at up to 70kmh.

The somewhat controversial styling of the iNext reflects the new vehicle in only a ‘broad-brush’ way, according to BMW insiders. However, the real thing will be a crossover.

Expect the sheer surfaces, especially around the sides and rear, to be translated into production, along with the large windows and an interior that sees much of the switchgear blended in the interior as touch-sensitive surfaces that appear on demand.

BTCC 2018: Neal wins Diamond Double at Snetterton

Neal clinched victory in the extended Diamond Double race Jack Goff stars in qualifying and race one, while veteran Neal clinches glory in double-length finale Triple British Touring Car champion Matt Neal clinched victory in the special extended Diamond Double race at Snetterton, held to mark the 60th anniversary of the series in his Honda Civic Type R . Rising stars Jack Goff and Ashley Sutton also took race wins at the Norfolk track. Instead of the usual reverse-grid finale, the third race at Snetterton was extended from 12 laps to 20, with double championship points on offer and no success ballast. The race also featured its own separate qualifying session. Picture special: 60 years of the BTCC That was good news for Eurotech driver Goff, who went fastest in both qualifying sessions to claim two pole positions in his Civic Type R. He made the first one count, pulling out a big lead in treacherous wet conditions.  The young guns of the BTCC Behind Goff, reigning champion

Japan's micro sports cars – Honda and Daihatsu kei cars driven

S660 and Copen are the only kei sports cars in production Kei cars are big in Japan, but do they deliver driving thrills? We sample a pair in Tokyo to find out When the American style of christening storms came to Britain a couple of years ago, it was inevitable that some wag in the Met Office would find a way to undermine the whole concept with an underwhelming name to snigger about.  Storm Brian was the result. It’s a fine English name but perhaps lacking the gravitas of many of those coined overseas. “In terms of impact, we’ve had spray overtopping quaysides,” someone from the Environment Agency told the BBC of Brian’s pummelling of Cornwall. Top marks for not trying, Brian.  While Brian was doing his thing on the other side of the world, Typhoon Lan – now there’s a name – was homing in on southern Japan, bringing with it 140mph winds and a storm that made photographer Stan Papior wish he’d invested in a waterproof camera and jacket.  Look really closely at some of his pictur
