Tesla's chief has pledged to make a pick-up truck as part of future plans for the electric vehicle-maker.

Elon Musk made the promise on Twitter after asking his followers for suggestions about how the firm could improve.

He said the open-backed truck would follow the Model Y - a yet-to-be detailed car, which is expected to be based on its Model 3 sedan.

But experts note Tesla has suffered repeated delivery delays.

That has led some to question whether the loss-making company can meet its existing commitments - which also include a forthcoming articulated lorry and sports car

Mr Musk also made several promises about new features Tesla intends to add to its existing vehicles, including intelligent windscreen wipers.

Pick-up trucks are particularly popular in the US, with sales by the three leading manufacturers currently totalling about $90bn (£67bn) a year, according to data from Morningstar Equity Research

Demand for the trucks has also risen over the past 12 months, despite a drop for other types of "light vehicle".

Mr Musk had previously hinted at his plans when an image showing an obscured pick-up was briefly shown being carried on the back of its Semi lorry at a press conference in November.

In his tweets, Mr Musk said the vehicle would likely be "slightly bigger" than Ford's bestselling F-150 pick-up to allow it to contain an unspecified "game-changing" feature.

"[I] have had the core design/engineering elements in my mind for almost five years," he added.

In addition, the entrepreneur also appeared to make several commitments to requested updates for its current vehicle range via a series of brief replies, including:

windscreen wipers that automatically change speed based on how much rain there is - a facility already offered by Volkswagen, Volvo and Mazda, among others

"vastly better" maps and sat-nav software

a revamped web browser for its cars' touchscreens - experts have described the existing version as being "almost unusable"

a "disco mode" for its vehicles' interior lights, timing them to the beat of music

Mr Musk's ambitions contrast with Tesla's recent performance.

In November, the firm declared its biggest quarterly loss to date - $619m - and admitted that it was months behind schedule with Model 3 deliveries.

It said that problems with battery assembly and steel welding were among reasons for production bottlenecks.

News agency Bloomberg subsequently warned that if the firm did not slow down its losses it would exhaust its cash reserves in 2018 unless it raised fresh funds.

"There are a growing number of people who are looking to Tesla to fulfil on its existing promises rather than make more ones," Paul Newton, an analyst at the IHS Automotive consultancy, told the BBC.

"It has a large number of back orders for the Model 3, and only a handful of painstakingly hand-built cars have been delivered.
